Auto water change.

[TeddyM]

What are people using for automatic water change device besides apex dos?

A dual channel variable speed lab grade peristaltic pump. Look for used equipment, with replaceable tubing. The roller heads also last a lot longer than consumer versions do. This one is a Masterflex and one of the best brands, though new they can cost a fortune.

Thanks for the info.

I also prefer using a lab grade tubing, which while more expensive they have chemically resistant linings and are optimized for long wear. You can sometimes find deals on larger quantities, which I did and will last me years.

If you are doing under 2 gallons a day the DOS will work fine. I use a DOS to do water changes on my QT system, they do 13 gal a day. If you are doing more than 2 gallons you will want something faster so its not running (loudly) all day.

I use this Kamoer system and it works great. My only complaint is you cant make it add a different volume than it removes, which is something most people wont need) This one is currently doing 4 gallons a day.

Ive had it running over a 18 months now and I have no complaints. As long as you calibrate them like once a year they are great. I dont have any issues maintaining salinity.

I love them and if you can set one up DO IT.
