I've had a few requests about my FSI canister sock filter. I am using a 100 micron felt and polypropylene sock filter in this canister by FSI. The loop is pumped by a blue-line 70hd pump and I have a 25watt UV by Aqua Ultraviolet on the return. There are two other closed loops - 1 has a fluidized bed filter with purigen and the other is a 3 or 4g Eheim canister with K1 media. There is also a constant drip. The picture of the dirty sock filter shows the first time that I changed it (after about 4 weeks). The bio load on this 300 is pretty heavy but this set up seems to be working well - the water is very clear. Lighting is 3 in-line programmable LED units by AI. The lightening storms might be a bit much but I love it - and the fish don't seem to mind!
