How much auto water change is TOO much?

[MaxtheCat]

Hello friends

We just got our auto water change all hooked up and have it set up to change 5 gallons per day on a 110 gallon tank. I was hoping to do more because our nitrates have been high but he thinks this is more than enough. What do you have for a daily water change amount, especially when you'd like to bring nitrates down?

What size is the tank? A 5 gallon water change on a 10g nano will have different results than on a 300 gallon tank.

Fixed it. Sorry I'm a banana head

Sounds like a good place to start and monitor the nitrates

I think that 1 to 2 gallons in the long run would be an appropriate amount, but 5 gallons in the short run doesn't seem unreasonable. Depending on what you have in the system and how sensitive it is, you may also want to add a weekly manual water change that is larger until you get back on track. Good luck!

Thank you! I think we were hoping to do automatic water changes as often as possible throughout the day so that we don't mess parameters up too much with doing manual changes. There is always such a swing with temp when we do larger manual ones!

That is a good plan. Not sure if you are familiar with the @ReefNewsNetwork podcast (definitely worth listening too!) - one of the hosts has an AWC system set up on his large tank and has talked about it in recent episodes.

**Maybe @JerSaint can remember which episode.

No, never heard of it but I will look for it right now! Can I ask what AWC means without being laughed at? Ha ha ha! Algae with coral??

No worries and no laughing! AWC = auto water change
