    More mystery critters

    OK, you guys did great ID-ing the pineapple sponges. Who wants to tell me what this is?

    Cyanobacteria, ugh.

    OK here’s a long overdue follow up... I’ve had to re-dose the CyanoRX a couple of times when the purple came back even a little. Finally, at the recommendation of an expert I vacuumed the sand, blacked out the tank for three days, didn’t feed and dosed with CyanoRX. That knocked it down really well, and followed by a large-ish water change it stayed clean for a couple of weeks before the pink started to come back. The theory is that I have a water quality issue. I have since increased my water changes in both volume and frequency, and have been paying closer attention to nitrates. Phosphates have been just about zero, but as we know that might just mean that they’re being bound up elsewhere. I have a new (better) RO/DI unit and today (a week after my last water change) the nitrates were 25. We’ll see how they look after a change tomorrow. Thanks for the support.

    It’s still gone for now. I hate skipping feedings, they always seem so hungry, We’re on vacation this week, so they’re on flakes from an automatic feeder. I put socks back in the sump to catch the excess, but who knows what I’ll come back to.

    Mystery critters, what are they?

    Awesome! I can use all of the help that I can get with nutrient removal. Thanks for helping to ID these guys.

    Cool. Thanks. Does anything eat them? I assume I don’t want them in the display tank.
  6. These little white things have been growing in my sump. Anybody recognize them? They aren’t in the display tank AFAIK, and appear to be harmless other than the fact that they are multiplying slowly. Cause for concern? Celebration? What the heck are they.

    Cyanobacteria, ugh.

    Well, they’re baaaaack... Actually they were back. I hit them with the CyanoR/X and knocked them down again. That was last week. I’m afraid that my nutrient removal is inadequate. I don’t think I feed them too much (once per day, a 1/4x1/2x1/8” chunk of LRS Fish Frenzy) but my skimmer doesn’t seem to be removing anything. It doesn’t seem to want to produce foam. It’ll make wet bubbles but the result is almost completely clear. I can catch stuff in filter socks which I can return to, but that defeats the purpose of the skimmer, no? Even those don’t seem to stop the cyano. As promised I took a picture this time. I didn’t want to let it get too far so this isn’t nearly as purple as it got the last time.

    LOL, it never occurred to me to post a picture of clean sand I didn't take a "before" picture. I'll try to remember for future threads, though I hope I don't have to repeat this process any time soon.

    Just a follow up. It’s been a few weeks and the tank is still looking great. No problems with livestock. Chems are all looking fine. Thanks again to all for the advice.

    Cyanobacteria, ugh.

    Good to hear. Does anyone here know why the water change right after treatment is called for? Obviously the antibiotic isn't harmful to the occupants of the tank, and it kills the Cyanobacteria, yet what I've read says to do a large water change right after the treatment. Just wondering why.
  11. John Freas

    Cyanobacteria, ugh.

    Well things are looking really good 48 hours in. No live Cyano anywhere that I can see. Some brownish patches that look like dead bacteria but the rest is nowhere to be seen. Hurray! Thanks to all for the advice. Tomorrow will be the 25% water change. I hope there’s no harm in waiting an extra half day, it’s too late to do it tonight.

    Cyanobacteria, ugh.

    I gave it the first dose of Cyano RX Sunday afternoon. By the morning things looked a lot better. There was still some hanging around though, so we'll see what this afternoon looks like. I may need to do a water change and re-dose.
  13. John Freas

    Cyanobacteria, ugh.

    Fair point there. I'm going by descriptions on the internet so... This is a magenta colored substance that is covering my sand, and now some of my rocks . It started out looking like a coloration to the sand, kind of the way coraline colors rocks, but after awhile it got thicker and if left in place it forms a wispy looking dark film on the sand which then begins to creep up the sides of the tank. When scraped or moved at all it turns out to be very thin and condenses into small strands which are fairly heavy and don't float in the water column very long without a lot of water movement. It's difficult to vacuum up because of this "weight". After stirring or siphoning the sand it looks clean except for where these strands land, but within a day it begins to pink up again and spreads rapidly over the sand within a week. I could take a picture, but I'm not sure how easy it is to ID from a photo on the internet.

    Sorry to hear about your corals! OK. I'm looking for an actual cure. Had I realized what this was at the beginning the Peroxide would likely have worked great, but at this point? I don't have any coral (FOWLR for the moment), so no issues with that either way. I'll dump the sand, it's not a big deal. Thanks.

    Does the H2O2 require a post-use water change like the antibiotic treatments do? Any other special handling/considerations? I'm thinking I might like to try this first.
