I have a newly established tank (10 weeks old) containing 2 cory's, a pleco, 4 guppie's, 3 molly's, 3 silver sharks and a shoal (10) of neon tetras. I had the water checked last week only to be told my Ph was sky high, not wanting to use chemicals I was advised to remove 3 of my 7 plants and to carry out frequent small volume water changes. Having the water checked yesterday we found the nitrite to be high hence plants back in, and a 20% water change.Today I lost a shark, a guppi and a tetra, the remaining fish are rife with white spot and maybe a hint of fungus.
I went to the retailer they sold me 'King British white spot terminator'. Having administered this I lost another shark and the remaining fish don't look at all happy.
I have now read on the net that the treatment (malachite green) can be detromental to My filter health.
Any advice would be greatly appreciated. Oh No, another tetra has just let go!
Sounds like the treatment has knocked out some of the bacteria in your filter, this is why your nitrites have risen again.
