My water pH is extremely high, will this lower the pH of the water?

Answer by Chewy • May 04, 2023
Using a RODI unit does not guarantee a lower pH. It will depend if the supply water has CO2, or high ion content in it that would determine an imbalance of H+ or OH- in the water.

Not obvious in the description, but the manual clearly states that if your city water supply uses chloramines for treating the water, it will damage the filter and another filter (about $50) needs to filter it first.

4 stage ro/deionizer

Works perfect for getting pure water for my new biocube 32 gallon saltwater tank. Takes a bit to go from a slow drip to a trickle but that's expected with new filters

Works perfect for getting pure water for my new biocube 32 gallon saltwater tank. Takes a bit to go from a slow drip to a trickle but that's expected with new filters. Measured water with my tds meter and measured all zeros across the board. Definitely worth the money!

I was setting the filter up to use for the first time. The instructions say to unscrew the big white canister which holds the TDS filer. Upon opening it it was empty. There was no TDS filter in the box either! How am I supposed to use this if all of the filters aren’t included…

Produces more wast than clean water

When I received this item I followed the directions exactly after setting it up and drawing the filters for 30 min as described on the directions I seen it produced more wast water than it was filtering. I was disappointed because I dislike wasting water system is very slow and I don't think I'll be returning I'll look for other options.I really wanted this to work because it fit my budget.
