I have 2 tangs in there that are only about 2 inches, 1 Blue tang and one sailfin, + 3 little damsels about an inch big. And couple hermit crabs and turbo snails too(dont know if this increases nitrate).
The tank has been staying at 10ppm for several weeks now and I just cant get it to 0. And I measured the RO
water I'm using and its at 10ppm too. I'm careful about feeding so hopefully that won't raise the nitrates. Perhaps its the aquarium pharmaceuticals testing kit thats off? I'll try the LFS
and see if they can test it.
I want to get couple small 1"-2" corals as a start but don't want them to die right off the bat because of nitrates. Thanks you for the help, Hopefully I can find a way to reduce the nitrates!
