That does sound a right pain and chore to get it all right.

PPf's food is all Coppens which I dont mind at all,used to buy 15kg sacks but that has gone expensive.

Mine are coming on well, they look a decent size but the water is brown with food tannin so cant see then well.
Bought some unbranded food from ebay which tanned the water,contacted the seller who said he had no probs with it and said it was my filter,so have binned that food.
As they are at 22 deg cant change all the water yet so will have to drop the temps in spring time.
There are some nice Matsuba,Ochiba and Shusui.
Not sure if there are Hi Matsuba but the red hasn't fully come out think they may need some daylight but think they will be nice.
