Regarding the colony, and if it has signs of RTN or STN, the recommendation that is still prevalent is to remove it from the tank, to fragment the viable parts (if any), to fix them in new bases with methacrylate super glue and to try to grow them in a tank of frags well balanced.Do you think I should just yank the entire colony from the tank? I mean it appears as though it’s a total loss and I don’t want its death to cause some other problems?
What about reintroducing the phosguard? I read earlier in the thread that you said to leave it in the keep parameters in line etc ; but then you later linked to an article that says it can leech the meds from the water? Thank you so much for the response and sharing of knowledge.
Best regards
Regarding Phosguard, there is evidence that aluminum media can fix fluconazole on its surface and help remove it, but for this purpose the best medium is activated charcoal, which can remove almost all the drug from the water column within a few hours , if this is the intention. As a means of controlling the phosphate released by algae death, GFO can be used.
