Hi,
I've got macro algae in a 125g marine tank that seem to flourish at 5" depth, but not to the same extent at 18-20". Would this seemingly minor difference in depth be a factor in the differing growth rates? My Chondrus crispus seems okay at either depth, but Ulva lactuca, seems finicky (which seems odd, given its reputation..) when it comes to depth.
My lighting is in the form of two 36" F30T8 "Natural Daylight" Fluorescent tubes (don't know the actual wattage) placed end-to-end over the tank for 8 hours a day.
Do I need to drag out a Secchi disk and check for water clarity???
Any information, or experiences greatly appreciated..
Cheers,
RAS
