Pink fish tank??

[daginge]

Help my semi-tropical (26'c) aquarium has developed a pink tinge to the water, but when I take a bit out to see, its clear, all my nitrates etc tested clear at the fish shop...Any ideas???

Possibly a bacterial bloom. Need moren details of the tank....size, filters, lights, decor, fish etc.

Why would a tank at 26 degrees be semi tropical ?

Hello H, I just thought that that temp would mean semi tropical? Anyway I've sorted it! Never thought at first but, I've been feeding blood worm pellets, so it must be the colourant natural or otherwise! Having done a periodical partial water change and laid off the pellets it's almost totally gone now!
