RODI replacement help

[dbleoh7]

I bought this 6 stage RODI 10 months ago and I think it's time for replacement.... The filters look brown and I'm getting algae along my sandbed so I think the TDS must be creeping up... I'm terrible at RODI anything so could someone point me in the right direction on what to get to replace these? Thanks!

You can get the same stuff at (BRS) bulkreefsupply.com because they bought marine depot out. They have it all. Call them if your unsure.

Don't know if you solved this yet, but... the way BRS usually sets up there's is

Stage 1 (Sediment filter) 5 or 1 micron
Stage 2 (Carbon Block filter) 5 or 1 Micron
Stage 3 (same as 2)
Run to tee with pressure gauge
Run to tee with 3 point tds meter (sensor 1)
Stage 4 RO membrane
Run to tee with 3 point tds meter (sensor 2)
Stage 5 Mixed Bed DI resin (BRS standard resin)
Stage 6 same as Stage 5.
Run to tee with 3 point tds meter (sensor 3)

Let me know if you have other questions or need links or how to know when to change.
