It sounds kinda like your set up is a little touchy in the water lvl dept but I wouldn't think it would. Pothos is pretty cool plant. My wife was slowly torturing one in the living room it had a couple leaves left alive, a lot of the vines were shriveled it was mostly dead. I cut the good ( not shriveled) parts of the vine off stuck them in an overhead sump I set up on the 75 and they started sprouting leaves again and growing roots! I wouldn't call it a beast yet but its growing great. Obviously I didn't see a lot of nitrate reduction in the beginning but now that its established its sucking them up! I'm sure a plant that is doing well at the start will probably give you a better result quicker.
Ive always been told that any real uv is better then none I don't know if petsmart uv counts as real or not. I had a big aqua uv on my salt system going into the clown racks I had set up, it was all plumbed together with the main system and I thought that the babies could benefit from the added protection. ?? all I know is it didn't hurt and I had cheep florescent lights on the racks and no algae on the glass .
