Give your plants the clean water that they deserve!
The Stealth-RO150 is a customized Reverse Osmosis water filter that is capable of reducing up to 99% of most contaminants. This system is designed for use with hydroponic or horticultural applications. Built to give the maximum amount of flow from the membrane while sneding less waste water to the drain, compared to similar RO filters.
The Stealth-RO150 Reverse Osmosis System produces up to 150 GPD (gallons per day) of ultra-pure, low PPM water. This beast removes 98%+ of all contaminants and chlorine without wasting any water. With water waste levels approximately 50% lower than other RO systems on the market, the Hydro Logic Stealth-RO150 is an easy choice.
Choose from a 1:1 or 2:1 waste to product water ratio (both options included with unit). Hydro Logic provides both of these options because water conditions vary greatly throughout the world and one fixed ratio would not work for all conditions.
Choose between the Standard Green Coconut Carbon Filter - or - Premium KDF/CAT Carbon Filter
For chlorine and chloramines reduction for city water. Also for well water for iron, hydrogen sulfide, and heavy metals reduction. Will last TWO TIMES AS LONG - 2,000 Gallons as the standard green carbon filter. Prolongs the life of the membranes. Reduces chloramines, chlorine, iron, sulfur and heavy metals. Bacteriostatic qualities do not allow microbes to breed in filter.
Chloramines are most commonly formed when ammonia is added to chlorine to treat drinking water, making it harder to remove. While our Green Coconut Carbon filters work great for chlorine, the smaller molecule size of chloramines requires additional filtration to ensure your root-supporting microbes are happy and healthy. These new filters ensure full chloramines removal and ultimate root zone health!
I have well water, what challenges can I expect?
Here are the most common challenges when filtering well water:
How does reverse osmosis affect pH?
RO product water can have a lower pH than the feed water. It depends on the level of dissolved CO2 in the feed water. A lowering of pH can ocurr because the existing CO2 in the water, being a gas, passes through the membrane but the alkaline constituents, primarily HCO3 (bicarbonate), are removed as part of the reject water. In the feed water the HCO3 neutralizes the acid-causing CO2. In the product water, with HCO3, greatly reduced, the CO2 is free to combine with the H2O to form carbonic acid: CO2 + H2O > H2CO.
Another reason to question the pH reading is that for any water sample which is very low in TDS it is very hard to obtain an accurate pH value. The worst case of this accuracy problem occurs with de-ionized water but some low TDS RO water will react the same. The sample is so low in minerals that there is no buffer. The slightest absorption or loss of CO2 shifts the pH substantially. The water’s tendency to pick up additional CO2 from the ambient air, even if the test is done on site, can produce a very low false pH.
In reality, measuring the pH of RO water is difficult and not accurate due to lack of any pH buffering the RO water. If the feed water has a lot of dissolved CO2 then pH can drop a few points. But, in the case of a drinking water RO system, a post re-mineralization filter will help neutralize the final product water's pH level. In the case of RO water for horticultural purposes, once you mix a calcium/magnesium supplement into the RO water and then add your nutrients and additives, the final pH can be adjusted and your feed formula should be pH stable.
Why do pH levels come out higher than the source water when running water through a carbon or Carbon/KDF filter?
This is common, there is generally a significant pH spike from the GAC (granular activated carbon) that is mitigated relatively quickly after start up. For some systems, it can take days or even weeks to run enough rinse water to get the pH back to normal. Since it is temporary, it is generally not a significant issue.
How do I properly store a Reverse Osmosis System that won't be used for more than 3 weeks
Reverse osmosis membranes like water to run through them often in order to perform properly. Running water for once a day for a short period of time is ideal, but even once a week is sufficient. If you are not going to use your reverse osmosis system for 3-4 weeks or longer, there are storage procedures you should follow to maintain optimum system performance. Take the membrane(s) out of the system and place in a plastic bag and put them in the refrigerator. A white plastic kitchen bag with a knot tied at the top works well. Take the carbon filter(and in some systems such as the Stealth 100/200 the sediment filter as well) out of the housing and let it(them) dry out. Leave the housings and the caps on the system unscrewed to let them dry out. The purpose of this is to not trap wet filters and moisture in the system so that bacteria will not grow. As an extra measure of precaution, sterilizing using a light bleach or hydrogen peroxide solution to clean the housings, tubing and fittings is a good idea before using the system again.
How do I know if I have iron in my water?
If your carbon or sediment filter appears to be red, maroon, orange or brown in color you have iron in your water. You may also notice that your sinks and or toilets also have this discoloration. See an example image below of a system that was used to filter water with excessive iron levels.
