After consultantion with friends I’ve started to treat the tank with Waterlife’s MYXAZIN broad spectrum bactericide to prevent any secondary bacterial infection. This is a five day course, I’m not sure but I think the area of ulcer is receding.
I’ve like to try Furan-2, but it’s not available in the UK!
I’ve just finished painting another three 30x15x12 fish tanks and they have been test filled in the sun (yes, unbelievably it’s not raining yet!), to check they don’t leak.
