It's not leaking, in case the title was misleading... So my current schedule still allows me time to maintain my tank but it has not quite let me do the work needed putting together my new tank, so for now (maybe for a while) I'm still forced to put up with this thing, but I refuse to give up on it because I love my livestock to death and will do everything within this tank's limit to keep them all happy I'm wondering if I can turn the crappy built in sump/filter into a mini-fuge, I'm thinking of throwing 6-10 6500k Cree LEDs on a mini heatsink on top of this chamber where I'm keeping LR, the water circulation is quite ideal, a pump lifts the water out of the tank & sprays it via spray bar over the entire length of the chamber, inside there are 2 slotted baffles before the water is returned to the tank which I assume will work perfectly for keeping chaeto in place. Also I have the skimmer setup so that it also lifts water from the tank & then returns into the soon to be "fuge" area. Do you guys thing this will work ok? if so would anyone in the east bay be willing to donate a clump? To those who know my tank well and wondering why I'm doing this, well I'm SICK of algae, I don't have a bad infestation or anything but there's always some fuzz on the powerheads & frag rack so I want it gone, also I want to ditch carbon dosing (if I can). Pic so you know just what the heck I'm talking about, there is only LR in there right now; Another important thing I should point out is this is on top of the tank so the main lighting for the tank actually hits this thing too, could chaeto die from overexposure to light? it would end up getting a very long light cycle between the fuge lights and main lighting. Could I possibly do a short (maybe 4 hours) light cycle for the fuge to offset this?
