My snails didn't touch bryopsis. I have Astrea, a couple mexican turbo's, Nerite, cerith. My snail population was depleted after housing a puffer for the last few months. When I started seeing the algae bloom I added more quickly. I think you need the snails before it takes form, they keep the rocks clean so it has no place to grow. I got rid of my puffer and replenished snails. I have plenty of snails now, but they have nothing to eat.

I think high mag definitely keeps the tank looking cleaner. I wonder how high we can run without having an effect on corals, i'll find out. If it didn't bleach coral I would run it this high all the time.

Thanks, that's good to know the effect that high Mg levels can possibly have on coral.

I believe I have seen Pacific Turbo Snails sometimes eat young Bryopsis. Smaller PT snails are sometimes available that don't move rock like their jumbo size parents.

I have no personal experience but someone might also chime in saying that Trochus Snails eat Bryopsis.

What I know for sure is that when there are "sufficient numbers" of Snails (Astrea, Margarita, Cerith, etc.), nuisance algae never gets out of control. It may grow in a tiny patch but that's where some individual attention from Hermits can help, or where the hobbyist re-positions the rock so herbivores can find it easier.

The question might be asked, What is meant by "sufficient numbers" of snails?

- For a new tank, one per gallon might be the number as the algae eats the extra nutrients available when the biofiltration is not yet fully balanced leaving opportunistic algae to grow like crazy.

- For a tank with an algae bloom already in progress, the number might be three or more Snails per gallon. See this story of the Long Green Haired Mermaid.

- For an established mature tank over a year in age, the number of Snails needed may lessen to below one per gallon.

Aloha,

Mark

Did you do it to combat an algae problem? How did it work out? I was impressed with the results, although it did require manual removal, but never grew back.

Yeah I had bryopsis or some form of it on a couple frags. I had to remove all that I could and then it stayed away. Although now that I'm bringing the mag back down I have seen a few things again so I think I will just manually remove it instead. I didn't have a ton or anything just didn't want it to get out of control.]]> Mon, 23 May 2016 23:22:24 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=80108&PID=613142&title=high-mag-bleaching-corals#613142 <![CDATA[High Mag bleaching corals : bstuver wrote:I just recently...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=80108&PID=613121&title=high-mag-bleaching-corals#613121 Author: Chevmaro

Yup, still using poly filter. Don't know when or if I will quit using it. It doesn't help that some of my T5 bulbs started flickering, not starting, 9 month old bulbs. I had to replace 4 of 6 bulbs at the same time, put in some ATI bulbs. I'm sure this isn't helping, but the bleaching started before that. I'll start frequent carbon changes and bring mag back down slowly since all the algae is gone. See if that fixes it. If it is light related, the leather certainly loves it, it's getting bigger by the day.]]> Mon, 23 May 2016 15:56:55 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=80108&PID=613120&title=high-mag-bleaching-corals#613120 <![CDATA[High Mag bleaching corals : I just recently did the same thing...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=80108&PID=613115&title=high-mag-bleaching-corals#613115 Author: bstuver

Ahh yes, I remember that.

Here are some random possibilities.

Has Poly-Filter been used continuously since then? or when was the last time? The pollution exuded from this LR can slowly build up to toxic levels.

My next thought was lighting. What comes to mind is the yellow-green pigments that algae releases into the water. The reduction of algae probably reduced the pigments. The AC then could more easily clarify the water and more light reaching them could have caused the coral to bleach.

Couple this with the change to the environment when nuisance algae, even zooxanthellae algae, dies and then disappears, just about anything could happen.

What a challenging hobby. Smile

Aloha,

Mark

Dry rock, we know it was a culprit to a lot of issue. We had a lengthy discussion here:

http://utahreefs.com/forum/forum_posts.asp?TID=77994&title=what-kind-of-algae-is-this

The rock is appearing healthy now. Hard to see in the pic but it has came to life. I also took some rock out and spread them out a bit more for better flow around the rocks.

I scrubbed the rocks in old water when I did a water change. They weren't rinsed, but put back in the tank. I typically run 2 cups of carbon, it's a 55 gallon, but only change monthly. I'll try freshening that up.

I feel like the last 9 months since setting up this tank have been more troublesome than most reefers go through. Where i'm at right now, is the first time I haven't felt like giving it up. Things are looking good compared to where I have been. I don't have a lot of corals, I stopped adding things when I had problems. I'm going to start stuffing it as soon as I get this bleaching problem fixed.

Here is a pic of what it looks like today for reference.
