This item is fantastic and very easy to set up, I would highly recommend this Auto top up.

I have been looking at these for a while, but carried on struggling with multiple containers changing 30litres a week out my aquarium, which was not really much on a 850litre system.
I opted for the larger reef float as I want to do bigger water changes I could, and this did not disappoint.
I underestimated the weight of 100litres but that was my error ha! But once all hooked up next to the tank an absolute breeze.
Great bit of Kit, I really do recommend.
It certainly takes the chore out of the needed water changing.

This is my second AWC from Reefloat, I started with a Nano 5 years ago which is still going strong and with a bigger tank on the way the first thing I bought was a new, bigger Reefloat. Great product, great company, very helpful with any issues. Highly recommend.

Debated purchasing this for a few months before finally pulling the trigger, about halfway through first use I realised how much time id been wasting doing "normal" water changes.

Weigh out salt, mix it in, drop pipes into tank press play and come back in 4 hours.

No shock to the tank params, no faffing around disabling pumps/skimmers.. just set and forget.

10/10 would/am recommending to everyone I know with a tank

Love these water changers had one years ago and loved it so had to get another when i started up again highly reccormend them and gorden customer servis exerlent .

Couldn't be happier with this, no more turning everything off, using multiple buckets and a siphon hose. Recommend this to every reefer!

As always Gordon super helpful and fast delivery even over the Jubilee weekend 5⭐️

Simple controls, easy to operate. Just fill it, pop the two pipes in the tank and plug it in.

Mixing salt is a handy function, keeps things nice and neat and much less opportunity for spillages!

Used the Nano on my 50cm cube, when my tank upgrade arrives I'll be getting a bigger one for that.

Komfortabel und sicher

Had an ATU for a while. Having tried the new sensor, am finding it far more responsive. Top ups are more frequent, but of less volume. The old sensor needed frequent cleaning to maintain operation. Very happy with the purchase

Very well put together system.

Excellent product and fantastic seller

Easy to install/setup and works like a dream😁

This AT is really great, on top of that great service from Gordon. I ordered on a Friday and it was here by Saturday morning. Completely surpassed my expectations, easy to set up and nice and quiet. Bravo!

great piece of kit,changing water now is simple and easy
