there are several reef applications on the market for the Ipad, below is a list. Has anyone used any of them. looking to get something just to keep records as well as other features. The app Reef Calc seems to be all inclusive, however at a cost of $18.99 it seems a bit pricey. Out of the others, Reef Tank Pro seems to be a better choice, however it is new on the market. Any opinions ?
