Ive just changed my lfs my local lfs is terrible ive found one thats not too far away that im pretty impresed with ,the owner talked to me for about 30 mins which is 100% more than the last lfs did. the only thing he said that im not to sure about is that he recomends this special (blue in color) salt that he say's will keep my fish healthier and disease free he say's it will also give the fish a better slime coat which i guess is one of the reasons that there less likely to get any diseases? what do you think ? he wasnt pushing it too hard just telling me he uses it and loves it.
