Mixing membrane sizes

[Shameful1]

New to the forum and the RO process. I put together a RO with 3 300 gpd membranes. While putting the membranes in the canisters one of them was damaged on the bottom and would not seat in the canister. I have contacted the seller and waiting on a response. I tried purchasing another 300 gpd membrane and have now been told they are sold out and would I like either a 200 or 400 instead. My question is, can I run 2 300's and 1 400 in series? If yes what kind of performance difference would I encounter? If it helps I am using an Aquatec 5300 series pump with a 1.7 gpm flow rate.

Thanks, Steve

Put the 400 gpd membrane first, and it will be perfectly fine.

*D. Roseum, Thanks for the quick reply. Will do if I can't get another 300.

Thanks, Steve
