Your tank looks great. I love the black background. And the scape looks great, I'm interested to see how dosing you co2 works, I am looking into doing the same thing.
Thankyou Cashmere! Although liquid co2 doesn't make you're plants as 'fruitful' as pressurised, you still get good results. I had a bad bout with black beard algae when my easy carbo ran out but now I've re done the tank and started dosing again there's not even a smidgen of unwanted algae.
. I recommend it!
The trick is, keep the dosing consistent, and once you start try not to stop or you'll be in for trouble!
