Did the 20 and the 55 on Friday. Did the 150 today and,will do the 135 later today after we get back from cutting Christmas trees.
I have 4 tanks, a 150, 135, 55 and a 20 long. It takes a good part of the day if I do them all in one day. I'd imagine if I had 10+ tanks that I would hAve to split them up over a couple days. But I guess it also depends on HOW you do your water changes. If you're only swapping water out it can be done quicker than if you're also doing filter maintenance, wiping down the inside glass, vacuuming the substrate, etc.I just did water changes on all my tanks. 10, 45 and 75 gallons.
And it made me wonder how people maintain 10+ large and stocked tanks. I would imagine it takes an entire day to do tank maintenance.
It's a No for me because I'm carbon dosing daily, my system is Nitrate free for life (as long as I'm still alive lol) until I stop dosing carbon? Still need to water change salt tho?
