How to measure CO2 in your tank? How to check if CO2 level too low or too high? Let us set up a drop checker and find out! Don't forget to leave a like if you liked it!

So wonderful to have people do videos like this, especially those who have lost the instructions and have started the hobby over again and forgot little details.

I have never heard of or seen one of those. Amazing & so helpful. Definitely getting one. Thank you 😊

Good video! Great information, just what i was looking for!

Nice explained!👍

Thank you. Very clear.

Thanks Very Helpful Video

Thank you for the explanation i just finished setting up the basics of my fish tank like a air disc, a filter, plants and a good light source. I had no idea how to put the co2 reader in the tank or what was good and what was bad. Lets hope my plants will be alright though 😅.

Also thanks for this information it helps a lot

Really good video

Thank you!

I love ur vids ur my favorite KZfaqr I’d love to meat u someday

Great video. One think you forgot to mention is get solution that's already pre- mixed.

Will this indicate CO² levels from liquid CO² additive or just the canister?

I'm definitely getting one! Do you suggest any specific brand?

I got a co2 system and a drop checker online the drop checker came in early an I install it and it’s in green but my tank has no co2 it hasn’t come in yet can anyone help me should I install the CO2 system? Or what should I do I don’t want to kill my fish

Why should you replace the liquid indicator every few months? Does it lose it color? I'm an analytical chemistry technician. I don't know what indicator it use, but I won't be surprise it last years. Please, show us a used 'worned out' indicator before and after change of liquid.

Why is my drop checker staying green? My Co2 comes on two hours before my light and it turns off one hour before they turn off 🤔

Hi, how many bubbles/sec should i set for a 125x50x55cm tank tht is 344liters approx.. depending on tank size i set it high like 12bubbs/sec for 6hours daily thru timer and my drop checker turned green as i placed it opposite side of the co2 diffuser.. and last week onwards the fishes in the tank started to die drastically.. my water parameters are all fine.. i installed an air stone for oxygen. So how much do i need to set the bubbs in order to get green i tried 3bubbs, 5bubbs, 8bubbs, 10bubbs none turned my solution green wen i kept on 12bubbs solution turned green but my fishes strted to jump out of tank and some died inside.. now i have switched off co2 frm.2days and just airstone is working.

Hi, does the co2 checker change colour once per colour or it is changing depends on the water condition for a full month?

do have to add aquarium water with solution or solution only??

Does this work even when using liquid Co2 such as API Co2 Booster?

If it goes yellow do you have to change the solution or will it go back to green again if levels drop?

How long will the drop checker last? How to identify when to discard and fill fresh solution?

I have been fish keeping for many years now. I do have planted tanks that I do inject CO2 into but I never use a drop checker. To check my CO2 levels I monitor my PH and KH, I measure the Ph levels in the tank to know what my CO2 levels are. Personally I hate drop checkers and find them to be useless. With a KH of 5 I look for a PH of 7.0 for my CO2 levels. To measure my PH I use a Blue Lab PH pen. My tanks PH usually sits around 7.6 to7.7 without CO2 and I slowly bring it down to 7.0 with the CO2. That's it.

How low do u hang the c02 checker?

Kindly tell me if dark green is good? Or should it be light green?

ur co2 is flowing all around so cool, but then theres mine it just goes up in a straight line

Do you have to change the liquid that goes inside the CO2 drop checker often?

How do you do with drop checker during waterchange?

Can we stop DIY CO2 method at night time?

outdated information drop checker is not accurate it all takes hours to change color
