How to Handle Fish During Water Change Options

[volks]

Dear All,
searching the forum found that in general many bros change ~80-90% of water per time.
Where did you place the fishes during such change?
What about temperature different?
Could we leave the fishes in the tub and fill in fresh water from the tap?
Thanks

Dear All,

Thanks

yes i did that. i don take out the fish in glass tank.

My lazy man method:

Below is for tank with sump setup

Draining
i put a submerged pump into the main tank
Attached a hose to the submerged pump all the way to drainage pt in the tiolet. Run the pump, drainage is fast and furious
Fish still inside. once 80% of water is out, i stop and withdraw the submerged pump.

Filling Water
using the same hose again
i attach it to the tap in the tiolet and run the outlet end to my sump tank instead
in sump tank i premixed all anti chlorine/chlormine solution and fill up to almost full capacity before i activate the sump pump to pump the water back to the main tank.
Tap water will now run thru the sump before going to main until tank is filled up. Of course , fish will run the risk of chlorine exposure.

whole Process is 30min for draining 80% and topping a 4ft tank and i can do a parallel water change with green water tub. Total time: 40 mins bec of sharing of hoses. otherwise faster. no need tocarry heavy pails for main tank now or rely on siphon hose.

FIsh never leave main tank. the last i check they still swimming after 1 yr.

green water tank
for green water tank, i will confirm take out the fish first. method same as what happy buddha advocates.
