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).
How many of you have said or thought this? "I can't wait for this reef to mature!" How many of you are still waiting years later? Sometimes it manures instead of matures. HA!
I started thinking about this statement and question and it got me wondering what the definition of a "mature" reef tank is. Does mature mean corals are growing out of the water and you have to prune them every week? Or is it mature when you can keep acropora successfully? Or is your tank mature when you can grow coralline, or keep clams, or house mandarins? What is it!!
What do you consider a "mature" reef tank to be?

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?
Here is the video and the article:
quick question my sand gets pretty dirty, and I like to stir it up a bit every few days. I also like to vacuum very good during my weekly water changes.
I have lost quite a few fish lately with no signs or visible issues with them at all.
Could stirring the sand be causing a problem??
I’ve tried to do research but can’t seem to get a definitive answer. I look forward to the debate that will follow. Thanks in advance!
Tell us the months you are most active in reefing and why this is!
You can choose multiple months on the poll!

So I thought this topic would make a great discussion for us!
I've never been one to "black out" my tank. I've tried it a couple of times for a couple different reasons but never stuck with it. To be honest I've not been a huge believer in it. Sorry and maybe that's changing!
That being said for the past couple months I have had an outbreak of a green algae, not hair, not slime or anything like that but a really dark green algae that doesn't cover corals but covers the rocks and sand. Tried a couple different algae "medications" to no avail.
It also blows right off with a turkey baster and blows into a ton of tiny particles but comes right back. Here is my thread: https://www.reef2reef.com/threads/green-cyano-type-algae.527256/
Here is the algae under a microscope:
This photo was taken well over a month ago and it has only gotten a lot worse since! The algae is actually way more green than the photo shows.
Ok fast forward to last Sunday. I arrived home from the Fl Frag Swap, great show btw, and my in-line frag tank was totally covered in this algae and just being overrun. So I decided to try lights out! I also decided to buy a new cleanup crew but until they arrived I would try lights out.
Yesterday, Wednesday, I checked the frag tank and the tank was clear! Like totally clear. So I turned the lights back on schedule for the frag tank and turned the lights OFF for the main display to see what would happen.
Today, one day later, the main tank looks a ton better with the algae started to release on it's on.
Check out the video:
Then I noticed that the skimmer was producing some really nasty GREEN waste see the video!
So I am not sure how all this will end but it did get me to thinking that maybe there is more to this "lights out" on algae theory, or at least certain types of algae. Which leads me to my question for you.
Have you ever tried the "lights out" or "black out" method and did it work for you?
This thread is two-fold!
1. Have you seen this amazing tank?
2. How do you feel about plants growing above the water line and have you ever tried it?
ENJOY this reef from Garrett Morizio!
I was using clothe socks, but I was thinking of giving the mesh a try. What do you all think?
Where do you fall on the spectrum of more testing, automation, and “helicopter parenting” your tank? Reef and fish.
Personally, I don’t really test much, I’m pretty laid back and let “nature take its course.” I do my water changes, and that’s about it. I nitrate test and water change about once a month. Sometimes I dose two part, but as unscientific as my dosing is I figure I’m better off not doing anything. I overskim immensely (but also overstock my fish immensely). I have ample light, and check salinity once per month. Nothing is automated, not even ATO (but that may change soon).
Of course, I don’t keep difficult coral. Hammer, frogspawn, torch, zoanthid, other polyps, leathers like devils hand, cabbage coral, and toadstool, mushrooms, star polyps, yellow polyps, xenia, anthelia, candy cane, sometimes a monti cap or two, and at one time a bubble coral is really about it. I have kept clams for a good amount of time this way, and bubble tip anemones. So, I realize I’m not dabbling in “needy coral”, either.
As far as fish, I quarantine and prophylacticly treat everything properly.
I’d love to see tank pics by those that automate and test frequently, and those more like me!
So what’s better?
Ok I have spent the last many months researching zoa pox 24/7 and have come up empty handed. WHAT IS IT? Seems like I know nothing about it. Everyone says Furan 2 works for this but does it really? I've tried it plenty of times with no success. ESPECIALLY on highend zoas.
There are many products available on the market offering supplemental nutrition to our fishes and other inhabitants. I'm curious how popular they are with R2R members that are using them on a regular basis (not just when you have or see an issue or as part of a disease treatment).
Please discuss your theories/methods/products below.
Curious how many reefers are actually making their own of fish food. Could be a blend of prepackaged foods or a mixture of "raw" ingredients that you've come up with. I guess I'm too lazy so as I just use a combination of foods.
Feel free to share your recipe with others.
