Red Sea Reefer integrated ATO swap out

[ajtomase]

I'm looking at either the Red Sea Reefer 625 or the 750 which come with an integrated ATO system and reservoir. Is there a way to remove the integrated ATO and switch it to a Tunze system instead and use an external reservoir instead? Is there instructions on how to change those items? I've been trying to find videos, but there's nothing. Thanks!

Does it have the ATO reservoir built into the back of the DT or a separate tank sitting on to of the sump? I have a RS Reefer 170 that had it sitting on top the sump. I swapped that ATO out for a larger tank and used a separate ATO controller.

I'm setting up a 625 right now and the reservoir is just a small tank that sits freely on top of the sump, even glides left or right if you want, with a line to the float valve in the return chamber, so yeah completely removable.
