I'd appreciate thoughts. My tank is the 240 litre Fluval Roma and I use pressurised CO2 via a Neo diffuser. The filter is a Fluval 406 which has a 1450 lph output. I've added a Hydor Koralia 1600 lph powerhead at the other end, positioned above the CO2 diffuser, which seems to circulate the bubbles around the tank much more evenly. So together there is over 10x flow (if the ratings are to be believed...).
Is it best to:
(a) Have the powerhead on only when CO2 is being diffused (starts 2 hours before photoperiod, and ends 2 hours before lights off)
(b) Have it on during CO2 AND while lights stay on
(c) Have it on 24 hours a day?
Just thinking the fish might appreciate the break and also perhaps extend the life of the Koralia (and save electricity!)
Thanks in advance.
