Tank update:
Took a vacation over summer, had a friend come in and look after the tank. Feeding went well but water conditions were problematic. As a result I came back to mild fin rot affecting all of the angels. Normally not a problem but now with no more access to antibiotics through pet shops it’s become more of a challenge.
Working through several options with no luck I eventually went with an extended 3 week treatment of melafix which seemed to do the trick. Fins are showing good recovery growth.
At the same time I’ve added Purigen to both filters - this is experimental. Over the past year, even when the tank was healthy, at any given time there’s always one or two fish that would have part of their pelvic fins missing. It seemed as if fins would get to a certain length and then melt away half way up the fin to a point where it would break off. As you can imagine this was frustrating. I suspect that even though I have been carrying out 30% water changes very regularly (2x per week) the water conditions might not have been optimal. Even with low stocking levels. So I am trying purigen to help lower ammonia levels even further.
So far I’ve been using purigen for 4 weeks and fins appear to be regenerating without sign of decay so early results look promising.
