What do you use as your ATO reservoir?

[saullman]

That is a unique but decorative way to store ATO water!

It's been working great for me for years now. I wouldn't change a thing.

I found what, to me, is the perfect ATO reservoir. US Plastics sells polypropylene tanks in a variety of sizes from 2 gallons up to 75 gallons and everything in between. I was looking for a reservoir to fit in the stand of my IM 200EXT using the space left over after using a 60 breeder as a sump and with all the different dimensions they offered I was able to find an 18 gallon container that perfectly fit the space. Cost was $103 plus $45 shipping for that size but it looks like price and shipping vary based on size.

The material is easy to drill and I added a bulkhead for RODI line so I can hook my kalk stirrer up to it and drilled a hole for a grommet for my ATO pump tube and wire. I also drilled a hole and added a QD fitting that allows me to click in a tube I use for refilling it rather than just trying to flop a tube into the original 4" lid hole and have it potentially fall out.

The fact that they have them in so many dimensions means there's probably one for nearly any application and the material is really impact resistant so there's no risk of cracking it, which is something I'd worried about with the fancy acrylic reservoirs. The cost was about the same as a 5-10 gallon acrylic reservoir but I get better use of the space in my stand and a lot more capacity.

The attached photos show the container test fitted under my stand and show the additions I made to the top to make it work well for me as a reservoir. I drilled the hole for the QD fill point before I had the fittings and wish I'd drilled it further from the edge but turning it sideways as it is shown works perfectly.

I use a brute trashcan, its in my basement. A dosing pump pulls from there, it works great and was pretty cheap!

Sure it's a nice container for rodi, but how much did it cost?

This square container fits my space...haven't bought it yet.

I actually bought the 18 gallon version that's slightly different dimensions (because those dimensions fit my space really nicely). I've only had it about 6 weeks but it works really well. The material is super thick and durable; I'm sure you could throw it off the roof and it would just laugh. I drilled some holes in the top and added things like an RODI bulkhead so I could fit line for my kalk stirrer, a hole to put a grommet in for a place to feed the ATO pump tube and wire, and I added a 90 degree PVC fitting to the top with a QD so I could easily click in my fill tube for refilling rather than using the lid the container came with (especially since I don't have a ton of space above the tank in my stand so trying remove the 4" lid and drop the fill hose in there would be a harder reach.


Having bought the typical fancy acrylic 5-10 gallon reservoirs in the past for other tanks, I really like how these are in a variety of dimensions so you can optimize it's fit to your space but the build quality was a pleasant surprise. The size I bought is 15lbs and it's thick enough that I think you could tap threads into it if you wanted. They're also really well priced for as ideal as they are.

I paid $158 for the 18 gallon size. It was $103 for the container, $12 for tax, and $45 for shipping.

and it looks like for their smallest, a 2 gallon container, it's like $60 for the part and the shipping estimate is $12 so it does look like shipping is adjusted based on size/weight and other containers might have higher or lower shipping costs.

I was contemplating doing something similar...you didn't have any issues with head pressure? Which pump are you using?

No problem with head pressure, using a Neptune ATK pump though ro line. Have a solenoid and float at tank end for redundancy.

This is what I use

 

[Bruttall]

300g DT 125g Sump 75g salt reservoir for daily water change, 50g RO/DI reservoir with ATO inside it (White plastic cube under DT).
I circulate roughly 360 gallons in my tank and sump. Home Depot bucket is my Skim Locker. I have a Sensor in that bucket hooked to my Apex that will shut off my skimmer if locker gets full, best thing I ever added was that switch.

The Fish Room!!

I've been using this great looking reservoir for a few months now. Ain't she a Buty!
Got a handle on it so I can take it out and refill it...

 

[jimeah]

Just a standard 25 litre potable water tub so no leaching and the DD auto top up pump is small enough to go through the hole, drilled into the lid to reduce evaporation.

It was an ugly solution with my other tank due to not having enough room, but I “hid” it beneath a table.

If it fits, works and is hidden, it doesn’t need to look or cost designer!

I've been using a brute can in my garage. I think it's the 30ish gallon one? I just got a new tank that is much bigger, so I'm gonna upgrade it to a 100 gallon rubbermaid stock tank with a cover. I have my rodi unit in my garage. I flush the lines a while, make sure it's reading 0 TDS, and fill up my RODI and saltwater bins. Have the cables running outside my house and behind my fishtank for both my water change and ATO. Since I was setting up the AWC I figured I may as well just run the ATO that way as well and save space inside.

 

[ros3to]

I use this. Lids come with a hole in center and a rubber plug that allows me to run the water line and the power cord through
