Review of product

Verry good bit of equipment
Does the job verry well

My personal negatives
Controller didn’t last long before the pin power pin corroded as being used with salt water

Spare part was expensive

For the price of this Product I really feel it should come with the tap drain from factory not an optional extra Or failing being fitted should at-least be be supplied to give customer the option

Hoses in my opinion of my application should come at-least 1/2 foot longer

Other than the above great product
Really pleased with it

Easy replacement

My old unit started to get unresponsive so like what you have to do to a car is service your equipment I done this in about 5 minutes now running as it should
The perfect solution

Hi I bought a auto top up for my tank, I ordered the wrong one as the sensor can only work on 9mm glass and mine is 10mm, I contacted Gordon who was very helpful, and replace it with a sensor that goes into the water, very quick and helpful highly recommend them, I'm also using the automatic water changer 53 litre which I am also very happy with

All working well

I appreciate the advice from Gordon on how to cure a problem with the awc. The new updated controller was very easy to fit with all the necessary components supplied.

I needed a new controller, as mine had broken at the power connection.
Received the controller very quickly in the post, had a quick look on reefloat's web site, just to see how to change it, as it was different to my old controller, found the info, and changed it as quick as a flash. Now I'm back up and running with my ACW28B.
