I have now had the Red Sea 3 in 1 Reef ATO+ for 8 weeks so what better time to review this product. Is it a must have, a nice to have and is it unique in the ATO market.

What we know from the box is that it is not only an ATO but also monitors tank temperature and also has a leak detector too and all managed via the red sea app.

Take a look and see what you think
