Red Sea 3-in-1 ReefATO+: Watch this 8 week review before you buy 

Nice overview of the ATO. Certainly one to consider for the future.

Cheers Paul good tip on the Syphon breaker I have bought one but yet to set up 👍

Awesome video ❤❤

Does this ATO support a schedule to where you can turn off or disable the ATO to perform an automatic water change? I ask because I seen no mention of it in the manual for this and my Apex does an AWC for me everyday.

It's a good product. Compared to the Tunze 3155, the pump is much quieter. It also "primes" itself - so no need to shake the pump up and down after replacing the reservoir e.g. the next 25L container of RO/DI, to get the Tunze to be primed. The flow monitoring is accurate for me, because I calibrated it after setting it up. Apart from being an ATO, it allows the temperature to be monitored - with the D&D Controller and D&D Heater it shows that the regulation is very stable - nice to know. FWIW, the siphon break isn't required if the height of the RO/DI container highest level is below the height of the output in the Sump. I found that using the siphon break prevented any water being pumped to the Sump or (adjusting the height of the RO/DI container) for the delivery not to be accurate. A 25L container (for me) is below the height of my Sump top - so no need for the siphon break. The siphon break "fizzed/leaked" when used either way round, so couldn't be relied upon. I might need to get it exchanged. Measuring the delivered water sometimes shows big swings in daily use and it really drives home just how much evaporation there is especially in a bigger uncovered DT. I also use the "Check" water level feature after a water change. Added 25L of water, siphoned off 25L of water. Check the Return Chamber level. If the added/removed volumes don't match, then this also changes the salinity. The "check" water level feature lets you get this balance (in theory) just right e.g. take out/restore siphoned water before switching the auto top up back on. Turn Skimmer back on but leaving the ATO auto top off off, I wait for the DT Weir to stabilise and then add/remove water from the Sump until the Return Chamber is registering in the "normal" range of the ATO. Can now resume Auto top up. But for me, there is a problem because the "Check" water level can show that the level is below the required level but, repeating the test, that it is above the required level. That can't be right! It is almost like tossing a coin (semi-random). At best, it should indicate one of the four levels and then the next/previous one" because levels don't change that quickly in the Return Chamber. So the + in the name is justified by the extras and compared to other "premium" ATOs it doesn't cost any more. Simon

Love Red Sea products, but for some reason I'm less excited about this one. How does the price compare? Enjoyed the video and a very balanced view. Big thumbs up from me 🙂👍

I'm looking to get the same tank. With this ATO, where does the water level sensor go? The sump is built into the back of tank

What type of ATO container is under cabinet and how many liters or gallons.
