Changing PH In Tanks

I was wondering if those options would be the answer.    Time to start parking a tanker in the driveway then.

I think I may have to get more water containers anyway, but perhaps smaller and/or more frequent changes will be easier. I think I'll have to try a few scenarios and see what fits in with my schedule.

Even now I don't clean & perform water changes on all tanks on the same day, because it takes most of the day, so I've taken to doing 2 or 3 tanks each evening. I think I should be able to store enough water for that, which could also be used for one tank in an emergency. 

OMG littlefish You must have permanently wet arms, is it possible to get trench elbow?

All I do with them is wash under the tap to get rid of any dusty bits then put them in the tank. They float at first but sink after a few days.
When they get old, they lose bits so I try to remove them when I see the odd bit falling off. If left too long they disintegrate when you try to pick them up.

I've never had a fish get injured by doing this. I'd be worried about them disintegrating too quickly if they were boiled.
