  • Co2 Drop Checker Solution | NilocG Aquatics | 4dKH/Ph Reagent For The Most Accurate Monitoring of Your Planted Tank Co2 Levels

    One of the common concerns among hobbyists just getting started with high tech setups is achieving adequate co2 without causing harm or stress to their fish. As a general guideline, most aquarists can agree that 30ppm of dissolved co2 is where we want to be for out plants and fish to thrive. But how do we know if we have too much or too little?   A glass drop checker with a standard solution is by far the most reliable way to have a visual representation of your co2 levels without all the guesswork. It is also the most straight forward. When the solution is blue, you need more co2. If its yellow, you’ve gone too far. If its green, you’re good to go!   Indicator solution kits on the market have their downfalls. Some fail to change color or can be difficult to read. This is because they recommend using water from your tank to create a reference solution, and as most of us know not every tank represents a standard value!   With NilocG Aquatics all in one co2 inidicator solution, your systems water hardness is taken out of the equation. This solution is calibrated to 4dkh and will provide the most true and responsive indicator solution on the market.
