Really great product, makes your life so much easier. Gordon is very responsive and helpful.

Absolute game changer for water change, your floor will thank you!

Purchased this as an updated redundancy item for my existing pro1kit with the Red Sea sensor. This old kit was purchased in early March 2017, still going strong and has never missed a beat apart from having to buy a replacement pump last year!
The new pro4 looks extremely well made and has great features such as warning lights and alarms. I love the fact that the pump and hose have a good length of cable and pipe. This enables me to top up water from a separate 60Ltr barrel, instead of the tanks built in one. Especially useful when I am away from home. I am looking forward to using the Pro4 properly. It might be some time though because my original is still going strong!
Many thanks Gordon, loving Reefloat products.

Awesome, Me and my Aquarium loves it!

Thank you!

Fast postage came in two days, was initially missing a piece but after an email to Gordon (he replied in two minutes... LITERALLY. The part came a day later first class.

Never been a fan of mixing my own salt, So I bought two drums filled the machine up and switched it on.

Two hours later it was done spot on no mess wheeled it over to the sink and flipped the switch to empty. (Bought a little dolly trolly from toolstation) spot on and couldn't be easier.

I have been dosing for the last 3 months and although everything is stable I could see a different in my corals the day after.

Great product Gordon keep up the good work.

Well… 1st water change with this device was a dream. I will have to adjust my new routine: mixing downstairs and some stairs up or mixing in living room… where to put the tubes when transporting… but first try was great!
So far: work’s great 👍

Having recently increased my reef volume from 600 to over 1000 litres it was time to replace my trusty 53 litre AWC that I have had for 6 or more years without issue. The new AWC106B unit is of equally good quality with a few enhancements. I love the new switch to empty the unit. I have put it on a trolley the same size as the unit so its a case of fill, mix, wheel to the tank and go. Very clean and simple. Thanks Gordon for yet another great purchase!

I have always rated Gordons products, I have used his stuff since he first started, from AWC’s to ATU’s, he’s also helped me out numerous times at his own expense when I’ve needed quick fixes for other things or advise.

This new ATU is great, got it installed in my sump, an although it’s tight (my sump) managed to calibrate the sensor just fine. It’s very well built an is made to last. Always loved reef floats stuff due to the built in alarm system, can’t fault that at all it’s a great feature. Thanks for making another great product Gordon 👍

Good timing really as I've just, well 2 hours ago done the upgrade, took all of 5 minutes, am I pleased, hell yes, after fitment I did a trial test with a jug of ro, the accuracy is amazing, with a 1 litre jug half full of ro, removing just 3ml with a syringe would trigger the pump, adding the 3ml back to the jug stopped the pump, am I pleased..........very

This was really easy to install as a replacement for the optical sensor. Very happy with the performance as it seems to give small and frequent top ups which can only help stability.

Only issue I had was recalibration of the sensor due to where it is installed in a reefer V3 sump.

If you are thinking if upgrading my advice would be to grab one when they come in stock and do i

t.

Ordered this pump after excellent advice from Gordon. It arrived quickly and worked perfectly.

I have had many auto top up systems on my tank. This is the only one that consistently work’s flawlessly.I cannot recommend this enough. Absolutely brilliant bit of kit. This is the 2nd one I have bought and the original did not come with the magnet to hold it on the sump. I spoke to reefloat and he sent me one out free of charge. Great service.

Since using the reefloat AWC my water change is so much easier, no more multiple buckets as this unit does it all, mixes the salt, removes dirty tank water whilst replacing new water at the same time.
I did use a heater to warm the water a little but if I hadn’t stored my water in the garage I probably wouldn’t have bothered with the heater
Absolutely thoroughly recommend this product!

Many thanks to Gordon for all his help in this matter as I cannot commend him enough

Basically my ATU Pro2 (One of the first ones ever produced with the black IR sensor) finally gave up the ghost after more than 7 years faithful service in a humid environment.

Took around 5 minutes to swap everything over, including soldering a new female connector to the pump feed wires.

I had already desinged and printed off an adapter in PETG to take the newer IR Sensor 2 which Gordon also supplied free of charge. I didn't really fancy making the hole larger in the original ATU Pro2 mount as acryllic can be quite brittle when it comes to being drilled so it was easier to make the adaptor.

I may also upgrade it to the newer ATU Pro4 once the newer sensors are back in stock.

Once again a BIG thank you to Gordon for all his help as not many companies go the extra distance that he does!
