Automatic water change

[James butchart]

Hi everyone I'm looking for your taughts on auto water changes.

I'm going to start doing auto water changes and I'm not sure which is the best, 10-15% once a week or spread that out over the week or does it matter.

I change 1% of my system volume everyday spread out over 24 hours, it’s worked extremely well for me, the tank and corals love it as much as I do.

Good stuff thanks for the quick response. I was thinking that myself but wanted to make sure.

I'm doing 3% every day - which is intentionally excessive. But I'm still getting the tank set up (no inverts yet, let alone fish or coral), so my goal is to pull out some of the gunk in the water from the cycle. I'll drop it down to 1%/day as @Rick.45cal is doing once the tank is actually live.

I’ve had my tank for a few months. I do 5% 2-3 times a week. I’ve never had a problem with algae (other than a tiny diatom problem which was short-lasted). No ammonia, nitrite/nitrate spikes either. But I think 10-15 once a week is fine. Just check your parameters often in between.

I prefer to do manual water changes and I do 10% per week. I like to clean the rocks, vacuum the sand and occasionally vacuum the sump during water changes so automation isn't going to work.
