ATO Resevoir Suggestions

[xWascallyWabbit]

Good evening fellow fish nerds.
I am currently looking into adding/upgrading my current system with a Kalk stirrer.
My question is:
What type of ATO containers to you all recommend. I'm looking for one that could be 8 to 10 gal.
I see some nice slick one on BRS but main are they expensive for a container to just hold water. What economical options are out there.
P.S. My plan is to is this container to feed the Kalk stirrer so that is it separated from my existing ATO res in the sump. Thus extending the amount of time each will last.

Interesting idea. I do have an old 10 gal from petco. Already has a lid. Maybe I will DIY a nice white box with a lid and a cut out for tubing. So that it looks nice next to the tank.

I have an old 14g Biocube that I had laying around and turned into an ATO reservoir for my waterbox 20. Only have to fill it up maybe every 6 weeks? Pretty nice! I’m thinking about adding kalk to it as well with a wave pump in there to keep it mixed up.
