Ok, I read on another site that salt can cause burns/discoloration on fish when either too much is used or when not dissolving salt before use.
But the ICH lesions is still a possibility...
Did you dissolve the salt first? Glad to hear that the marks are fading.
Hmmmm... Something to ponder.
Is the reason for the less but more frequent water changes to keep the ammonia from building up without disturbing their balances?
Yes, multiple smaller are IMO
better than larger one-time PWC
's, except in emergency cases.
I see you have a uv sterilizer chilerelleno. How does it work in the fish world? I use one for purification of my drinking water but have been curious of it in the fish aquarium. What is your experience with it?
Sterelizer does just what the name says, it uses UV
light to sterelize the water of free-floating algae, micro-organisms, pathogens and the like.
It doesn't affect your tanks bio-bacteria becuase they are attached to everything, not free-floating.
I've two dirty/wasteful fish that I dearly love in my 75g, and all their poop/leftovers was putting alot of nutrients for algae to grow off of, and I wanted to cut the chances of disease as much as possible.
Since I put the UV
sterelizer in there I haven't seen a hint of algae.
There is a good article about UV
sterelizers here at AA in the Freshwater Articles section, just look on the homepage under articles.
