Beautiful tanks! Lovely colours you got going there. Also doing liquid C at the moment. Was your co2 setup expensive ??
Hey weeza! what kind of co2 chemical additive do you use?, I had luck with flourish before my co2 set up.
We bought our Fluval 88 co2 set up for $115.00 and it's really easy to set up and I believe it's already making my plants look a lot healthier.
