We started the week discussing stability and how we define it. We then went through the big three with week - Alkalinity, Calcium and Magnesium. We've discussed others in the past. Let's end this week with what people feel is the most important parameter to maintain stability in a mature reef.
Now, I realize stability is of vital importance and keeping all parameters stable is the goal. But if you had to pick one to call the "most" important, what would it be. Feel free to discuss your reasoning's for your choice.
I don’t know about you all but I’m really excited about taking my reef to the next level in 2018!
Few things I have planned to do in the next few weeks.
Reaquascaping with Fiji Rock
Removing a lot of sand and adding a more coarse grain
Begin the Triton Method
Add to my fish stock
What are some things you have planned?
These approaches are totally different, but I've seen all work incredibly well, I'm not saying anything against any of them. I think its an interesting question and I'd like to see what you guys think about it. Personally, I take the middle approach.
how much return flow are you aiming for?
With variable pumps, it seems like I am always aiming for higher flow. But I’m not sure I need 3000gph that my Vectra L1 can crank out. (I’m not counting losses in head pressure or elbows and such). Just trying to make a point.
I’ve heard everything from 2x tank size per hour to 10x tank size per hour to much higher. What say you? What’s your perfect return rate are you aiming for? How many times you trying to turn your tank over per hour?
Ok so a little bit of click bait there but all to often "it" becomes a reality for many reefers who travel. IT DOES HAPPEN and what is "it?" The "it" is something bad happening to your reef!
Honestly it seems that if something bad is going to happen it's going to happen while you are out of town and no matter what you do there is no perfect way to mitigate the potential disaster. My wife even makes comments about "how this only happens when your out of town." :/
BUT that doesn't mean that we don't do everything we can to make sure we have a plan or process in place just in case something goes wrong. The ATO quiets working, for some reason the lights are not coming on, the tank is cloudy, there is a leak, the return pump goes down, etc..
So this should be a great discussion and I would like to propose a few questions to you!
1. How do you know when something is going wrong? What do you have in place that would tell you something is not right?
2. Is there someone who you trust to handle the situation? A friend in the hobby, neighbor or family member?
3. Do you have a plan in place or a way to be able to walk someone through the issues that are taking place?
4. Whats the worse thing you have ever had happen while you were away?

I am trying to decide on a good battery back up unit for my tank and I am thinking about getting a ecotech battery backup, but I would have to buy an MP10 as well, which would make it quite expensive(~$400). Are there any better cheaper options or would it be best to just bite the bullet and buy the ecotech battery and pump?
Hello it's me again!
Back at you with another question to get your mind working and data flowing! This is something that is near and dear to my heart and that is commerce within our industry. Plain and simple, we want it to be better. We want to hold bad people accountable and to reward those that are good. We want people to be able to shop with confidence and have a variety of options when buying, selling and trading.
So that being said my question to you is this.
Is buying, selling and trading within our hobby where it needs to be or can we do better as a whole?

Hi! My name is Anton Post and I’m a 29 year old guy from the Netherlands that got into reef tanks three years ago. I’m currently keeping a Red Sea Reefer 525 that has been running since January 2016. I’m very honored to be featured in this month’s Reef of the Month article on R2R! I hope you enjoy the article and pictures. If you have any additional questions please feel free to ask in the tank thread!

Water Circulation and Flow Summary and Objectives:
I’m using the Maxspect Gyre to create a good circular flow in my tank. Before the XF250 I had an XF150 with the regular controller, and the XF250 with the advanced controller is definitely an upgrade. I have it running in a 10-60% random pattern which really creates a nice flow through the entire tank. My reefscape is fairly light which enables good water circulation, even in the bottom areas. I did also apply a Loc-Line double outlet on the standard Red Sea outlet to aim the water coming into the tank to where I want.
- Temp: 25-26 degrees Celsius
- pH: 8.0
- Specific gravity: 1.026-1.027
- NO3: 10-20
- Ca: 450
- Alk: 8.0
- Mg: 1600
- PO4: 0.20
Lighting Summary and Objectives:
I have chosen a hybrid light since this gives me the most flexibility in setting the light intensity and coloration. The fixture has 4x75w LED units and 4x80w T5 bulbs. For the T5’s I’m using ATI’s Coral Plus bulbs in all four slots. For the LED pads I’m only using the Royal Blue and Marine Blue channels. This combination of T5 and LED gives me a color scheme that I really enjoy. Also, corals thrive under these lights.
Photoperiod: 8:00 am until 23:30 PM. (See scheme for reference)
Filtration and Water Quality Summary and Objectives:
Since my reef is LPS, Zoanthus and Ricordea heavy, I try to keep at least some nitrates and phosphates in my tank for better growth. Additionally, I have some fish that eat quite slow so I tend to overfeed to give every tank inhabitant time to fill its belly properly. Luckily the nuisance algae are kept to a minimum, the only minor inconvenience is that I have to clean my glass every other day to get rid of the green layer that slowly builds up.
Calcium/Alkalinity/Magnesium Summary and Objectives:
Since I’m using the Balling Classic method, I always dose my Ca, Alk, and Mg in the same amounts, this keeps those three values very stable over time. I try to stick to recommended values for Ca and Alk (450/8), but I tend to keep the Mg a little higher (1600) since I’ve seen good results doing that (less nuisance algae, good coloration and polyp extension).

