Sometimes, an item is NOT on Amazon and I don't get a percentage and it's still linked on this site. After all, I'm not a COMPLETE mercenary bastard LOL

Directions for use:  add 3.5 ox (100mL) of ProForm-C for every 1,000 gallons of total volume of water to be treated. This dosage level produces concentrations of 0.05mg/L of malachite green and15mg/L of formalin (5.55mg/L formaldehyde). As with all pond medications, a large partial (at least 25%) or nearly complete (approximately 90%) water change will greatly improve the effectiveness of the treatment. Remove activated carbon from filters, and stop foam fractionators (“protein skimmers”); do not stop filtration. The treatment should be repeated every 24 hours with a minimum of a 25% water change prior to each treatment. Do not increase or reduce the dosage.  The period between treatments may be shortened to 8 to 12 hours. Observe treated fishes for at least the first hour of the treatment and be prepared to place fresh activated carbon in the filter, restart the foam fractionator and/or perform a large partial water change if the fish show signs of stress (e.g. piping at the surface or severe “coughing”).

Caution: Do not use Proform-C with any other medication. Do not use with sulfinate-or sulfozylate-based water conditioners. Proform-C may permanently stain silicone sealants, rocks, concrete, plastic containers, clothing, laminate counter tops, floors, furniture and carpeting. Proform-C may be harmful to some invertebrates (e.g. filter-feeding mollusks); use caution and observe carefully when treating ponds that have invertebrates.

When you make your purchases via these links you are supporting the work of Dr. Erik Johnson. A small percentage of your purchase(s) is returned to Dr. Johnson sort of like a Discover card. It doesn't come out of YOUR purchase price. You won't pay a cent more. Amazon kicks the pennies back as a finder's fee for lead-generation. But it adds up and it's very appreciated. So, thank you.

But it works another way. Almost nothing you find on the site is untested. Basically I've bought everything I recommend here. From Amazon. And so you'll see my review on Amazon, verification that I did purchase it there, and then the link to the item. And when someone needs my help and I refer for say, Mardel Clout, the link will be to my Affiliate link. So it's mutually beneficial.
