Top off system question

[Michael John]

I picked up a Tunze osmolator 3 a few days ago and am figuring out adding it to my top off system. Thinking about the higher co2 in my tap water brought this to mind.

Is this advisable? Water from ro system goes to water storage container --45 gal brute grey, continuously running a few air stones in the storage container to degas, then push the ro through my tripple DI Anion, Cation, mixed bed, by using the osmolator 3 pump to push the ro water through the DI on its way to the tank?

Im currently running water from ro to di, then storing DI and topping off from there.

The pump should be strong enough. Let us know how it works out

Going to take the water system apart over the weekend. See if I can come up eith any additional ideas.

If anyone has any input, Im open to suggestions.

I'm not sure if this is a mistake or not but your DI resin should be Cation, Anion, mixed bed. You have them listed differently.

Do you run "outdoor" air to the airstones? Otherwise I got nothing!

Was a mistake in memory for order of operation. It is set up as big whole home Cation --water softener, D I filter Cation, DI Anion, DI Mixed bed. Im one of the few who truly appreciate being corrected when I am wrong or inaccurate. Thqnk you for doing so.

I did not consider outdooe air up to you mentioning it. I have a few ways I can make that happen if it is the preferred method

Thinking further on contaminents, the house is of a rectangle, no seporation, kitchen / dining room design, approx 26 x 15 combined, one on each side, reef is in the middle of the dining room half, against the opposite long wall from my stove. Stove is middle of the kitchen, along the other long side wall. Diagnolly about 15ft away from each other.

Was planning on continuoiuly running a small amount of carbon to pull out contaminants.

That was a part of my interest in running the top off water through the DI immrriately before entering the tank.

Also, if anyone has any suggestins for keywrods to search, Im open to suggestioms. I inintally thought circulation, howrver.. reef forum.

Is all this actually necessary? What are you trying to achieve exactly?

It seems that the water supply inside the house has elevated CO2 levels that the OP is treating with a air stripping stage after their tap water has passed through a reverse osmosis system the ro water goes into a brute bucket where airstones are used to strip the water of CO2 before the water is pumped through 3 stages of resins to remove the few remaining ions from the water.

Water supplies (often well water) that naturally contain high CO2 are routinely treated with air stripping to remove CO2 to reduce the amount of DI resins that are consumed by the filtration process. High CO2 content will cause the filtration process to “burn through” resin to achieve zero tds for top off or for making salt water with.

The excess CO2 in the water supply will possibly elevate the baseline CO2 levels in the occupied areas of the home. Bringing in outdoor air should improve CO2 stripping in the water filter the same way that it does when using outdoor air in a protein skimmer.

The impact can be improved tank pH baselines and reduced expenditure for consumable DI resins.

Thank you for providing the lengthly explanation to those unaware of this issue. I deal with a combination of that and rediculously hard water here in the Midwestern US and burn through DI resin very fast. While I cant dont have the ability to do much about the water before it hits the ro, I can do something afterwards, pre DI, and I want to do what I can to extend resin life.
