Is It possible to use too much Prime when conditioning water ?

I know it would waste money but can too much hurt the shrimp?

With shrimp being as sensitive as they are to their environment any overdosing of a chemical or chemicals can be potentially harmful/fatal.

Are you asking because you did or because you have a reason to? Using more doesn't over correct, so I don't see why you would. Extra sodium thiosulfate is not good for shrimp.

It's just hard to measure for a small tank as the directions are one capful for 50 gallons. Also 1 thread is approx 1 ml so was just wondering how careful I should be when doing the small water exchanges required for my tank.

I'm want to give my shrimp a good and safe home. It's difficult to figure how much for a gallon or two of water. That is why I'm wondering if it's possible to overdose?

Get a syringe or a dropper that measures in milliliters or cc (cubic centimeters...ml and cc are equivalent). Then do the math for your ten gallon. A capful is usually 5 ml for prime. I believe it even states that on the bottle.

But is a slight overdose harmful? I usually put water in a bucket without measuring exactly how much is in it. Is it necessary to treat the water like a scientific experiment would be or is close good enough?

I use Amquel+ that uses 2.5ml per 5 gallon bucket. It is very simple to get that as it is how much my standard 3ml dropper sucks in. You use a lot less Prime, but a SLIGHT overdose should not be a problem. Just don't double or tripple the dose. By my measure 7-8 drops=1ml.

They have no way of knowing exactly what the chlorine or chloramine levels are in your water supply. so they are a little conservative in their dosing.

Thanks That helps a lot
