Well, I've removed the other fish. Fortunately, I have redundant filtration, and use sponge filters in all my aquariums, and have a spare eheim. So I took 1/3 media from the other 2, switched the sponge filter out for the fresh one, and some of the water, and the new tank has a head start. Regarding NL Spectrum Fish Food, I've had some for a while, and feed my fish part flakes, part spectrum. The fish eat the run-of-the mill flakes OK, but will fight over the spectrum.. Whenever I get new fish, they get the antiparasitic food mainly for 3-5 days. Once I'm done with the flake food, I'm going mainly Spectrum and Hikari. Regarding blood worms, the fish will only get Hikarui about 1x every other week. I stay away from fresh BL. Diet is a major part af what I consider a fairly succeful hobby considering I've been at it for approx 7 months. I have a question, maybe something good will come from this. Is there a forum just on diet? So now I thoght I was going to reduce to 4 tanks, but I'm back to 5: 47G Bow; 29G; 28G Bow, 10G; 2.5 G and I have a 47G Tall in storage. I dont know what fish for there. Hmm, I'm thinkng rainbowfish and a couple silver dollars. and It'll be planted of course, like all my tanks ( I know, silver dollars tear plants up, but I've seen a few cases when brougt up surrounded by them, they adapt); All my tanks are planted; The 47, 29, 10 have CO2. I just set up compressed CO2 for the 47. 5lb tank, Custom Electronic regulator (no solenoid!), PH Regulator with probe, diffuser with Rio 50PH, all on timer. Purchased from aquariumplants.com. A HEFTY price! But they offer a 3 year warranty, and the cylinders are the cheapest! Question: any good tips on a great filter for a 2.5 PLanted Eclipse, an a small CO2 setup?
