To cut a super long story super short, I have a brand spankin' new tank just waiting for me to transfer the substrate and media to, and my poor loaches. I've lost half my yoyos in this latest drama. New tank measures 120x50x40. It has a power head, which I have never used before. The instructions are in very choppy English and it says something about a wet/dry filter, which I also know nothing about. Google has revealed little info on this tank unfortunately. It's an aqua nova, 240L or 63g. It seems much bigger than my old one. Tomorrow is the transfer day, so pics will come. I think this tank is mainly going to be loaches and angels. So very exciting!
