I have been keeping tropical fish for 49 years without a break, ranging to around 20 tanks (I had a fish house in the 70's), but never less than one. I thought I was reasonably adept at keeping fish, but after reading some of these posts, now realise I know very little about the science of water quality and plant growing. Just shows, you are never too old to learn.
Cheers everyone, and keep up the good work.
