Colombo CO2 Reactor REFILL

Since I swapped out the old canisters for these refill pouches, my plants have never looked greener. The two-bag system mixes cleanly with tap water, and the CO₂ production is steady for weeks.

Didn't realize I needed both pouch A and B until I read the reactor instructions, but the two-bag setup is actually simple once you get going. CO2 output picked up within a day of refilling, and my plants have been pearling every afternoon since. Cheaper than swapping cartridges too.

Mixing the two pouches with tap water took maybe a minute, and my reactor had steady CO2 bubbling within a couple hours. Each refill pack lasts a good while in my 60L tank, so the two-bag setup works out cheaper than I expected.
