Olympus Up 25 Gallon (2Cs)

One of a kind in the industry. Olympus is derived from micronized limestone designed to not only raise the pH of your nutrient solution, but also to buffer organic acids from healthy soil decomposition. The calcium in Olympus is also very effective at tying up salts in the medium. Olympus is a key component to the line by adding even more calcium for the plants to absorb.
