Ok, here goes...I've had a phosphate problem for a couple of months now. I managed to keep the hair algae down with the help of some nice critters, but with the upgrade to MH with VHO supplementation, it's really starting to spread again. My origional phosphate reading was around 5ppm. It's down to 0.4ppm now with the addition of my refugium and new feeding schedule. For that last couple of ppm's, which phosphate remover should I go with? I'm looking at Kent phosphate sponge and the Seachem Phosguard. I've heard good things about both, and I really wanna get rid of this crap. thanks
