Hi all Ithought I'd introduce myself and ask a question if thats ok. I am in the process of setting up a 69 gallon tank primarily for discus and wondered what would be the best set up for discus and plants. I have had a full dennerle set up in the past which was great for a couple of months then it all went pearshaped so I must get it right this time or I will suffer the wrath of my wife . I intend to use a eheim 2329 wet and dry thermo aquaponics co2 as I already have these. Any suggestions on substrate etc would be most welcome I was toying with using either seachem flourite or a sand based with something like tropica underneath. Any suggestions would be most gratefully recieved. Thanks Mark.
