Hey y'all! So I have a moor with columnaris, and my orange looks like she is getting it on her wen, went to a local family fish place, very helpful, they sold me the tetra lifeguard tablets, 8 tablets a day, emptied the carbon out of filters, upped the filtration and air bubbles/oxygen...hope it works, but as I read more, I see that lifeguard may not be the right treatment? I did a 25% change with conditioned water Broderick staring treatment, tested my nitrates...0 , so not sure what I should , stick to lifeguard??
