I am treating my tank with Nematol as I have an EBJD which had white poo. It is an internal parasite/worm teatment. It tells me after 2 days to change at least 80% of the water. Does anyone know why this is an is it essential to perform such a large water change? I use RO water and it takes about 3 hours just to fill 30L and I have a 350L tank!
Thanks.
Thanks.
