Salt Water Mixing Stations Let's See Them

2 65 gallon tanks with a blueline 40xd pump. I have a couple questions?

The tanks are vented is this okay or will my water get contaminated?

Do i need to keep the salt water circulating 24/7. Especially if the tanks are vented

any thoughts suggestions or opinions would be great!

Mine are vented and outside but the saltwater tank is always circulating. I'm paranoid and think that the water will go stagnant if it isn't kept aerated, even though it shoudn't have any life in it.

Looking at your stand, I used what looks to be the exact same for my sump/Fuge. The particle board got wet & started to crumble - would have given out but I caught it. I actually had to jack & brave the shelf while I built a brace.

I made a 2x4 frame for the tank to sit on that extends just past the rail to keep weight off the board & been ok since.

Heads up from my experience!
 
Ok. I gotta ask... You all have some very beautiful, and well engineered stations. I have been studying this thread and trying to design one myself.

Not criticizing anyone's build by any means, but, I do have one question, though. I was in the process of ordering two tanks when it hit me. Why does everyone have 2 large tanks of the same size? One to hold RO/DI and one to do the actual mixing. If the water is only transfered from the RO/DI tank to the mixing tank, can't the RO/DI water be transferred directly from the RO/DI filtration system directly to the mixing tank? I understand the need for having RO/DI water for top off purposes and such, but, why would so much be needed?

Again, please excuse my in-experience. Not poking holes in anyone's plans. Its just easier for me to design something if I understant the reason for it. May be an opportunity to save money and space by having a much smaller RO/DI tank and running a splitter from the RO/DI filtration system to fill whatever tank I'm needing filled. Mabye, I'll learn something, and end up having two twin tanks as well.

Thanks all!!!

You answered your own question: just to have RODI on hand. I continually need topoff water, my system evaps 2-3 gallons/day. My RODI station feeds directly to my ATO reservoir at the turn of a valve, so it's basically for simplicity. I don't have to make water but once a week or so. Also in case of emergencies, you have RODI on hand to make new salt.
 
Goodness. Your system actually evaporates 2-3 gallons per day? Mind if I ask how large your system is? I'm setting up a 120 gallon system w a 55 gallon sump. I know I'll have to have some RO/DI on reserve, but do you all think I'll be alright w a 55 gallon mixing tank & a 25 gallon RO/DI reserve tank?

Oh yeah. I also have a 55 gallon FOWLR office tank. That's 40 gallons for the 120 and 15 gallons for the office tank for water changes.
 
Maybe it's more like 1-2 gallons, I just know I fill it up every other day or so.

The system is a 105 rimless with a 40 sump. It has LEDs, so it's not heat, but I think evap on rimless is typically higher as well.
 
Goodness. I had no idea they could evaporate so quickly. I have my tank 85% covered for now. That may change once I get the canopy built.

Thanks for the info!!!
 
These kind of theards just make me spend money and drive my wife nuts but sadly i have a lows bucket with a big spoon for now but only a 10 gallon tank dont need nothing crazy yet
 
?s

?s

so here is what i have mocked up.. 3 40 gallon tanks, pretty self explanatory.

My ? however is does this look alright to those who have done this already? or should i add a gate valve behind the mixing and ro tank on the intake line? didnt know if i would get unwanted air in the line when just intaking ro water or freshly mixed saltwater.

There's no need to have a separate container for mixing because once you have salt water on hold it will constantly needs to be mixing anyways.


Can someone confirm this?




Sent from my private Jet.
 
first of all that is not true.
second i want to be able to mix up a new batch prior to my current being used completely.
i run a continuous water change of 2 gallons per day, i dont want to have to take my water exchange off line in order to make a new batch.
 
i dont have the footprint for 55 gallon barrels, i actually just gave two of them away.

i posted earlier i want to be able to mix a new batch up separate from my current NSW container.

After 24 hours of thoroughly mixing a new batch of SW it will be sent to the NSW res, where it will used in my continuous water change.

the extra mixing container also gives me the option of making any size batch up to 40 gal with little effort, send ro, dump salt, mix and send to res.

this also aids in cleansing of the containers, as i will not be mixing but in one container and the precipitates will only be left in the mixing container. which i can clean and still have my water change in line while doing so.

ill just add the ball valves to be safe, and post with results when finished.

Cheers
 
I would use at least 2 pumps and more plumbing to be able to control the mixing functionality. You should try to think of every possible way you will want to use this configuration and make sure your pumbing and pipe structure supports it.
 
Where did you find the plastic red handles? I have gone to both lowes and Home Depot looking for those and can't find anything but those stiff valves?
 
Really nice setups, absolutely stealing someones idea for my own build. I do have a question though. How are you guys balancing the water you're adding with the water you're taking out?

Are you pumping water out where it is measured to equal the amount you're putting in?

Example: I want to add 25 gallons. before I can put 25 gallons in I need to take 25 gallons out. How are you metering this?
 
I have one pump in the new SW barrel, and a matching pump in the tank overflow. both have secondary valves to control the flow rates and I match them so the water removed from the overflow (going to the drain instead of the sump) and the water going into the sump are equal. water changes take 15 minutes and the only effort is operating a couple of valves and switches.
