Hi All

I have noticed on my Doitsu Sanke and Tancho Sanke that their white looks pinkish not as white as always.
The only difference i have made recently is their food change, i have been mixing their normal Shogan with Aqua Master (Growth ) as i have added a few little ones to the collection.

My water is ok all tests shows good the only thing thats out is the water shows Very Hard and the alkalinity shows low.

Any tips on getting my fish white back
