Enlighten me, why do you turn the canisters off when doing water changes? The canister is pressurized so as soon as you turn it off everything becomes 'free' for want of a better word so when you turn them back on again it re-pressurizes and all the crap in there will be free to pump out straight back into the tankLoulou;1929748; said:Pectoral fins!!!Thank you!
Just finished a 50% water change... vacuumed only part of the gravel and everything was fine until I turned the canisters back on... that's where the water turned cloudy again...I am guessing the bacteria in the filters must have been pushed out...
You are entirely right. The reason I turn the canisters off is because of the intake tubes. I have drilled a hole at one point in each to insert suction cups that holds them to the glass. I normally turn the canisters off when the descending level of water during the change reaches near these holes - this is to avoid having the intake tubes sucking air through these holes.Yanbbrox;1929796; said:Enlighten me, why do you turn the canisters off when doing water changes?

I'm just about to do a 25% change on George's tank with an internal filter rinse, as soon as the powerhead goes back on the tank will be a mess but I can't get around this with the internal but an hour or so later it will be crystal clear again, all this time the canister will be left running

Mind you, I don't know for sure that the canisters would suck air through these holes - after all, I made then tight enough. Yet, I turn them off just as a precaution. Maybe I could try to leave them on during a water change to check whether they would really suck in air. If not, then my problem would be solved. If they do, I would have to find a way to make the intake tubes really airtight... with maybe some silicon.
In fact I have drilled the intake tubes for the cups... below is a picture showing these intakes (the tube in the middle is for the air lines)Yanbbrox;1930116; said:Still a bitCorrect me if I'm wrong: You've drilled holes in the tank for the cups that hold the pipe intakes for the canister, the intakes must be lower than the holes, tanks drain downwards(or at least they do on this side of the planet, I'm sure master Tequila's tanks are different
) so how can air get into the canister through the holes for the cup?
