My fish room is really my work study, but it’s got 4 tanks plus a 10 gal hospital tank. Problem is, my bedroom is between there and the bathroom, where I get water for changes.
I broke down and got a residential RO filter for the discus, but at 70y/o I don’t want to carry lots of 5 gallon buckets. My wife relented and said okay about the filter in the shower, which has 2 shower outlets, so I adapted one. I added 2 rain barrels—the flat backs allow two 50 gallon barrels side by side, so one is filtered and the other is waste, which I use for South and Central American cichlids.
The water from tanks goes out the window to the landscaping, and the fresh gets pumped out of one or the other barrel through a 50 foot hose to the appropriate tank…. That’s the hose coiled outside the shower.
Who needs filters? Just replace the water!
(I heard some parts of North Carolina got 30 inches of rain over 3 days, a few days ago.)
