    Hey all... I've found my RO/DI system (Kent Marine 24GPD) that I thought got tossed, and its been sitting in storage for the past 3 years. With water in it. I know nothing about the unit other then what I've found online, and have no clue what I need to do to get it working again. I tossed...

    I have a Deluxe Kent 35 gpd Hi-S R/o di unit. http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+4395+4453&pcatid=4453Since I received the system I have been unable to get more than 5 gallons a day out of it. I just purchased a TDS meter and saw that my TDS prefiltration is around...

    I've had my RO/DI for 3 years and haven't ever changed any of the cartridges. (bad me!) so my tds is now 2 ppm, and I guess its time for a change. I know it needs a DI because the thing has changed color, and I've never changed either of the sediment filter/ carbon - might want to do that too...

    I have an old ARS Oceanus 100 GPD that needs a new membrane. I can't seem to find a membrane online rated at 100 GPD. Any ideas? TIA!

    Ok, so I only needed to fill two DI cartridges, I ordered 5 lbs of media:confused: Do I just double bag the stuff and save it? It will take a couple of years to use up this amount. It is moist in the bag so I am worried about mold or drying out. How long can I store it or are the folks at our...

    So I finally replaced all the filters in my 5 stage RO/DI after running it for 2 years. I hope I don't have to do that again for at least another 2 years...what a pain trying to find all the little leaks and stopping them. After I got all the leaks stopped it only took about half a gallon before...

    Hey all, I purchased an ARS RO/DI unit a couple years ago. It was a four stage unit (three cartridge chambers and an RO chamber). It's been in the garage for over a year, and some of the chambers still had water in them. So, knowing that all the cartridges and membrane are shot I'm looking to...
  12. Skimmers & other filtration
    I'm about to purchase an RO/DI system, and plan on using it exclusively for my tank, and perhaps the pre-DI, RO water for drinking. I will not use 100 gal/day. From my reading, it seems that a 50 or 75gpd RO membrane will yield higher quality water with a lower TDS. Here's where my...
  13. Skimmers & other filtration
    Hello: I got a new membrane today from Filter Direct. It is a 75 GPD membrane and looks to be working just fine I think. After 3 hours making water I am getting 5 tds after the membrane before the DI resin. I have not tested it after the resin but Im sure it is zero. Question is , is 5 TDS after...

    I am looking into gettin an RO/DI unit and have been doing some research. my only concern is the amount of waster water and i have read something on this forum about pumps that push the waste water back through the filter again and decrease waste by 80%. wondering how many people have had...

    I am looking to buy a RO/DI unit. I want to get one that is most efficient. To me efficient means less waste water per gallon of filtered water. From what I am hearing, the RO/DI units with a higher GPH are "more efficient" (i.e. less waste water) I am also reading that the size (length...

    I've had this hammer for about 2 months and it was only occupying the one little end of the skeleton when I bought it. It has been very green and polyps extended well up until about 2 days ago. I think its dying but have no idea why. I have moved it a few times - mainly because it is shaped odd...

    Where do you all buy them?? I have been going threw them quickly with this water problem we have there :( I have been looking online and ran accross some nice sites for filters. But looking for suggestions to where to buy in bulk like 10-15 filters maybe 20 at a time of sediment/carbon. Now...

    I have the Ocean Reef Plus 1 by the filterguys. I have had it running since about March. Over a few months I noticed my quantity was decreasing and so was quality. I called the filterguys and they suggested that I change out all three cartridges and changed all the resin. My quantity was...

    My ro unit is rated for 24 GPD. If I get a new membrane rated for, lets say, 50 GPD, would that work or do I need to get a whole new unit all together to get more water out of it? Or can I make modifacations to it to recieve that stronger membrane? Thanks
