Sounds like you got it. pH is a little low but I wouldn't try and tweak it at this point. Might want to try and cool the tank off a couple degrees as well. The bioballs just wouldn't have provided much benefit over the LR and could eventually trap more detritus. Siphoning out those back chambers once in a while is a very good idea. When I had my cube, I was changing the floss pretty much every other day. I ended up using pillow stuffing (non-flame resistant polyester) from the fabric store. You can get a huge bag for a fraction of the price of aquarium filter floss. May also want to good inTank and checkout their media baskets and other cube accessories. Congrats again on the startup!
Are you spying on me.....because I visited InTank last night and checked out thier media basket. And I have been using pillow poly for years also. LOL
Working on the cooling issue. Think I have a hinky heater. Will swap it out with a spare if I have to. Although, I cannot hear a fan running....maybe I have a bad fan also. I also removed the small plastic tab between chamber1 and 2 and saw an immediate increase in flow to my drip basket. Much easier now to control the water level in chamber3.
I agree with your first thought that the LR may not be so live or certainly not so mature as first thought. I've yet to spot anything alive! (just some small patches of coraline algae).
I'm prepared to use all of my patience on this tank....... I'm not in any hurry to add livestock.
I think I like the refugium idea in Chamber 2.
I will be working on that DIY aspect.
Way down the road, I will eventually setup my 36" wide with a ten gallon refugium/sump.
