cheers phrog. I'm more of a bro-ette than a bro but I'll take what I can get
If you want any tips I'm happy to help if you pm or something. The waterfall setup is real simple, I just took that cheap indoor fountain pump set and put extra tube on it, ran the tube under and behind and over the rockwork and Bob's your uncle. The head on the fountain is 50cm so it needed no work at all. Then I put a filter sponge in front of the intake and surrounded it with rocks. You get quite a lot of nutrient uptake from all the plants so no other filter needed. Or that was my experience in their previous tank.
I'm thinking of putting some height into the scenery with a creeping fig (Ficus pumila) and some twigs. All the plants are baby houseplants from the red shed so I probably spent less than $80 for everything.
