I’d spend all week dreading the big water change. Now it’s a breeze. I don’t pretend to know it’s secrets but this magic box has saved me from days of recovering ❤️‍🩹

First class product does exactly what it says on the tin..big time saver .

This ATO is essential, I have full confidence now the system is being topped up whenever it is needed. The failsafes provide me with comfort in knowing the device will handle things effectively and I will be notified to resolve any issue without a flood. The device knows when my hands are in the sump and won't trigger, another great feature. Overall I highly recommend to anyone.

The awc53 from Reefloat is just an absolute god send it makes life a lot easier for water change’s and the company itself comes with amazing customer service

Loving this new AWC88b It's easy to work with, clean and consistent. I love the fact that the water change takes 4 hours because it reduces parameter shock to my system.

I've always toyed over getting one of these so glad I have an absolute brilliant bit of kit no fuss straight forward ti use and no hassle at all sit back and let it do its thing all corals and fish have a nice grin and extremely happy 😀

I gave up tropical fish keeping some years ago, being in my early 70s the water changes were getting too much for me. Having discovered these water change units when surfing the net aroused my interest in fish keeping, only this time what I always wanted was to keep marine tropicals, I went ahead and purchased a marine tank, Red Sea was my choice plus accessories, I then purchased this AWC 53 and am over the moon with this machine, being an absolute must for all marine fish keepers. I then reviewed several ATU units and found that this company sold what I thought was, by far the best option and like the AWC the ATU unit is by far a winner.

Excellent, time saving, efficient, automatic stable change process which does not alter any water chemical parameters too quickly. Highly recommended.
