Need A Good Top-off System

[svirid]

Good day,

I wanted to get top-off system one day and now its on sale for $79
brand is JBJ.
I am not sure that its a good one. Also do I need anything else to connect it ? I currently dont have any space near my tank so I was thinking to
drill wholes in the wall and setup the water container in the other room. Will I be able to extend this unit with tubes?
Also if I remove old salt water is that posible to fill up the tank with the fresh salt water using this ATO. If yes, how long will it tak to fill let say 10-20 Liters

Thank you very much.

Looks as though it comes with everything you need. You should be able to extend it through a wall. As for waterchanging with it... Dunno.

Good day,

I have setup JBJ top-off for a couple of days already but having some problems and questions.
I purchased it with the ext pump that gives 3.5gph but my problem is that when I connect everything
first of all water is dripping very slow, probably its a pump , does not have enough power to lift the water up but
thats fine I will change it. I am just trying to understand. I have to sensors one in tank one in the bucket, when the water
level drops it turns the pump on. In this mode I have red led light 1 and yellow led light pump ON.

but... after 2-3 minutes, RED led for sensor is still ON, yellow PUMP ON but not that bright (looks like inactive)
and pump stops working, water level is still down below its supposed to be.

Does anybody had anything like it?

Thank you very much.
