Just hook up a hose and treat the the entire tank volume with conditioner. Im don't understand why you cant add the water then treat it. Doing that many water changes at that interval will stress the fish. You can get a python and not have to lug buckets around. As stated earlier in this thread that is only 21-30% weekly. Depending on your nitrate levels and stock id say that would be bare minimum. I do 50% weekly on my 75g malawi tank and the nitrates still almost get to 20ppm with excellent filtration.
