It's not pH that's causing their problems, it's the highly toxic level of ammonia you have in that tank. Do you understand the cycling process? There's something wrong with your biological filter, and it's killing your fish. A cycled tank should have 0 ammonia, 0 nitrite. If it's not, then it's not cycled. The problems you are seeing are related to water conditions, and most likely nothing else. Salt isn't going to do anything right now. You've got to get those parameters under control.
Exactly!...
The Red Tailed catfish and the Tiger Shovelnose catfish, both, come from acidic water probably 6.8
Your LFS just sold you Carbon and salt, when that doesn't work, he'll sell you something to buffer or raise the Ph...when that doesn't work and the fish die, what will he sell you then?
You said the tank has been running for a year, those 2 fish you have there arn't a year and a half old, what happened to the other stock?
I'm wondering why you ask us for help, then, site what your obviously incompetent LFS is telling you.
Something here isn't adding up.
2 x AquaClear 110's and a Fluval 305 on a 125g tank, you have 2 fish, you do
weekly 25% waterchanges, and you just had an Ammonia reading of 4.0PPM, NitrIte of .50PPM and Zero NitrAtes.
then
you stated you do
50% W/Cs every 5-7 days and 12 hours after a 50% W/C you read 1PPm Ammonia
Zero NitrItes and 5PPM NitrAtes...
There is contradiction in your posts, I'm sure it is some kind of mistake
maybe we need to start over or something or maybe ummm well,
you know...
