Hi everyone, I am in the process of aquiring equipment to set up my new tank juwel rio 240, so far i have purchased a ex1200 external plus some siporax as don't like the bioballs (will leave them in if you suggest they would be better) to run alongside juwel filter would prefer 2 externals but lacking space for now, bought 2 reflectors, wave co2 regultor with solenoid, 6kg drinks co2 bottle (bubble counter and difusser suggestions please) and i have a jbl co2 test kit just need more 4dkh solution. I plan to run this as a long term aquascape once i am happy with it, i have been reading alot on here and others sites and am unable to decide what type of substrate to use cost is going to play a big factor in my decision and i am hoping to continue using easycarbo and profito which i have plenty of. Current tanks are black gravel and sera Floredepot. Water is also a big debate for me as tap is unreliable ph 7.0 - 8.0, no3 20-40+ppm, gh-20+. At the moment i am using hma from a friend, however for a short time could provide ro. My next small issue is the 2 tanks i am replacing 1 mine with neons and ancistrus, and partners has guppies (breeding nuisance). I have spoken to a few places including TGM who said they keep guppies in soft acidic water with no problems and they advised to use ada as amazonia 2, but cost could be a big issue slowly running out of budget i set myself. Plants i have not decided on, but have had reasonable success with P.Helferi unfortunately got a bit tall due to amazon blocking out light but i do fancy trying it again in addition to another carpet plant aswell, maybe some moss and java fern on wood and a mixture of stem plants to rear and crypts in between. Any help or advise will be gratefully received, only been in hobby for 10 months.
