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?
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.
How long it took your Nem to settle down to a spot?
From the moment it went from your plastic bag to your display tank to the moment it settles down and stay there "permanently".
I had a discussion maybe more of a disagreement with a fellow reefer.if he had the choice and the money what would he stock his tank with frags or grown out colonies?his choice would be colonies while mine was frags.again if money wasn't the issue what would you do?
I truly do enjoy watching something small grow into something I can be proud of.sure it's alot of work to get it to colony size but that's the cool part.i can say "I did that".
he on the other hand loves him a colony he can place in the display and fill a spot instantly.he's not a real patient guy so this fits him.
yes it's much cheaper to buy frags than whole colonies but doesn't it take alot of the fun out of it?
chime in and let me know how you feel,frag or colony?maybe show a before and after pic of your favorite frag to colony success story.everybody loves to see coral pics yes?
thanks for taking the time to read and hopefully reply to this thread with some pics as well.
So I had the idea to use a spare power head held in my hand to "blow" out any detritus from in and around the rocks in my fowlr tank. Worked like a charm. I was surprised how much crud got suspended in the water column only to get sucked up by the filter. Anyways, it's sorta like a leaf blower in the tank.
A topic that pops up every once in a while is the shimmer effect caused by a particular light or lighting type. What's your take on the shimmer effect? Do you like it and want to see it on your tank or do you find it distracting? Let's have some conversation. Feel free to share your results if you've tried a particular light or added supplemental lights to achieve it.
Yesterday we discussed stability. Many commented (and I agree) alkalinity is probably the most important of the parameters to maintain stability. (Yes salinity and temperature rank up there also).
We did a poll a while ago that asked what your average dKH measures in your systems. The vast majority of responses was in the range of 8.0-8.5 dKH. I thought it might be interesting to look at what your daily demand is in terms of dKH. Yes, this will vary from system to system and be determined by many factors. This poll is just to get a feel for the daily demands that we have to supplement for to maintain stability.
Yesterday's poll looked at preferred macro algae and chaeto was the overwhelming preference of those that participated. In second place, albeit a distant second place, was Caulerpa. The one negative thing I've always read about Caulerpa was the potential for sporulation (going sexual) and how invasive it can become - both in the refugium and in the display if it makes its way there.
So I'm curious if those that have used/tried Caulerpa have had an experience with Sporulation. If so, which species was it? Share your story for those considering using the macro algae as part of their nutrient control.
