Description
ANS Drop Checker measure accurately the amount of CO2 in the water. Opti glass material used enhances elegant visual effect to your planted aquarium.As all planted aquarium are different, the amount of CO2 intake by plants are different. To measure accurately if the amount of CO2 is enough, we use CO2 monitor device. CO2 monitor device accurately measure the amount of CO2 dissolved in the water.
ANS Opti Glass CO2 Checker Set for Planted Tanks
A drop checker is the simplest honest read on how much CO2 your plants are actually getting, and this Opti glass set adds a clean, near-invisible look to a display scape. You fill the small chamber with the indicator solution and hang it in the tank; the colour shifts with dissolved CO2, giving you a rolling visual cue rather than a single-moment test. For the high-light planted tanks popular among local hobbyists, that feedback is what keeps growth strong and algae at bay.
Read it an hour or two after lights and CO2 come on, and adjust your bubble rate gradually toward the target colour rather than chasing it instantly. Because the indicator lags real-time CO2 by a couple of hours, treat it as a daily trend, not a live gauge. Refresh the solution periodically, and never crank CO2 hard in a stocked tank, since our warm water holds less oxygen and fish stress shows fast.
