Major RO issues

[N2theUnknown]

I just bought 30 gallons of distilled water tank is probably 45 gallons how big of a water change should I do? I do have some corals in the (they aren't doing well anyways)

Yes I also have a tee so I can use it for both and would the carbon not remove the chloramines??

Chloramine is a different form of chlorine. It is more difficult for traditional carbon to remove.

If your TDS is 700 and your membrane is dead after a year, your prefilters are not adequate.

I use spectrapure and my RO membrane is still giving me 1-2 TDS (before DI) after FIVE YEARS. I have heard of them lasting 10 years. I change my pre-filters every 6 months with 130 TDS but I would do it more often and probably get some more stages before that RO membrane if I had 700 TDS.

I do 100% on my 5g pico all the time. I just match salinity and temp. I would probably do 50%.

Looking into adding 2 more stages and buying the chlorine carbon blocks thanks for all your help and insight! I'm planning on doing a 50% WC tomorrow after noon. And then probably a series of 10% water changes every other day for a a week or 2. At least that is my plan may be Abit much but I want to try and cycle as much of that water out as possible or at least dilute it.
