awesome! thanks Mark!!

there was mention of adding a piggyback membrane to improve your gpd. for future reference, do you know where i can pick one up?

also, if i were to change the membrane size to a 150gpd (i noticed from the links that were provided that some 150gpd membranes have a very good rejection rate) would i have to do anything special to the unit itself?

I have the exact same AquaFX Barracuda as you do. I bought a Flush Kit for my system too. I flush it for about 5 minutes after every use. It's a great little system. Mine is also 50 GPD. I found it great when I had a smaller tank, but for my 90 gallon I am looking at upgrading. After 2 years (or has it been 3?) my 50 GPD RO membrane is finally starting to get used up, so I will replace it with a 150 GPD membrane. Upgrading is simple, buy the 150 GPD membrane with the 98% rejection rate, and buy a 150 GPD flow restrictor. You will find the flow restrictor on the good water line. If you pull the line off it will be stuffed in the end of the tubing. So, just make sure the rating of the flow restrictor and the membrane match and you're good to go!

In the past I have bought from Bulk Reef Supply, but I am going to order my next set from Kelly at The Reef Shoppe as his prices are very competitive.

thanks again myka!!

i will have to check them out...

you mentioned that the restrictor should go on the good water line but http://www.bulkreefsupply.com/store/...-your-membrane says to put it on the waste water line. are the barracudas set up differently?

and one last question... what do you store your water in? do you make up a bunch of ro water? i was thinking about buying a large plastic garbage can and storing the water in there.

Myka,

I check her site out but can't find any filter or Membrane for Aqua FX. Can i just buy any generic filter and will fit?

Thanks
