Don’t forget that the op asked for opinion between AC and Tidal.
The OP already made their decision. lol
k, so I got a Tidal 35 for my 20 gallon and love it. I'm going to save up to buy a Tidal 75 now for my 55 gallon tank
It's not really that hard to only service the AC every few months, and not touch the impellers. Keep the bio-load (fish and plants) moderate to low.
Bingo!
My tanks look empty compared to yours, Tiger, hence why I can get away with the maintenance that I do. I also use probiotics to assist in keeping the sludge broken down. I haven't cleaned an impeller in years.....
