Chloramine monster

The .5 sediment is from spectrapure. They sell some good stuff!

could be pressure is too high going into the membrane or somehow flushing contaminants back into the feed. Check specifications, but i think u want about 60-75 psi going into the membranes. also. u will lose 10psi after the first membrane so 60psi is a good min for your setup.

the membranes should last 2-5 years.

Getting 0 TDs on output. And around 13 TDs before Di.

Wow your rejection rate is poor..

I have the following:

Sediment -> Booster Pump -> Chloromine Monster -> Univeral Carbon1 -> Univeral Carbon2 -> Universal Carbon3 -> RO1 -> RO2 -> Di1 -> Di2

My tap is 375 and right before DI1 is 8-9TDS.

How many gallons before your DI1 exhausts?

I haven't checked I'm also maybe having my booster pump too high psi. Going to lower it to 60 psi from 80 recommended by aqua FX.

It is simply the ratio. Those membranes want a 4:1 ratio, even when in series. Cramming water through them reduces the life, the rejection rate, and the water output quality. Scuzy is running them at 1:1 which is not an ideal scenario.

Switching the ratio to 4:1 would probably increase the DI life by 3x if the membranes aren't damaged. Switching to Spectrapure 99% membranes at a 4:1 ratio would probably increase DI life by 6x.

Well here is something weird.

I tested my water for total chlorine in my ro container and my salt mix container. Ro and salt mix is 0.00 yet my tank went from 0.12ppm to 0.40ppm or total chlorine and I can't figure out where it's coming from. My top off is also at 0.00ppm. going to do a few major water change to lower this as it's starting to affect the corals.

Only thing I can think of is the carbon is exhausted and it's leaving back into the system. Out with the carbon put in fresh carbon. Let's see how this works out.

Can the hanna accurately test in sw?

I run a closed loop in my rodi storage bin with a mixed bed di cart in the loop. Makes me feel warm and fuzzy.

I use an eheim so there are no metal components in the tank.

My rodi is setup like this

1micron sediment -> brs chloramine monster -> chloramine 10bb puratec -> chloramine 10bb puratec -> booster pump -> 100gpd membrane - > 100gpd membrane in series -> dionize cart.

I'm getting 300 TDs from tap and 20tds before Di .

I notice that I'm still seeing very small trace of 0.06 total chlorine on my product water. Would adding another chloramine monster in series be a waste of time?

I was thinking of swapping out the 10" sediment fter with a 20" sediment filter and adding on one more brs chloramine monster. Anyone think those is an overkill?

Thanks

I have the AWI Typhoon 5 stage with the stock filters (sediment, 2x carbon, RO, DI) and I end up with about 5 TDS coming out of my RO before DI. The input water is around 250.

To answer your question, yes I think it's overkill. I think what you already have is overkill lol.

Got one of these bad boy and a big blue housing real cheap on eBay let's see how long the Di lasts in this bad boy.
