Terra Aquatica (GHE) pH Down Dry Powder

GHE pH Down powder.

Contains nitric and phosphoric acids and organic regulators

Unlike the pH regulators generally available on the market, GHE pH Down is not a common acid. It is a precise formula that regulates, feeds, and buffers your nutritive solution all at once.
Together with a balanced blend of acids, GHE have incorporated buffers to stabilize pH and help control Calcium in hard water situations.

Ph up and PH down are dangerous together and must never be mixed.
