Formalin?
https://www.apcpure.com/product/form...SABEgIhJ_D_BwE
This looks rather like the formalin I’d normally buy? Ingredients are;
Minimum Assay: 36.3-36.9%
Molecular Formula: CH2O
Molecular Weight: 30.03 g/mol
Formic Acid: <0.05%
Methanol: 6.0-8.0%
Ash: <0.01%
Iron (Fe): <2ppm
Copper: <2ppm
Am I missing something obvious, I’m no chemist so would be interested to hear from someone who knows more than me about these things

Yes it’s the same stuff. Some branded formalin for koi is 30% though so you would need to adjust the dose down for this as it’s 37%.

I’ve got 13,243 gallons if I treat, FMG for 3 doses means buying in bulk is a fact of life
Thank you for the reply, you might have just saved me a fortune
