Hey guys I have a 5 stage RO/DI filter that is 100 gpd, and I was wondering where is the best place to order replacement filters, also what filters to get because this is my first time replacing them.

thanks

Reefgeek has decent prices and sells a whole 5 stage filter replacement kit (http://www.reefgeek.com/care_&_maintenance/Water_Purifiers/Replacement_Filters/5-Stage_Filter_Pack_w!_75_gpd_RO_Membrane_by_Aqua-FX) . 75 GPD is the biggest one they have. It's a start though, you can look at it and see exactly which filters you will need to get if u decide to get it somewhere else.

Well I'm looking on bulkreefsupply.com, but I don't know which filters to get. I bought this from a guy for next to nothing.

It also has a di cartridge on top of the RO membrane.

I really have no idea on what filters to put in this thing.

ttt, come on I know someone knows which filters work great and which ones go into which chamber. Do i want to get the the larger micron filter like a 5 micron filter to a 1 micron filter then to one with a carbon block? to RO to DI?

+1 I have email about 3 Q's and have got'n fast replies, with solid solutions. Asked about doubling up on filters to lessen the load of the RO membrane and they told me not too... that it was a waste of money but to double up on the DI. So that alone saved me a few bucks. I was already planning on doing it any ways and didn't ask about in the email.
