perry, what bacteria do you dose and why are you dosing it? I missed that in the thread.
I use AF Pro Bio S at 2 drops daily. Post water change, I use Microbacter7 at 5 drops. Why? I am of a belief, with dry rock tanks, that this is a missing component for sps health. Tanks established with ocean rock seem to have copious amounts of bacteria readily available and flourishing. When I recently had issues with my tank, I pulled the bottle out and started dosing again, based on my observations, all issues slowly turned around. Is it necessary, heck no, but do I see better coloration, growth, PE, and overall health, why yes I do. I believe Anthony was on to someone with the thread, "why can't you keep sps " . I am no5 using a carbon source though, just not necessary, bacteria used as a food source(anecdotal) and to drive health and vitality.
