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

I hope it is accurate, i put around 20 drops in the checker and put it in the tank about 24 hours ago but still no color change, i had kept the previous checker from azoo in the tank just in case, it kept chamging its color according to the co2 injection but nilocg hadn't reacted so far. O might have put too mucb solution in the checker, internet says 15 drops but there was no onfo on the box, it just said "put the solution in the glass checker 1/3 - 2/3 full" and thats how much i filled it. Also, looking at the advertised solution and the one i recieved, i dont know if this is the correct one, adding a photo of the bottle hoping to receive clarification about it.

Im glad I purchased this for myself as the one I received wasnt in the best of shape. The outer box had gotten wet at some point (this was the only item in my shipment that had any sort of damage), the inner box holding the glass drip checker was completely open, and Im not sure if it was supposed to come with a reference card or instructions as seen online or not, but I didnt have one. There is a chart and some limited instructions printed on the drop checker box that I didnt notice at first and very nearly threw away. I had to look online for information about where in the tank to place the checker, how often to change the fluid, etc. Other than that, seems to be of good quality and should work just fine.

This Glass Co2 drop checker is a valuable tool to have in your tank. It's small and being glass it basically disappears in the tank and is NOT conspicuous. The monitor fluid goes from blue to green when the CO2 levels are proper and with a planted tank now that drop checker REALLY disappears! The drop checker has helped me several times as I was injecting too much CO2 so the green went yellow and even to clear once. I shut my CO2 generator down a day or two and the monitoring fluid went back to green and I turned the CO2 generator back on turning that needle valve down to about one bubble per second. Finally I got the needle valve to where the drop checker was green every day which is where you want to be. Do you ABSOLUTELY need this? No. But for me, it was quite helpful and I'm glad i bought it. Glad I'm using it. On a side note, I notice that in photos of a lot of really high-end Amano type tanks I see these little CO2 drop checkers so I figure if THEY are using them perhaps it would be wise that I use them as well.