Tank Inhabitants— Corals:
I could list them, but I’ll leave the pictures to speak for themselves. My tank mostly has soft corals varying from LPS to zoa’s, softies and ricordea. I do have some SPS pieces but they are scarce and positioned on top of the reef to give them as much light and flow as possible. Also, since my nitrates and phosphates are relatively high, SPS won’t be as colorful as they could be in an ULN system.
Fun Friday Poll. Have you ever woken from a bad dream or nightmare and raced to the tank? What did you discover? Was it in fact just a bad dream or did you actually find a problem and it turns out it wasn't a dream at all. Share your stories, both good and bad!
A couple of months ago we did a poll on what folks do to control Coralline Algae in their systems. Another question often asked is how do I get Coralline Algae to grow? Let's take a look today at what you consider the most important factor in getting CA to grow. Feel free to discuss below.
Although it's difficult if not impossible to get fish to actually school in an aquarium (unless it is very, very large), some do tend to shoal to some degree. Thought it might be an interesting topic to discuss what your favorite shoaling fish is and what type of success have you had with them displaying the shoaling/grouping behavior.
Obviously the poll is not an all inclusive list so feel free to discuss a fish species you've had success with if not on the list.
I've been reefing for several years now and I think I have enough experience to begin questioning a few things in the hobby. Obviously from the title, I'm skeptical of hermit crabs being truly beneficial in a reef tank.
When I first started in the hobby my absolute favorite thing was my hermit crabs, I remember them bustling around in my empty tank (it was nearing the end of its cycle and I added some hermits to help clean up the cycle algae). I really enjoyed watching them eat the fish food and run around. I noticed that the algae on the sandbed and rocks was going away and I was really pleased that I had a good clean up crew (at the time it consisted of snails, hermits, and an emerald crab). I was a little worried that I kept finding seeing my hermits wearing my snail shells, but I assumed that the fragile snail had died and the hermit had helpfully scavenged the dead body and was using the shell. In the years to follow, I saw them eat anything that died in the tank and I noted they weren't at all picky. For this reason they are great to have around, they are awesome scavengers and they are pretty cool to see in the tank, they add a lot of life.
Later, when I ran into problems with algae, I added a few more hermits to the tank (my course of algae removal is: manual removal, replenish CUC, turn off lights), the remaining snails I had died (I knew by know that hermits ate snails but I figured that hermits were likely better, after all thats what I had been told) but I didn't see them eating any of the algae and by the time I turned the lights back on they had instead taken the chance to eat some of the LPS weakened from light depletion. I then went to my LFS and picked up a turbo snail, a few ceriths, an emerald crab and some margaritas and threw them in the tank and algae was finally eliminated. I saw that the hermits really hadn't done anything to help and had actually hurt the tank by eating the LPS.
Now my tank has only about 5 hermits in a 35 gallon reef, along with 5 nassarius, 1 turbo, 2 margaritas, and 2 ceriths. My hermits are always stomping on my poor zoanthids, causing them to close up to avoid the grabbing claws of the hermits, eating the food I try to give to my gobies and pistol shrimp, and forever tormenting my helpful snails as well. I no longer have an emerald crab in the tank, they always get too big and are in my sump now so when a bit of turf algae popped up in the tank two days ago I figured I'd let the hermits try to get it. It's still there now and I'm really considering giving them all to my LFS, I'm tired of them. Will there be any real repercussions from getting rid of them, after all, in my experience all they do is scavenge dead things and my nassarius are far better at that?
I'd love to see what the general consensus of their merit is so here is a poll, I'd love to hear about your experiences as well as if you've found that only certain species are acceptable (I've found that all hermits are bad, but maybe there are some I missed or you disagree with).
What do you use as a guideline for your stocking density? Is it a certain number per gallon? Is it a certain number of inches of fish per gallon? Is it based on the age and bio capacity of your tank? Or do you just wing it?
It's an age old question and often asked by new members getting in to the hobby. The old Rule of Thumb is 1" of fish per gallon of water. However, the obvious answer isn't so obvious! The true answer is much more complicated and harder to understand.
So what "rule" do you use, if any?
I recently ran across this video from Jake at Reef Builders and thought it would make a great topic! In all my years I’ve never heard of using a waterpik for any application in reefing but after seeing this it sparked my curiosity about what else a waterpik could be used for!
Do you use a waterpik for reefing and what other ways might you use one as a handy reefing tool?
