DOS awc Longevity

[Mrx7899]

Just set up a dos for auto water changes. I m changing 3.5 gallons a day on my 225 which is about 25 gallons a week. I was wondering how well they are holding up to continuous use. How much you are changing a day and how long you have had it set up for. Side note auto water changes are one of the best things I've ever done.

Been changing 2 gallons a day for 2 years. I calibrate the dos monthly and I replace the tubing about every 6 months.

I plan on changing the heads at least once a year. 2 years is a good amount of time.
