"Just like with the pH up this product is a no brainer. I heard about Bloom City from friends who highly recommended them and I couldn't be happier!"
"I have hard water around 8 or 9 pH tap, and this brings it down to low-mid 6.3ph with only 5-10ml to a gallon :) Always holds ph at stable levels, a great product!"
"Just what I needed...only requires a small amount, so it will last! Excellent product, only the best from Bloom City."
