thanks for the link.Personally I would get a phosphate test before I got a phosphate remover. If your levels are high, then get some Rowaphos. That stuff is awesome. That is where I'd start.
If you have more than one tank, what is different about this one? Is it overstocked, the fish over fed,or get sunlight, or have the lights on longer. Getting to the root of the problem will fix it permanently. But then again, there is nothing wrong or will hurt anything if phosphate is the problem and you need to use a phosphate remover.
this is actually my least stocked tank and i almost never turn the lights on except sometimes when i want to watch them. i feed them what they'll eat, nothing gets missed, i don't even feed them every day. the tank gets zero direct sun and very little indirect sun, just what peeks through the gaps in my blinds.
