Reverse osmosis is a water purification process that uses a membrane to remove ions, molecules and larger particles from drinking water. This in effect creates a pure water source from which we can add buffers to create water to any specification for our shrimps.
This is done by adding salts of some sort to the water, these buffers are species specific so you will need a different one for Neocaridina and Caridina and other types of shrimp. To
measure the amount of buffer you need to add to the water you will require a TDS meter, TDS stands for Total Dissolved Solids.
For Bee shrimp, I like a TDS of 150ppm
For Neocaridina I like a TDS of over 200ppm
Remember all water needs to sit and age for at least 24hours before going near a tank.
Once you make the switch to Reverse Osmosis chances are you will never go back to using ordinary tap water and really why should you?
HOW DO REVERSE OSMOSIS WATER SYSTEMS WORK?
Reverse Osmosis works by forcing water through a membrane that allows some things through but not all things, Typically the size of the holes in a membrane range from 0.1 to 5,000 nm depending on the brand.
Think of this process like you would if you were sifting a bag of rubble what you keep goes through the holes while waste is left on top and discarded if you have a TDS which you should have if you own a Reverse Osmosis Unit..you can test this.
- First, test your tap water as a rough guide I will say mines is 50ppm.
- Second test your clean water outlet, this should range from 0-10ppm
- Third test you waste water outlet and see what you get for me its normally around 100ppm.
What about Reverse Osmosis Maintenance?
I will list this in order of what I do because it will make more sense for you this way, let’s start of with the sediment filter these need to be replaced every 3-4 months because they do clog up and become chocked ..tap water is much dirtier than you think and if you ever decide to cut up an old sediment filter I am pretty sure you will be shocked.
Your Carbon filter should be changed again every 3-4 months, I like to run two of them inline on my system so It never gets to the point of failure.
The RO membrane itself can last for years and I change mines out every 3 years or so, they will last longer if you protect them with regular filter replacement in front of it.
New Reverse Osmosis Unit And High TDS
This is very very common in new systems as I think some of the carbon dust from the carbon filters is able to pass through the RO membrane, to fix this all you have to do is let your RO unit run for an hour before you start to collect that water.
