About this product

The FZONE aquarium CO2 drop checker kit contains one glass checker, a 15 ml bottle of 4dKH/pH solution and one suction cup. 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.

A glass checker that shows the CO2 level by colour

The 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.

The 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.

Does this drop checker suit your tank?

The 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.

The 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.

Questions buyers ask about the drop checker

How much solution goes into the checker?

The 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.

How long until the colour means something?

You check back one hour later for an accurate reading, so the colour seen sooner than that is not the reading the manufacturer describes.

What do the three colours mean?

Blue indicates more CO2 is needed, green indicates sufficient CO2 and yellow indicates too much CO2.

How does the checker stay on the tank?

It is affixed to the glass, and the kit includes one suction cup for that mounting.

How to use the glass drop checker

Fill the checker half full with the provided 4dKH/pH solution, then affix it to the glass using the suction cup. Wait one hour before reading the colour: blue means more CO2 is needed, green means the level is sufficient and yellow means there is too much CO2.
