i never used it except once, the first time. I decided I liked uncoloured water
Then i threw it away, as like all meds, it was past its expiry date. I never bought it again. Same for Malachite Green. Now, as an adult, i know Malachite Green is carcinogenic. I cure fungus with salt (non-iodised salt sold in lumps straight from salt mines near the sea, and sold for Rs 4 a kg in village shops, cattle are fed with it occassionally), i cure ick with heat and salt, and the only exception i made was when i bought a bottle of CopperSafe for treating velvet. Rs 225 for one bottle. It was an exceptional thing for me to do, but i loved those three pearl gouramis... they had a shape that i have waited years for! But when i got back, i was got a plesant surprize! my pearl gouramis, three of them, which were covered in velvet, swam curiously towards me as i thought what the right dose of CopperSafe would be, spontaneously recovered!? That was, i later realised, because i switched the lights off and kept them off for a week. Amazing but true. I got this one case of velvet only, that i can remember in the recent past, and i can't be sure it works for all fish, but it sure worked for me, and one fish was totally infested. But today, it is as healthy as it could be, as are its less affected sisters.
So now, i can say i use just salt and a heater (for raising temps, if needed) to cure fish disease. I taught Harmeet Singh, based in Old Rajendra Nagar, about salt and heat, and he told me he cured a tank full of goldish of fungus. So he is another example of 'natural cure' hobbyist.
So if you are a veteran like me (i am in my mid thirties now, and i have over 20 years of keeping fish behind me now, as i mentioned in my introduction), explore the world of natural fish cures and try and keep away from drugs as much as possible. But remember, nature cannot work if u do not give fish enough space to live in, and clean water (good filtration and adequate water changes).
Happy fish keeping guys
