they could have bloat, that makes them look fat. :lol:
as for your algae...how old are your bulbs? if they are old then the plants aren't getting the right spectrum (or enough of it) and so they slow down. algae can use a lot of spectra. that was the only thing that wasn't covered. also using tweezers to pull off big clumps of the algae. i did all of these in a period of a month and i have minimal algae now.
or do i?
