you rotten jammy sod. I cannot for the live of me get these to take on in my
tank. I have 30kg of live rock in a 40G tank with 4 powerheads for flow, 2x
actinic 36" tubes (marine blue) and a 150W MH. my sump has three chambers
of media, one with calerpa and a prizm skimmer. nitrates are a bit hard to
control but the other parameters are all within normal limits and the green
buttons refuse to open or even die off. they remain permanently closed.
What am I doing wrong. my tank dimensions are 36"x18"x15" with a
36"x15"x12" sump and a Rio 1700 return pump.
I am currently awaiting the arrival of a turboflotor skimmer to clear up the
debris and OR6500 return pump.

HELP.

Robin
