With my ponds you can easily manage the water parameters of your aquariums or ponds.
So you always have the current status at a glance.
Make all the ponds and aquariums you have and choose the type, e.g. Koi-pond and it will load all the optimal settings for the water parameters, this can of course edit later.

With the optional PondCloud you can save your readings online and sync with multiple devices without having to buy the PondCloud there.
