Hi everyone , I hope someone can help me. My new waterbox penn 6225 was started with new live sand about a month ago. The rock and everything else came from my old tank and half the rock is new. The old rock had some sea lettuce which I was fine with as it would soak up excess nutrients so I thought.
The issue is at fist I had the ugly phase which seemed much lighter than normal. I cleaned the sand and everything looks great. But about 3 weeks later I still had some rusty look on the sand and the lettuce was growing. But now it seemed algea was going off the diatom. I have tried the last 2 week to syphon the sand but it comes back more.
Any ideas what to do. I would let it play out but I do not want it turning into a carpet and mess. I have been trying to clean like a mad man because the tank is beautiful. But this sand issue I can not seem to shake.
I have a funeral but algea has been scarce to find. Clean algea that is. So I could bump that up some.
Nitrates are 1 with nyos test kit and p04 is .06 with Hannah. I am changing socks and filter floss every 3 days. They literally turn brown and fill up.
