Prime made my fish sick.

[Leeniex]

So I ran out of the stuff I have been using (Tetra BettaSafe) so I picked up Prime because I figured that's the best stuff. Did a water change on all three tanks this morning, adding the Prime. Withing hours all of my boys were lethargic and laying on the bottoms of their tanks.

Ran to Petsmart and bought another brand and did water changes again. They seem better but not back to normal.

The expiration dat is nex is 2013, I calculated the Prime and used a new syringe to add it. (I'm a medical assistant I calculate dosages). I acclimated the fish like usual, I just don't know what else it could have been.

Just wanted to put this out there in case anyone else has seen this happen.

Should be 2 drops per gallon, altho you can double it with no ill effects.

Wow that is so strange thanks for letting us know, I have been using Prime for months now without any problems sorry this happened to you.

[shellieca]

That is strange, I only use Prime & have never had a problem. Glad they're feeling better.

Bettas can be very sensitive when it comes to water changes and if Prime had ingredients that they weren't used to, then it may have affected them. So, it may not have been the Prime itself, just that they were so used to something else, that it affected them badly.

I will say that I once used Prime many years ago, in 3 different tanks, and fish in all 3 tanks reacted badly, including some deaths. This happened within a short amount of time after doing the water changes. I quickly added a different conditioner to the tanks and everything was back to normal within minutes. It was like the Prime just didn't work or something (not sure if fish can even die from chlorine that fast tho). But I had used much of the same bottle in previous water changes with no ill effects. If it had been one tank I might have blamed myself thinking I had forgot to add it, but there was no way I forgot to add it to all 3 tanks.

Perhaps a bad bottle? Just curious what dose you did use.

[Leeniex]

0.25 mL for 2.5 gal.

I also have well water, so no chlorine. One fish looks okay today but I may lose the other two.

That's very strage butstick with what you used.
I've used Prime for years without any problems, I don't even let my tap water age before I change my fry's water, just doble dose.
Hope your fish make it through

Well, looks like I may loose all three. Bandit was good for a couple of days but took a strange turn overnight and now is close to death.
