I'm fighting a GHA outbreak pretty bad. My TDS is zero but do you think it could be source water? I run a 5 stage but maybe need to add more

1st question. No all wrong. I have 480 before membrane.i have 14 to 17 when flushing. When I stop flow of water I get a rise of up to 200 for some reason. Flush and everything is ok. Back down to 14 to 17 ppm .
I run a duel membrane 7 stage. 1 micron filters.
Yes when I say resin I refer to di mixed bed unless specifically saying anion or cation.

Thank you. Sounds like you have it all worked out.

To answer your initial question, I see a higher use rate of the anion specific resin over the cation. Anion is used up at a rate of 2-to-1 over the cation. I can only imagine this has something to do with the specifics of the Memphis water table. I do not seem to burn through it at the rate you listed and typically get 4 months out of the anion before having to change it.

No need to run additional stages if you are getting 0 TDS at the end of the process unless you want more control of the di resin use.

I would suggest looking for a different source of phosphates for the GHA. Have you changed anything recently that would impact this - changed lighting, more fish/food, change of food, added any new rock to the system, etc? When was the last time you refreshed your clean up crew? Is the tank getting any direct sunlight (where mine is I get some sun for about an hour during the summer months but not in winter)?

Yep for me it was zero coming out but needed that final polish and assurance of at least second di. I was getting diatoms

My tank gets some sunlight no issue. Pickup maintained. Flow.

I’ve noticed my resin doesn’t last long either. TDS coming in ranges from 360-380. I run a 5 stage system but recently went with 2 resin cartridges as I was struggling to get to O TDS

Adding a duel di from brs fixed this for me so I'm running the 3 blocks duel membrane 75 gal and 3 di stages.

So you run the cation anion di setup? This is due to this An anion is an ion with a negative charge. Common anions include Cl-1, SO4-2, and OH-1 .

Anyone else blasting through di carts. This was one 50 gallon tds 14 going in 489 at tap.

Switching to cation anion next or do we thing something is wrong

you might consider changing out your RO filters that is only 97%, if you could get it down to 99% that would help a lot. but at 14 TDS you are probably going to go through it pretty fast. it will help to use separate cation, anion, and mixed. I change out my anion about 3X to one cation. most people use a lot more anion, so the cation di in the mixed often goes to waste.

That's a fresh change friend lol life sux

do you use duel RO filters, like the BRS water saver kit?

 

[Thuan]

do you use duel RO filters, like the BRS water saver kit?

I use dual membranes and booster pump. Currently making water. 34 out of tap

No each is fed separate thanks to battlecorals guidence.

That may be the key a booster pump but to much work. I use the premate booster pump

 

[Ado]

I'm using the 5 stage brs one at around 65 psi. You guys think I should add a booster pump? I'm thinking about adding another stage so I can have 2 resin, one of each

 

[Joe462]

yeah, but you are in a very different situation than he is. dual membranes is fine if your TDS is low. but when they are higher the dual membrane set up can be a problem.

each what?

Aldo cation anion doesn't work that way I don't think if that's what your doing. Still need mixed at end

 

[robanister]

each what?

Membrane. Not in water saver configuration.

don't need mixed at the end but its a good fail safe. should be 0 after anion.

Your water pressure at 65 is good.

If you add a 2nd resin chamber run them both with mixed bed. You will see the first burn up faster than the second. When the the first one goes out you swap it with the second chamber's resin and put the new resin in the second chamber. This way you get max use out of the resin.
