Almost all bottles tell you how to treat 10 gal. But nothing less.. Is is always a ml per gal? (any conditioner?) Or is this just specific to API stress coat?
It's not always 1 mL per gallon. Some brands are more concentrated, others more dilute. But each brand will give you the correct dosing information on their bottle.
To treat small quantities, it's just a fraction of what's needed for the larger tank.
For example: Say you need 5 mL conditioner per 10 gallons water.
This means you'd need 0.5 mL condition per 1 gallon water. (Divide everything by ten.)
From what I've determined, there are ABOUT
20 drops in 1 mL. So if you needed 1 mL, you could add about 20 drops. If you need 0.1 mL, you could add about 2 drops.
(If you want to see if the 20 drop rule applies for your conditioner, you could put drops of conditioner into the measuring cap on your bottle, and count how many it takes to reach 1 mL.)
As for the pet stores, I assume they don't dose each individual cup. They probably have a huge tank of water, and fill the cups from it. :)
