Used RODI redo

[LAX Noob Reef]

Quick question regarding RODI. So I bought a used spectral 90GD, owner has not change the membrane since 2018, and new membrane he bought back then in a back with 99% rejection rate is very dry. So I tested and no water come out other side at all, which I guess it's gone. So instead of buying new spectral membrane which is about $70, can I use BRS membrane, and add more filter stage to it? or it's not compatible and need BRS can?

I hope you mean spectra pure rodi. If so yes any std membrane will work.
