Neutro Bromo Blue For CO₂ Drop Checkers - 100ml

    Description

    Neutro Bromo Blue solution can be used with all drop checkers and is the only solution you should be using in a drop checker. Does not require mixing or anything else.

    Directions: Add a few ml to your drop checker, then pop the unit directly into your aquarium and wait to see the colour change. Ideal colour to aim for green. Blue means too little, yellow means too much. Adjust your CO₂ output accordingly.

    You may also want to consider the 3ml Pipette which is used to dispense the Bromo Blue liquid into the drop checker. If your drop checker stays blue you simply need more CO₂. Simple as that.

    A ready-to-use CO₂ indicator solution for drop checkers that customers praise for convenience and value. "Very distinct colour" with clear CO₂ detection. Some shoppers note the colour intensity can be hard to read or fades quickly in checkers. "Does exactly what it says on bottle" with no mixing required. Large 100ml bottle offers excellent value.

    • Very distinct colour, much better than JBL that I have been using previously.
    • I tried this alongside my regular drop checker solution and it works exactly the same.
    • The best indicator on the market and the amount will last you decades.

    What can I say, it’s blue and changes colour when detecting co2 levels! Also bought the glass drop checker from aqua essentials which is way better than the one I had, the glass ball allows light to enter from all angles so you can clearly see the fluid

    Works well, no batteries required. I find the colour very intense and not too easy to read. Wonder if it could be diluted?

    Easy to use. Works out of the bottle. I recommend you pick up a pipette to use it with most drop checkers. Would be ideal if one was included. Otherwise very happy with it.
