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.

Item arrived very quickly in good condition. Straight forward to fit, only problem my poor eyesight and clumsy fingers. New style infra red sensor works great.

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

The only regret I have is I wish I have bought one sooner. This has made an extremely tedious chore enjoyable. It has improved how I take care of my tank. I have replaced multiple buckets as my make-shift mixing station with this one sleek device. My wife is happy that we got back the space all the buckets and bins were taking up in our laundry room.

That's not even the best part, the best part is this kit is a set-it-and-forget-it product - which frees my weekend up to do other things around the house while the water changes.

Overall really happy with my purchase 10/10 will recommend it to my other reefing friends.

Just want to say - absolutely amazing time saver hassle free product . So easy in use . Recommending this to everyone

Very happy with this, makes water changes so easy.

Quite simply these bits of kit do exactly what they describe with the minimum of fuss. A brilliant device that reduces an essential maintenance task to something much easier - meaning in my lazy case I actually do it properly! Once you buy one you start to question why you didn't get one sooner!

I have a 5 month old and a 3 year which pretty much made water changes impossible. My 120 gallon tank got put on hold basically. Now it’s coming back thanks to the ease of this tool!

Absolute god send

I’m Pretty new to this hobby and after Searching the web for ideas on water change this site pop up
Didn’t really want to buy loads off drums and buckets and thought there must be a easier option
And there was
Sent a email for recommendation and was advised on size off unit for my tank
Once received item looks great and well made can’t wait to try out looks very simple to use with no messing about
Great item would defo recommend

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 .
