thanks guys. well theres no livestock other than plants at the moment. the tank is in its cycle phase during which im also planting stuff.
ive ordered a few more bits including a bubble counter, double check valves and a co2 atomiser.
the guy at my lfs did raise some interesting questions though. it seemed to think that co2 could be a bad idea in a tank like the fluval edge 46 due to the lack of space for it to escape out of. kinda weird because i figured thats exactly what id want. the long it stays in the better. to counter that though i suppsoe a ph controller would be in order?
what do you think?
