No sump, no skimmer. Just a c3 and c4 filter. A korailia nano for extra flow. Right now im using calcium nitrate pellets that i bought in bulk. I plan on finding something to use for adding phosphate because im readyfor these plant to boom. Right now phosphate is my limiting nutrient. I havent had it detectable since i added my first plants.
Oh and Dave from kees gave me a really cool macro algae that hitch hiked in on a frag, looked super cool then I took it home and when the blue lights come on it also fluoresces red. Got a few pieces of it so I hope i can get it to grow in nicely.
