More Re: Cardinal gill problem 11/13/08
Hi Scott,
Thank you for your response.
<Welcome Wendy.>
I haven't added anything new for quite some time. No painting or spraying of any kind is allowed near the tank, not
even to clean the glass. I use a refractometer to test my SG and it's been calibrated with RO/DI water. Since he's acting normal otherwise I'll wait for a response from Bob.
<I will drop this in his box right now. He is only a day or two out at
this point.>
Thanks again,
Wendy
<Thank you, Scott V.>
<<Most "cases" in which there appear to be "hard breathing", more or less permanent distension of gills are due to issues of gas distribution (low DO mostly, Dissolved Oxygen) or some sort of in situ poisoning... I see that there is appreciable Blue Green Algae present in this system... this might well "be it" here. Please see/search WWM re BGA et al. toxic effects.
