MickS77 Posted September 9, 2020 Share Posted September 9, 2020 Obviously inspired by Deans fry system, mine is also a 20 long. Water is pumped up using an MJ1200 with a co-op prefilter. I also have two sponge filters and a bag of co-op biomedia. With winter coming and being in my basement I want to add lids to hold in heat and evaporation. I made the lids using a single sheet of Lexan cut to fit over each tray with a lift off lid. To cover end space on the ends I used 1/4 thick acrylic, which I ripped with my table saw and a fine toothed blade. I installed a 1/2 bulkhead, for a cleaner look, to run the water through the cover from the pump I used rubber grommets to run the air and water through the cover into each tray. I used a piece of rigid airline tubing to go through each grommet. Blue tubing is water, clear is air. I'm pretty happy with the end result. I think using blue tubing for the water will help keep it cleaner. I'll switch it to co-op black tubing if I still get algae growing in it. I also like to think the evaporation on the lids helps the fry too, subduing the lighting, reducing stress. Currently I'm raising 50-ish Black Neon Tetra fry in one of the trays. e 6 Link to comment Share on other sites More sharing options...
