Right, as some of you probably know I'm gradually planning my main tank, so when I get things sorted (in the next 10,000 years) I can actually set it up and it should run smoothly. The thing thats getting me at the moment is substrate. I just cant choose, but I hoped if I posted some things that I need out of it, you guys would be able to help. The only things I'm not doing is using 'normal' sand, like playpit etc, or spending 20 gazilion pounds on an ADA substrate. Fair enough ADA stuff might be great but I'm not into the whole get it just because its ADA! Not sure on the depth to go for but the tank measures 79"x24". Requirements: I really like black substrates but this often causes some strains of Discus to 'pepper'. I need to research that a bit more but as far as asthetics go I really like it. It could be a winner! I'd like it to be fine-ish but not sand, as its a pain to keep clean. If its cheap that will be a bonus. If I have to pay out Â£250 for eco-complete then I do, but the tank wont be broken down often for obvious reasons. If the substrate looses its 'fertility' or whatever you want to call it after so long then thats tough...lol I dont have any problems using a 'plain' substrate but I'd really like some suggestions for something underneath that will help the plants, if thats going to be the way to go. Sorry for all my random posts and questions :?
