Review on 🔬 OptiCO2 Drop Checker by NilocG Aquatics by Corey Krull

I use and love NilocG fertilizers so I decided to try their CO2 drip test solution. I am disappointed and will most likely try another brand afterwards. First, the solution was unsealed and leaked during shipment. I wanted to trade it in but with 90% left I decided to just keep it and use it. I thought the rest of the bottle should last for a while but I was wrong. This solution is lightweight so you need to use more in the checker. Then after a few days it loses color intensity and after about a week it becomes completely transparent and unusable. All other brands I've used in the past have had no problem maintaining color intensity until my dripper is covered in algae and needs to be taken out for cleaning (every 6-8 weeks). Those decisions never become so clear.
