Coral Shop and Didosy have collaborated on this little gem of a dosing unit. I have been using one for about 3 months and still get excited by it. Firstly this just oozes quality. with a polished stainless face and stunning blue lcd display this looks like a piece of art, just a pity mine is hidden away next to the sump.

4 channels with clearly marked in and out ports make the set up easy. It took me a few minutes to get the hang of navigating the programs, but once you have the date and time set it doesn’t take long to get the dosing levels set.

The Tower profi‘s led display is continuously passing through individual readings of each channel giving you information on each channels dose volume, cycles per day and container level. The last of which I love, no more shaking bottles, the led display shows how much is left in the dosing container and will sound an alarm on low levels.

Then there is the optional extras. There is a TOWER Profi acrylic dock - standalone or for wall mounting. Which perfectly hides inlet and outlet tubing and a 4 channel integrated acrylic hang-on outlet hose holder for glass thickness up to the 20 mm which organises all of the outlet hoses perfectly on the sump or aquarium. The plastic inlet hoses to insert into the containers of products to be dosed are stiff so can be cut to length to fit perfectly for drawing the maximum from the container. Everything about this has been thought through to the max.

I have been using 3 different dosing systems and this one has it all. My only negative on the Tower is that there is no extension module for extra channels. If you want to dose more than 4 products you will need a second unit.
