H2Ocean Compact ATO Auto Water Top Off/Up Pump System

I bought this for my marine fish tank and it saves you alot of time topping off you can just fill up your reserve compartment in your sump tank and you can forget about it for a week before it needs filling up again

Purchased in June 2021 and worked well until the pump gave up the ghost today. Until it broke it worked just fine keeping my tank at the desired level.I would have expected the pump to last longer than 18 months hence the 3 stars.

Works great for my 1000 litre marine reef tank with separate RO chamber in sump

Arrived quickly was smaller than expected but works brilliant some clever thought put into this device. Would happily recommend it to anyone.

Haven’t had the product a year and it’s constantly cutting out. Often flashes a red light for low water level but then doesn’t pull the water from the RO chamber. Pump is regularly cleaned but will often not work. Not reliable if you are leaving the tank for a few days away.

Reliable so far - easy to set up and comes with everything you need except a reservoir. Good quality kit.

After 1 month of use so far so good. Very simple design and very reliable. I have had once incident when it tried to overfill but the backup safety measures kicked in and saved the day.

I should have bought one of these to begin with. Has made my reef experience more pleasant - I was getting fed up with estimates of how much water I was loosing daily. This is consistent and far simpler.
