Has anyone ever heard of Seachem SulfaPlex? The only pages that appear when I google it are in russian or spanish!
To make a long story short, I bought fish 2 weeks ago which happened to be sick and introduced what I'm pretty sure is Columnaris. The owner of the store accepted to give me the medicine for free. What they had in store either didnt work for columnaris, or would have killed my shrimps. So they gave me Seachem SulfaPlex, which both the owner and a salesman appeared to know very well and assured me it was my best choice and would be safe to use in the aquarium. I dont usually use products I dont know, but this seemed like the only option, I wanted to do something to stop more fish from dying, and I have enough trust and respect for this store and for the owner, so I am willing to take their word for it and try this product.
It's just very weird that there is no reference about this product on the internet!
