LOL. Thanks Steve,
I've been working on getting my water quality better before I add any more coral or fish (really hard to do) and have learned a few things. I was doing frequent wc weekly for a while but my trates and phos were usually present. I got a Hanna Checker for the phos testing and an Elos for the trate testing so I could get accurate readings (was using Tetra and Nutri test kits). I got a biopellet reactor and some biopellets and they did a great job of bringing down the trats and phos and most of the algae died off, made a return, started to die off again and now is making a return. Turns out it's bryopsis.
My trates are at 0 according to the Elos test kit and the Hanna Checker got as low as 0.09. Supposedly, I am nitrogen limited and that's why the phos won't drop any more. It actually started to go up and the bryopsis returned. I've been adding nitrogen by Brightwell to get the biopellets (the bacteria actually) working again and bring down the phos. The more nitrogen I added, the more the phos went up. It went from 0.09 to 0.44 over the last 2 weeks and the bryopsis became stronger, gha returned and now I have a bunch of cyano and I haven't had that for over a year now. So much for adding nitrogen. You can see bubbles all over the cyano, gha and the bryopsis so it looks like its dieing but there is no reduction. I rearly feed flake, I made my own mush, and I'll feed mysis shrimp. I'll feed every other day and add green or purple algae in between feeding once or twice a week for the tangs (even though most of the fish will pick at it). I read that high levels of Mg will kill off the bryopsis so I raised the level to around 1750 and its been there for 2 weeks but I'm not seeing any change in the bryopsis. Found out later that you need to use Kent's Tech M magnesium (apparently, there is something else in there that kills the bryopsis) so I ordered some and hopefully it will be here today. This weekend I'm planning on doing some big wc and suck out as much cyano, gha, and ripped off bryopsis as I can, then slowly bring the Mg back up to a high level using Tech M and see what happens. If I can, I'll pull some of the rocks out, scrape off as much bryopsis as I can, then rinse it off with hydrogen peroxide (supposedly kills bryopsis but doesn't hurt the corals. I'll test it on a piece and see what happens).
Anyway, I think the biopellets work but not on bryopsis. Once I can get all of it out for good, any new piece of coral I get will be scrubbed, dipped, and maybe cut off the plug (throw the plug away) before the coral goes into the tank. My daughter and son in law are coming in for the weekend
)) so I'll probably only do the wc. I'll pull the rocks out later to give them a good scrubbing.
