Boss I had to decide on culpera or seagrass...and I got the culpera..BUT it has three different types. Im going to start running my sump on a reverse lighting sequence so the sump is lit when the main tank isnt. That way I dont get heat build up like I have been in my cabinet. I ordered 3 10000K and 2-6500K bulbs for my T5 setup on the fuge. those too were like pulling teeth to find. T5 NO bulbs are damn near impossible to find. Seagrass looks pretty bad ass.....but i heard it doesnt pull nutrients as readily as macro algaes. Anyways thought I would share the find.....ive been looking for it forever, wouldnt want the reasearch to go to waste.
