Oh, and I know there's quite a bioload in the 10 gallon right now, so I just did a 25% water change yesterday but the cyano is even worse today. I'll do another water change in a couple days.
I can't wait for the cycle to finish either! I'm having cyano issues in the frag tank and its getting all over the sponges and gorgs. I've been manually removing it, but its getting old. I'm ready to get the corals into the seahorse tank and away from the cyano. I honestly have no idea why the frag tank constantly has such cyano issues. I use all RO/DI water in there and I do frequent water changes. I would just use some Red Slime Remover, but I read that it can kill sponges. Not sure if that's true, but I'm not going to risk it.
Thanks! All very good points. I am currently overfeeding (trying to make sure all the new fish are eating), so I would blame that except that before I put these new fish in there, I barely fed that tank at all and I still had awful cyano and hair algae issues. I'm partial to thinking its a flow issue, but I have a Koralia 425 in there and the AC50 does about 200 gph. So that's 625 gph in a 10 gallon. Theoretically that should be enough but it just doesn't seem like that much. I wonder if the eggcrate frag racks disperse the flow too much or something.Well, really 3 things for Cynao:
1) Normal main source is feeding.
What exactly are you feeding? Too much?
The RODI is unlikely to be the cause, unless really old, and you have high phosphate water supply.
Note that new rocks and sand can slowly release phosphates as well. Uncommon though.
2) Water changes only are partially effective.
They work to dilute phosphate of course, but all depends on percentages.
Plus, Cyano can take in nutrients rapidly, before you do the next water change.
3) Flow matters.
It needs low flow regions to really grow well.
To solve it:
1) Reduce feeding if possible, and check ingredients.
2) Add GFO, to chemically eliminate it.
3) Check and adjust flow.
4) Stay on it. It takes time.
I have used Boyd Chemiclean in the past. It works well temporarily. No negative effect seen,
even on my sponges. (My sponges are hitch-hikers though, not fancy ornamentals)
But it only kills the Cyano. It does not fix the root of the problem.
In a few weeks, it will be back.
FYI: All that is easy to write, but not so easy to do.
I still have Cyano issues as well. Mostly from over feeding.
Well I had already decided to take the frag tank down when I decided to start this new build, because I don't want to maintain 3 tanks. 2 is definitely my limit before it seems like a job instead of a hobby. With 2 main tanks, I can put a magnetic frag rack into each and hold enough frags without needing the small frag tank.If it helps, Denzil put a GFO on his 10 gallon, now 20 gallon, and it took care of his cyano issues. Maybe it was lack of flow, because he doesn't feed much at all. And, he uses the BRS GFO calculator, so he only uses like maybe 1/4 media. Might be beneficial on the frag tank? That way you can keep a frag tank going, but not have so many issues? Just a thought.
I can go out and get some GFO. Can that just go in the AC50? I've never used GFO. I always run filter floss, ChemiPure Elite, and Purigen as my media.
The ChemiPure elite is a brand new bag that I put in when I did the thorough scrub down of this tank last Tuesday. I would think it would be helping if it contains GFO. I wasn't planning to go to the LFS again for a while but I guess I may have to decide to make a trip for GFO. When you say put it in a high flow area, can it just got in the AC50? I change the filter floss when I do water changes, so like once a week. Maybe I should change it more frequently or just take it out completely?Hmm. ChemiPure Elite contains Ferric Oxide.
So that should be helping.
But with those "all in one" type products, it is hard to say how much is in there.
Suggest putting some GFO in a small mesh bag, in a high flow area.
Should be safe. If worried, add a small amount, wait a few days, then add more.
Purigen only gets ammonia + nitrate.
Do you change your filter floss a lot?
If not, it could be part of the problem, not part of the solution.

I've got an API Reef Master kit that includes a phosphate test. I just don't use it much because it doesn't seem that reliable and its hard to tell the colors apart. I'll try that this evening though and see if I can get an idea of phosphates.I really have no idea on effectiveness of ChemiPure Elite. Not saying it is bad. Just never used it.
A brand new bag should be helping though, especially on a small aquarium like that.
Do you have any way of testing phosphates? If near Union City, I have a good tester you could borrow.
Should be fine in the AC50, assuming there is room.
Weekly filter floss changing should be ok. Lots of pros/cons on using floss in general. No real opinion either way.
Great information guys, thanks! I still just wish I knew where the phosphates were coming from in the first place (if that is in fact the cause). I've decided I'm probably making a trip down to Aquarium Concepts tomorrow because they ordered me a blue velvet nudibranch for the main tank (to eat flatworms), and it should come on their shipment tomorrow. They stock a ton of dry good so I'll either pick up some GFO or some Phosguard. I can also try going dark on the tank for a couple days. I'm getting frustrated because cyano is getting all over my gorgonians and my sponges.
I really would prefer not to run a reactor on the seahorse tank if I can manage. Its weird because I definitely overfeed the main tank that doesn't even have a skimmer with no real issues. I don't even bother to rinse the frozen food I put into the main tank and I know that introduces phosphates. The frag tank has just had this issue from the get go even before there were fish in it, so I feel like its something other than feeding. I'm not really sure. I'm just hoping the seahorse tank will be like the main tank and not have so many issues. I can always put some GFO or PhosGuard in the media rack of the seahorse tank if I start having problems. I built the media rack to have plenty of space in case I need to put in extra media. The seahorses are sensitive to high nitrates, but phosphates shouldn't bother them. I plan to do weekly water changes on that tank to make sure the nitrates never get too high and that should also help keep any phosphates in check.Idk, at this point, because of the bioload and the feeding requirements, for the health and safety of your corals, you may be better off running a smaller (if there is such a thing) GFO reactor. Who knows, with how dirty the sea horses are, you may want to run one as a preventative on the pony tank regardless. In my experience, a huge part of phosphates come from feeding, and you mentioned that you'd be feeding twice a day. Maybe better to be preventative on the pony tank rather than corrective due to their sensitivity?
Yep, it will be turned down really low.The MP10 won't be too much for the seahorses? I'm guessing you're going to pretty much have it turned almost all the way down?
