Auto Top Off malfuctioned

[Stu]

John at brk knew exactly what i needed when i went from a maxi jet to my kalk reactor. He had everything in the shop that i need. Best would be to go in and tell him what you got. It was 2 fittings to reduce down to the kalk reactor with a check valve so i don't get a siphon back.

 

Thanks Bob. As important as it is to support our LFS's, I'd rather run down the street to the hardware store if the parts are readily available (BRK is a bit of a hike for me). Do you have any idea what the 2 fittings are? I already have the check valve installed on the reactor with 1/4" tubing. Just need to reduce the larger tubing coming off the maxi jet and reduce the flow.

I don't remember the sizes. Shoot john a pm

or take your tubing to a hardware store and see what they have.

How about the Tunze ATO? Anyone use this? Isn't it supposed to prevent things like this from happening since it uses sensors instead of float switches?

All of them are capable of failing ask me how I know.Or maybe ask my wife why hers socks are wet and she is screaming.

i have been using the JBJ for over a year now and its been so much easier not having to go home to check levels and top of my self. Anyways, this unit comes with two floats and is pretty much plug and play, one float fr the sump or are that you notice the evaporation and one float for the RO water bucket so that it stops pumping after a certain level.

I use 2 jbj's on my system. I did have 1 of the float switches stop working so i bought a new 1 and everything is good now.

A float switch with a backup switch isn't exactly rocket science. I already have an ATO that works great and a maxi jet. There is no reason to buy a peristaltic pump. Anyone with any constructive suggestions?

 

Rocko hit the nail on the head. Johnny has helped me twice with the necessary pieces to shrink the maxijet down to RO size tubing. You'll need two separate reducers, both of which BRK has stocked at all times.

The JBJ ATO will only run the pump for about 2 minutes. If it hasn't received a signal from the float switch by then, it shuts off anyhow. This can cause you to have to manually add some water once in a while (like when dipping a few gallons out for rinse water, or selling some large frags) - but it never overflows.

+1 on the JBJ ATO.

 

I bought my JBJ from BRK almost 3 years ago. It has work flawlessly and all I do is submerge the float in vinegar for several hours every 6 months clean it and put it back in the sump. Still using the original floats switches.

I have two - three years, and two years. No problems.

That makes me feel a lot better about the JBJ ATO sitting in my basement waiting for me to install it.

I had problems with the JBJ, too many mechanical things to get jammed up with calcium, snails etc. The tunze osmolator is the best unit, it uses an optical sensor and keeps the water at a constant level. More expensive but worth the extra dollars for quality german engineering.

THESE are a lot cheaper, and don't rely on any sensors that can fail (although I do agree that the optical sensor on the tunze is enormously better than float switches/sensors...those things are just a flood waiting to happen...which is why people usually have more than 1. Personally, I don't like the concept of solving the problem of unreliable parts by adding more of the exact same unreliable part...I've heard enough stories of floods from people who had that "back-up"....)

I actually just had my Tunze ato fail last weekend. It has only been in use for 9 months. The optical sensor failed so it thought the water level was ok and didnt add water. Luckly I was home that weekend and caught it in time. Apparantly they had a batch with bad capacitors. It sounds like they are take care of people even after the one year warrenty period. Hope they have a quick turn around, other wise thanksgiving is going to be rather scketchy.

Honestly the most reliable ato I have ever had is a gravity fed resevoir to a spectrapure stainless floatswitch. Even if it ever failed, it only can allow a couple of gallons. No failed sensors, floatswitches, or relays like I have had in other ato's
