On bulk reef supply they have 2 different smart ato and I don't know which one to get my tank is a 46 gallon tank and I have a sump but don't know how much that holds because I just bought them but why do they have 2 of these because the other one's don't have 2 different ones can anyone help me out with this

I have the Smart ATO on my 40 breeder with a 20 gallon sump https://www.bulkreefsupply.com/autoaqua-smart-ato-auto-top-off-system.html
The other one is a small version of that more for fitting into nano tanks or AIO tanks.

So which one is for a 46 gallon tank with a sump the more expensive one

I would do the one I linked for a larger tank. The other one is more for nanos and all in one aquariums where space is limited
