Considering ATO

[whatcaneyedo]

I used a simple float valve and bucket for a few years. It worked well except then I wanted to start including kalkwasser in my ATO which would cause the valve to plug up all of the time. I would also manually fill the bucket which meant packing about 15 gal of water across the basement each week. To deal with the kalkwasser issue I bought a used Tunze ATO for $50. It lasted for about 5 years until recently the photo eye started to act up. Sometimes it wouldn't start and sometimes it wouldn't stop. Rather than replace it with a new system I recently just added two float switches and a maxi jet to my Apex and programmed it to do the ATO. So far so good so I'll just leave it alone for now.

To cut back on my weekly bucket brigading and for a few other reasons I've got an RO/DI on a solenoid controlled by the Apex to top off a fresh water can three times a week. I recall reading somewhere that its not good for the membrane to run short bursts of water through it so this allows me to run it non stop for a couple of hours at a time. It also means that if something sticks on I won't flood the aquarium with an excessive amount of freshwater.
