Thread: Bottom Drain Aeration - winter

Should I turn down or switch off aeration via my Bottom Drain in Winter? There is no other aeration.

All 3 BDs have aeration and I have run it religiously through the summer at a high output.

However as winter sets in and the water temperatures inevitably cool ( Im still at about 14 at the moment), would you reduce or even switch off the air supply ? I am not having issues like Hippo with an adverse vibration effecting the fish (as far as I know ), just wondering as to what was best practice ?

Thanks Very Much for the reply . In which case I shall experiment and continue to monitor behaviour and water quality to see if there is any effect.

I chave 2 Hi-Blows so easy to switch one off and I can 'throttle' supply as well quite easily.

For some it's fish behaviour. FREDDYBOY if he every turned his air off the fish would flick off the dome until he put it back on !
