My tank a 240, has 4 250watt 20K MH Lights and 4 T-5 54Watt actinic lights. I am not really happy with the light from the actinics. I was thinking about putting in some LED's but I have my lights about 12 inches off the water. I like it this way it gives me lots of room. Will LED lighs work this high off the water? -Steven

I am completely baffled by the upwards creeping salinity levels in my 20 long nano. I have had it running for 3 years and over that period of time the specific gravity has always crept up. I use a properly calibrated refractometer, top off with RODI, and regularly change water. I've asked around and no one has any idea what could be happening. Anyone here ever experience this?
