ATO and Kalk setup discussion.

I have my 65 gallon aquarium pretty dialed in, but now I'm looking at ways to make the daily tasks more automated.

ATO seems to be a natural progression since I dose kalk daily. I'm pretty set on investing on the Tunze ATO.

Can you describe your ATO setups and how you keep the Kalk "fresh." Any recommendations?

I will be taking pictures shortly of the space for the container to give you a better idea and maybe help in the recommendation.

Thanks everyone!

I'm not sure if you have a controller or not, but I just use a small float in my sump wired to the controller to trigger a peristaltic pump that delivers the lime water from a still reservoir, the pick up tube is about 3-4" from the bottom of the reservoir.

There is no real need to attempt to keep it "fresh", attempting to mix it will have the opposite effect.

I fill up my ato reservoir, dump in the kalk powder, give it a half hearted swirl with an acrylic stick, then forget about for about a week when its time to refill the reservoir.

I agree with the above post in that it is best kept fresh by closing it up (like in a trash can) and not messing with it. No stirring, etc. Once mixed it is fine for weeks. :)

I have a RK2 controller.

Great info, makes perfect sense.

Will do thanks again.

Randy thanks for the links, I always enjoy reading your articles, always informative.

The tunze wont work, you will need a topoff that can handle limewater.

Really? I have heard of people using the Tunze unit with Kalk. That doesn't disprove your knowledge, but I'm a little surprised.

Can anybody else corroborate this information?

The guy who owns BulkReefSupply ran kalk in his tunze topoff for many years ( I was his tank sitter for vacations ) .

The pump does wear out over time ( about 1.5-2 years ) because of it but it's like a $26 replacement part.

Here is the vid from BRS specifically making reference to the Tunze ATO.

The solution that I have succesfully used for years is to combine the Tunze osmolator and a kalk reactor. I use the tunze pump in fresh water resevoir and then run the output line through a PM 620 kalk reactor before it goes into the tank (you will need to use a check valve to prevent back siphoning.) This works very well IMPE.
