OK, it is coming up to about 6 months for my sediment and carbon block filter. So in theory the filters should be replaced every 6 months. However, I was running the numbers... I use 5g of RO/DI per week, thus about 22.5g per month. In addition, I use 20g worth of RO/DI per month for NW. Thus...

Okay, I received an email message today from Pet Solutions about specials on Aquarium Cleaning Products. Well, it had a link to this product and I just had to take a look at it. Obviously curiosity got the better of me. :) I am wondering if anyone has ever seen one of these in person or even...

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...

before I go and buy a RO unit whats the requirements, (as in what do I need before I go and buy one like some uncontrolable money spending fool) to set one up and which one should I buy? Tired of buying water from the LFS and keep getting water with sand and diatoms growing on the sides of the...

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...

I was wondering how many of You have replaced the RO membrane in your RO units in the past. Not the other Cartridges just the Ro membrane

what is the pH of ro/di water suppose to be?

I just got a TDS meter last weekend and realized that my RO/DI hasn't been hooked up correctly for months, so I've essentially been putting tap water into my tank! :eek: The membrane wasn't pushed in far enough, so there was only a 10 point drop between the tap water and the filtered water...

Hi. I'm connie's husband, Scott. I'm installing her purely H20 optima vision series ro/di system. If anyone has experience with this hook up, please help. There's a black tube and a white tube coming out of the ro membrane. Black is for waste, what is the white for, the float valve...

i have 55 gal.

Does anyone have any advice where to find a good deal on an RO/DI unit for my house? I am tired of going to the grocery store for water. I want to be able to use it for my in-duct humidifier (misting type), my tap next to my sink, and (duh) my tank. My tank is 125 w/100G stock tank. I'm...

Well, I have had my RO/DI unit for about 4 years, and no matter how I dial it in, or replace the cartidges, I can't get a TDS reading below 34 anymore. So it was suggested the the membrane is starting to go bad. If it is the membrane going bad, it was also suggested that in some cases, it is...

Any reason why i couldnt use treated tap water for quarantine. While replacing my ro/di carbon block filter i dropped the housing and it cracked:doh:
