I have 100lbs of rock, 60 lbs was live rock been in tank for years 40lbs was reef rock that was put in back in Nov or Oct 2009. I have 4 fish in the tank 2 Green Chromis, Bicolor Pseudo, a maroon clown about 75 snails and a serpent starfish. I had Nitrate levels of 160ppm for a long time and now that I have gotten them to bounce between 2-5ppm I think my rock is leeching it out after soaking it up for so long. I think that is what is causing my Cyano
. So I bought a Phosban reactor and got some phosban even though Phosphates are reading 0 and I have another Phosban Reactor that will be here Monday or Tuesday that I am going to fill 3/4 way with Seachem's De-Nitrate. The plan is to fill it with tank water and some bactreria cut it off and let it sit for a week, let the bacteria multiply and then cut it on to a slow steady drip of about a drip a second. I like Seachem sorry! I donot have a fuge wish I had the room. I am thinking of getting about 40lbs more reef rock and break it up and slowly add it to my sump.
