Is my old membrane fine?

[Fishbro]

Hey so I picked up a used brs 6 stage recently and all filters were old so I replaced them all except the membrane. After a 20 minute flush with all new filters (without di) I’m getting 6-7 tds. I assume this membrane is ok to use? I usually get 320 tds so I’m pretty sure it’s alright but just wanted to check. The membrane is about 8 months old.

It really depends on how much it was used. I get 0 TDS on my new membrane.

Ok so I just ran out of resin and the resin is pretty much to the top will it still work? I have another resin stage and I’ll be buying more will it work for just to make 25 gallons?
