The glass body fixes to the tank wall with the cup, and the checker monitors the CO2 level in the water column continuously. The set weighs 65 g (2.3 oz) and is listed for fish tanks.\u003c\/p\u003e\u003ch2\u003eA glass checker that shows the CO2 level by colour\u003c\/h2\u003e\u003cp\u003eThe checker is made of glass and works with the supplied 4dKH\/pH solution. It stays on the glass and monitors the CO2 level in the water column continuously, so the reading is there for as long as it is fixed in place.\u003c\/p\u003e\u003cp\u003eThe colour of the solution is the reading. Blue means more CO2 is needed, green means the level is sufficient, and yellow means there is too much CO2 in the water.\u003c\/p\u003e\u003ch2\u003eDoes this drop checker suit your tank?\u003c\/h2\u003e\u003cp\u003eThe manufacturer gives one hour as the waiting time before a reading counts, so the checker needs to stay fixed on the glass for at least that long. It mounts with the included suction cup rather than with a bracket or a clamp.\u003c\/p\u003e\u003cp\u003eThe kit holds 15 ml of 4dKH\/pH solution, and the directions use that solution at half the capacity of the checker, so the bottle covers several fills. The yellow reading marks the point where CO2 is too high, and the green reading is the sufficient level the manufacturer describes.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eCO2-Testkit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem form\u003c\/th\u003e\n\u003ctd\u003eLiquid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget audience\u003c\/th\u003e\n\u003ctd\u003efish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem weight\u003c\/th\u003e\n\u003ctd\u003e65 g (2.3 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSolution volume\u003c\/th\u003e\n\u003ctd\u003e15 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCheckers included\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSuction cups included\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat is in the box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOne glass CO2 drop checker\u003c\/li\u003e\n\u003cli\u003eOne 15 ml bottle of 4dKH\/pH solution\u003c\/li\u003e\n\u003cli\u003eOne suction cup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuestions buyers ask about the drop checker\u003c\/h2\u003e\u003ch3\u003eHow much solution goes into the checker?\u003c\/h3\u003e\u003cp\u003eThe directions are to fill the drop checker half full with the provided solution, which leaves the rest of the glass for the air above the liquid.\u003c\/p\u003e\u003ch3\u003eHow long until the colour means something?\u003c\/h3\u003e\u003cp\u003eYou check back one hour later for an accurate reading, so the colour seen sooner than that is not the reading the manufacturer describes.\u003c\/p\u003e\u003ch3\u003eWhat do the three colours mean?\u003c\/h3\u003e\u003cp\u003eBlue indicates more CO2 is needed, green indicates sufficient CO2 and yellow indicates too much CO2.\u003c\/p\u003e\u003ch3\u003eHow does the checker stay on the tank?\u003c\/h3\u003e\u003cp\u003eIt is affixed to the glass, and the kit includes one suction cup for that mounting.\u003c\/p\u003e\u003ch2\u003eHow to use the glass drop checker\u003c\/h2\u003e\u003cp\u003eFill the checker half full with the provided 4dKH\/pH solution, then affix it to the glass using the suction cup.
