At present I have a 55gal tank that is in a one piece cabinet that has
47" clearance end to end.A full 4 foot tube with endcaps will not fit. I am currently running two URI aquasun 46 1/2" bulbs for a total of 220W.
I am not all that happy with the results, I get decent growth but at present no pearling. When I do a water change I notice a bit of pearling but that is when the water is at half depth.
I have done a fair bit of reading on the ODND setup and was wondering if you think I would be better of changing over?
If I do change do you think I should change what would be my best bet for bulbs? 36"?? or??
Just remember a full four foot bulb will not fit into my setup.
My Parameters are KH=4 GH=8, CO2 with a controller PH 6.8, 12 hour photo-period, dose TMG, K, FE, KH2PO4, Magnesium Sulfate,Potassium nitrate( all according to Chuck Gadds calculator)
