What's your ATO system?

[Diazreeflife]

I'm at the point where I am setting up a auto top off system. Can I hear what systems everyone is using DIY or store bought?

Thank you

Avast pressure switch with Avast peristolic pump fed from 5 gal "Sparkletts" water bottle. Pump is kinda loud when it runs but I use kalkwasser for ato so I didn't want traditionsl submersible pump. Didn't want to replace pumps every year.

+1 for avast. I use the avast ATO, a small powerhead and a 5 gallon bucket

tunze osmolator. uses an optical switch which is much more reliable than a float switch. also has a float switch to shut it off it water level gets too high. the little pump it comes with fits in a standard 5 gallon jug and works great. well worth the investment.

+1 I have this one too.

BUT.... It can fail however and mine has. If micro-bubbles accumulate on the electric eye it will think it is out of water and call for a fill. The manual float can (and did for me) get stuck. Make sure your sump can handle the ATO volume just in case. And jiggle the mechanical float once in awhile. It also has a stupid design flaw where it outputs about 12oz of water every time the power is cycled. So if you turn it off for water changes, when you turn it back on, it will add water to the tank. I catch it in a cup and dump it.

Spectrapure UPLC II, similar to the Tunze but more reliable since it uses an air/electronic switch and has multiple safety backups.

I use an ATO from JBJ. easy setup and reliable.

 

[robbrouse]

JBJ here as well.. Over to year no issues.

I really like my JBJ ATO its simple cheap and works effectively.

I use a JBJ ATO on my 240 and a Tsunami AT-1 auto top-off system on my 50.

I have been trying to decide on a ATO, and have been leaning towards the Avast. The Tsunami AT-1 seems to be similar but from what I have been able to find has a 1" threshold where the Avast has a 1/4" threshold.
Has anyone had a bad experience with the Avast unit? Failure to shut off, or complete failure requiring replacement? I would definitely want to use the backup float valve on the incoming water.

I use avast with Elite Aquatics 10 Gallon

Gravity feed from 10 gal RO/DI reservoir to old-school Kent mechanical float valve. Hasn't failed me in 15 years. Works even in power failures

Same here simple with a small pump been using this one for years

Gravity fed? If my RO water is above my sump next to my tank should I just go with gravity fed?

 

[NanaReefer]

JBJ ATO & a 5g bucket. Running for almost a year never an issuse

 

[Small triggers]

Avast ato, aqua lifter pump, 5g HD bucket,lol love the ato...moved it from my 50g to my new 150g I just got up and running...had it for over a year and a half no problems..

litermeter III on an auto topoff switch

Avast ATO with a Tom aquatics aqua lifter pump. Cheap, simple and flawless so far.
