Dymax Co2 Indicator

Dymax Co2 Indicator is used to monitor CO2 and pH levels in planted aquariums to ensure the health of plants and fish.

Never fail to monitor your CO2 & PH levels in aquarium by using this indicator. Monitoring co2 levels in your planted aquarium is very important for the health of your plants and fish. This kit is complete with everything that you will need. It includes: High quality drop checker and suction cup.

Extremely simple to operate CO2 drop checker.

To use simply fill the drop checker half way with the Co2 Indicator Solution. Place suction cup on the drop checker and place in your planted tank. Wait 2 hours to read Co2 levels.

How to Use a CO2 Drop Checker

When your co2 is off the drop checker solution will be a deep blue color. After co2 has been on for around 2 hours you should notice the color change. Optimal co2 concentration will be at 30ppm which will be a green-light green color. If it remains blue your co2 is too low. If the color turns yellow then your levels are too high and may harm your fish.

*Please note that you require a CO2 Indicator Solution, sold separately.

Do not buy
Color: Green/Black
Do not buy. When I received the watch it did not work and the battery was dead. I bought a new battery and it killed that one as well after about a month.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.
