It's my understanding that the dosing recommendations for PPS and EI assume you're using high light and CO2. With regards to EI, it's recommended that you cut the dosage if you don't use CO2 and/or high light.
Zorfox, I think you have the yellow and red CO2 ranges mixed up. It was my understanding that as the CO2 concentration went up, the pH goes down. Given the dkH stays the same.My drop checker is usually yellow lol. You can also roughly calculate the CO2 level based on your KH and PH using a chart like this one.

It's not an exact measure since there are other buffering agents but a good option.
You can also use two drop checkers with different KH solutions. Here is another calculator that explains the process. This will get you pretty close.
LOL you're right. It's not mine. There are hundreds out there just google KH PH CO2 Chart.Zorfox, I think you have the yellow and red CO2 ranges mixed up. It was my understanding that as the CO2 concentration went up, the pH goes down. Given the dkH stays the same.
Whew! I was sweating it when I corrected you. I try not to correct anyone because I'm usually wrong.LOL you're right. It's not mine. There are hundreds out there just google KH PH CO2 Chart.
CO2, pH and KH are all related.So that chart for the ph and kh. If I switch the red a yellow meanings, will that give me an accurate reading about how much co2 I would need. Or Is there a liquid test anywhere or a meter, pen I can buy to measure the amount of co2. I just turned the co2 up this morning it's running faster than I can count and my fish aren't gasping at all.
Don’t let making a mistake dissuade questioning others. I learn more from mistakes and being corrected than anything.:icon_winkWhew! I was sweating it when I corrected you. I try not to correct anyone because I'm usually wrong.![]()
Honestly, I think we concentrate on measuring CO2 too much. Yes, I just said that lol. The fact is, we should raise CO2 until we see signs of distress in our fish/shrimp and then reduce it to the previous setting (or a couple of previous settings if your new to CO2 for a safety margin). This is where our CO2 levels should be and we didn’t use charts, drop checkers or any other form of measure except the flora and fauna. After you obtain this level NOW you can look at your drop checker and/or chart and use them as a reference to monitor for changes easily. Even then the form of measure we should use will always remain our flora and fauna. It doesn't really matter if we can measure with perfect accuracy. Every tank is different anyway so concentrating on a specific measure is less important than watching our fish.What if you use Amazonia, since it's a buffering substrate my kh is 0. I use ro water remineralized with salty shrimp gh+ for my shrimp and fish tank. It's easier to mix one barrel than two. Then my ph hypothetically if it was at 6.3-6.6 my co2 should be in the right range? But what if your ph tests lower than 6.3... Just going off the chart here. I know there all closely related. Same as with gh.
Good idea haha. All I need now is a new canister with better flow to push the co2 around the tank and I'll be setDon’t let making a mistake dissuade questioning others. I learn more from mistakes and being corrected than anything.:icon_wink
