Hey guys, anyone know if its possible to upgrade my 75GPD to a 90 GPD Rodi filter? is it possible to swap for a 90 GPD membrane or will I require different housing for it?
Possible To Upgrade Rodi From A 75 To A 90 Gpd?

The membrane should be interchangeable, but you will also need a new restricter/flush valve for it rated for the new gpd.
Edit: actually, 75 to 90 has the same re stricter I think.

sweet I did it right lol Thanks Torx I forgot to mention that I bought the 90 GPD flow restrictor as well as the membrane..... but wait should I have the flush kit as well?
You are set if you have the flow restrictor as well.
The flush kit extends the life of your membrane. You do not need to upgrade that if you have one already. Brs' restrictor is 2 in 1 flush and restrictor.

OK so figured it all out. A bit of a PITA but its done now lol... OK so those of you upgrading your rodi listen up! When you upgrade you gotta change your flow restrictor this is inside of the yellow tubing on the exit off of the membrane. Now theres two ways of doing this.... 1 the easy way buy a precut flow restrictor from jlaquatics or buy a adjustable one from reefsupplies the adjustable one is trickier but more accurate. It involves some timed measurements and cutting back the wick 1 inch at a time and measure product water and waste water. Heres a link to a video and a helpful thread I found. http://www.3reef.com/threads/did-you-adjust-your-new-ro-filter-flow-restrictor.82812/
