Plumbing BIG water containers

[Cwentz758]

So I got these water containers for a steal awhile back. With the basement being completed it’s time to plumb them up and prep them for the upgrade later this year.

the tall one is a 100g container with a bulkhead at the to and at the bottom with a union.

the second is a 35g container with a bulkhead on one end with a gate valve to a barb fitting. On the other end it has a port for RODI water to go in with a float inside the tank. Along with a bulkhead with a gate valve with two RO line ports.

For some reason I can’t quite wrap my head around on what needs to connect where. I’m planning on using a small external pump as I don’t/won’t have a lot of head height just need to pump around these containers and eventually a sump built above the 35g. I’d like to keep a closed loop to keep the 100g moving as it will be salt water and pump fresh water into it by closing the bottom valve opening the 35g one and pump up.

I’m not sure how the ATO connections work

looking for suggestions. Also plan on using mostly silicon tubing just for ease of changing things.

well good job on the 'steal'
I think if you work out the process that these tanks are used in, you might be better able to visualize what the plumbing will need to be.
i cant tell from the picture. What does the top of the tall tank look like?
where will you mix the salt into the water?
how will water changes be accomplished?
what heating needs will there be?
how big is the system that this will support?
Where is that system? Where will the sump be compared to these tanks and the system?
Will the removal of used water be pumped or gravity siphoned?
the drawing looks adequate for moving the water but i would use internal agitation to initially mix the salt.
the type of pump you use will determine where it should be located, some pumps do better pushing water, some are better at pulling.
i would consider leaks and overfills and how they would be managed.
good luck!

When I upgrade the sump will sit above the 35g which is about 3 feet from the tall container. The DT will be directly above the sump in the living room with approx 10ft of head height. However that part will be hand later on when I upgrade.

water changes will be pumped out of the sump into a drain and then the external pump from the containers will pump fresh salt water into the sump from down here. Here’s some additional pictures. I have some spare tunze powerheads I could toss in to internally mix. Heating wise the basement is always around tank temperature so I’m not to worried with the heating part.
