    Rodi water

    TDS = Total Dissolved Solids. As is... a TDS Meter. TDS Meters read in parts per million = ppm. You'll use a TDS Meter to monitor how well your RO membrane is working, and how well your DI (Deionization) resin is working when you get an RODI system. Russ

    Rodi water

    Ah-ha. Most of our freshwater customers don't use straight RODI water, Rather they use a mix of RODI and dechlorinated tap water. Your RODI will produce dechlorinated tap if you take water out of the system right after the carbon prefilter(s) but before the membrane. Some of the keepers of...

    Rodi water

    Not sure what you mean. Buy an RODI and start making water.

    RODI System

    We are admittedly a bit biased, but here's some things most people would find less than desirable: Unless you have chloramines in your water, why do you want a system with two carbon stages? This system has a horizontal DI - a fundamental design mistake. The ebay listing says 18 oz of resin will...

    How do i know my bed resin filter is bad

    I think you might be confusing "RO membranes" and "DI resin cartridges." RO membranes are almost always horizontal in residential scale systems - their orientation isn't as critical and can be addressed by how the tubing is routed. That other vendor you mention doesn't sell any systems with...

    How do i know my bed resin filter is bad

    You'd get better performance from your DI stages if you: 1. Packed each as tightly as possible - avoid any air gaps/voids. If the resin bed fluidizes you didn't pack it tightly enough 2. Remove those DI stages from their clips and orient them vertically with bottom-up flow through each...

    RO membrane mess up..

    Let's back up a little. Think of your sediment filter and carbon block as a team. The sediment filter removes sediment before it reaches the carbon block, so that the carbon block doesn't clog with sediment. To make sure this happens you need to get filters with the correct pore size. You...

    How do i know my bed resin filter is bad

    A good rule of thumb is to replace your sediment filter and carbon block after six months. A more precise way to maximize the usable life of these two filters is to use a pressure gauge to identify when pressure reaching the membrane starts to decline. This is your indication one or both of the...

    RODI System Help & Opinions Needed

    Nice. This is similar to how I have my reef set up at home. Couple of thoughts for you: 1. Each drum, when full, will weigh about 126 lbs. Be extra careful with how you set up the shelving! 2. As a failsafe, drill a hole in the side of each near the top, screw in a 1/2" fitting, and attach...

    RODI System Help & Opinions Needed

    You said it. Commercial posts are against the rules! Almost 15 years of experience configuring RODI and RO systems for the aquaculture trade has provided lots of opportunities to try various things and learn what works and what doesn't. There are sooo many systems out there that are...

    RODI System Help & Opinions Needed

    I changed some of what you listed below. Build Your Own RO System Stage One 1 Micron Sediment Filter Stage Two 0.5 Micron Carbon Block Stage Three No need for a second carbon block unless you have chloramines in your water. So a 4 stage system is a better bet for nearly everyone. Stage...

    RODI System Help & Opinions Needed

    If you haven't made your purchase yet, we'll recommend you don't get the ebay system. You can do much better. You want better prefilters than that system comes with. No need for two carbon blocks unless you have chloramines in your water. You probably don't. Email us if you need help...

    Damage rodi membranes?

    High pressure (within the range that you'd get from any residential faucet) will not harm the membrane at all. The weak link in the chain in terms of being able to withstand pressure is your clear housings. You should have a pressure gauge on your system! Russ
