Review on ROOYLE Backlight PPM Measurement Temperature Aquariums: Advanced Aquatic Monitoring Solution by Will Powers

The water filter brochure said we had something to measure the water quality (I never thought of that). terrible water but I just couldn't believe it when I saw the numbers of our tap water - as you can see in the picture! I've taken various samples to make sure this thing is working: over the max limit) Filtered with fridge filter - 473 (I can clearly see the filter needs replacing) Recently replaced water filtration system - 138 (this has since dropped below 100, so I know it's better) Bottled water - 16 I don't even know what I was expecting, but looking at those numbers I realized I had to make a few more changes. It was pretty easy to use. The PH I haven't used I don't know at the moment when I will use it as my main concern has been the quality of the water and making sure we change those filters. rs when the quality starts to drop. I think for humans a water filter is definitely a great addition as the recommended timing is sometimes different when your water is as bad as ours.
