Using Polyp Lab System Reef-resh?

[littlesilvermax]

I am using it, for about 2 months now.

I would say mostly good things, able to get some faintly blue tips on an otherwise brown coral I have had for 4 years now.

I am getting some biofilm on some things though.

Overall for me the verdict is still out.

If you are having nitrate problems I would imagine there are other things that would solve it first.
