Auto water changes

[Doglips56]

I have approximately 115-120 total volume and want to set up auto water changes.
For this volume how much water should I change if I want to do small daily exchanges? I already have good nutrient export so it doesn’t need to be a massive amount

How often did you change your water before and how much did you change.
same totals but divide it up daily now. Probably about 30 gallons a month? if so maybe do 2 gallons a day.

Can you set up a system with a 1-5 gallon range. This way you could start out small at 1 gallon, test to your liking and increase if need be?

Not very consistent with water changes but everything is doing well just thought might be better if we started doing this

Yes. I’m using a jebao 4 head pump and will use one pump to remove water and another to replenish same time each day and my ATO is controlled by Hydros so can program it to shut off for that same timeframe. Pumps are fully programmable

On my 125g I change out around 2 gallons a day, which is roughly 1.5% so by the end of the week I’ve changed roughly 10%.

I wouldn’t think that the Jebao pumps would be good to put that much volume through. They will likely work to start with but I wouldn’t be surprised if the heads quickly wear out.

Hmmm. I haven’t really used it at all. I dose All For Reef with a Kaemor Bluetooth pump but it’s small amounts. I love that pump

I use several of the cheaper kamoer x1 pumps and some of the bubble magus ts1 pumps. For dosing both of them work really well, however I would not rely on either of them as a AWC pump. For my AWC I use an older masterflex pump.

I always aimed for roughly 1% daily, spread out to be slow and steady.

Spread out as in every 2 hours or 4x/day? What’s optimal?

Probably doesn’t matter much, but mine was 12 periods of 15 min each spread out over 24 h (using a Home Depot timer).

My 130g changes 2g a day using the DOS over 2 hours. It can run up to 50ft, so I have it piped right into my basement sink. I fill up my 50g drum once every 3 weeks and that’s it.

DOS heads are rated for 5000 hours so that’s 2500 days of water changes done for me for $300.
