Dose pump...

Sleeperr34 · Jun 25, 2014

Ok so i have seen a few posts by people with a dose pump they use for auto water changes that has a two diff dose hoses running with one motor. I love the set up and have been planning on using a dose pump to do small amounts of constant water changes through the week. But was always worried about a normal one. Of getting 2 diff ones just because it just gives it an extra point of fail. But i can not find the pump anywhere that everyone else is using. Any help finding it would help greatly. Ty

Do what will make you happy.

I have a pretty easy set up on my tank for small auto water changes. I set this up every other week, approximately 25g each time. It works for my set up because of the way my sump is configured.

First off, I measured a 2 gallon fluctuation in my sump and set up my fresh water ATO float switch at the high with a low flow aqua lifter pump and a slightly lower about .25" float switch for saltwater on a maxi jet 600. I use a maxi jet 1200 on a timer to pump out about 1 gallon of water once per day, which is roughly about 7 seconds (takes some tweaking and measuring)

The water will come from ATO and New Saltwater before the entire 2 gallons are removed, but I have them dumping in at opposite end of sump. I expect very little if any new water gets removed during my process. I also believe that the amount of freshwater that makes it from the ATO is trace compared to how much faster the maxi jets work to remove and replenish the water. I find my salinity remains constant and pH/Alk stay pretty consistent as well.

Good luck finding what works for you!

This is interesting. Is there anyway you can show us how you did this? Pictures, video? For some of us that don't have, can't afford or no room for a fish room this sounds great! Where does the old water empty to?
