Re: [GSAS-Member] GSAS-Member Digest, Vol 66, Issue 50



The CO2!

I just turned it up yesterday and I have no bubble counter on this tank to gauge it.

Water change was after.

Subject: [GSAS-Member] Albino Plecos in Trouble

Hi all,

Came home from a walk around Green Lake and both of my adult Albino Ancistrous are on their backs breathing slowly. The tetras and cories and shrimp are all fine. I just did a water change of 50%

What could cause only the plecos to suffer?

Thanks
Shango


Did you do the water change *before* the fish showed stress, or after? Did you drop the temp abruptly? Or suddenly raise pH?



If the water change was before the fish stressed out, its due to the water change - either a temp change, ammonia spike, or an increase in the chlorine/chloramine level in your water, which may happen if the town decides to mess with the municipal water system.



What kind of dechlorinator do you use? I'd measure the ammonia level if you can, or add some aeration. If you've got some poly filter and can arrange for the water in the tank to circulate through the poly filter, I'd do that. It rapidly removes excess ammonia.



Also, if you have a CO2 injection system, make sure its not excessively dumping CO2 into the tank (like its stuck open or something like that.) I'd even turn it off just to be safe.



Tetras don't mind really acid water and are tougher than you'd think. I've had zero luck with the various albino ancistrus that are circulating around the club, because I think my waters too soft, and I'm not sure that seattle water isn't much softer. I don't think they like low pH.
