The tabs are fresh sealed. As with all dry feeds the MDH applies to unopened goods, then they should not be more than a year, for example, in the closet. Much of the vitamins is then lost yet. The composition of the tabs is already in the product description. So I can save this.
Ok, to the tabs. Contrary to other reviews, this Tabs adhere quite well and also long at the wheel. I run a 270 liter community tank and folders 3-4 Tabs in different heights to the wheels, so that each animal in its "preferred scum" at the feed can. So there is no stress and everyone will have a go. For me, it takes no less than 20-30 minutes to the last remnant is sucked from the disc. For my ground-level fish (Corydoras and loaches) I booklets tab also relatively close to the ground on the wheel. I would throw them to the ground, my biggest loach would up and away with it.
-The JBL Tabs not muddy the waters
-You can be applied to all animals in the necessary water heights
-also used as a ground-dwelling fish for Bodentabs
-Each animal gets its share from (at least in my pool with Cory, loaches, tetras and rainbow fish)
-All my animals take the tabs invariably well received
I once sat down and counted the contents of 60 gr / 100 ml. There are currently 187 pieces, but I have already fed twice. This gives you a rough idea which package size to order is best.
