I cant believe how this stuff works! For the 5 bucks it costed me, nothing comes close. It got me down to 5ppm nitrates and if i was a dog, my tail would wiggle! Copepods are up, soon to come......... Mandarin!
I use it in my sump and 120g copepod tank. I switch out chaeto between tanks for mandarian. If u use chaeto, it needs nitrates and or phosphate to thrive. I over feed, so the chaeto helps me out alot. I got it at a lfs, on line has tons of it. You dont need much because it will grow very quickly!
