A few points have me but a little disappointed.
The fountain has not been sealed. At the top cap is 2-3cm long very fine crack at the fountain back exactly where the transition point of the water from the hose into the "rock" is. Through the crack the water is on the back wall downloaded and leaked. The we noticed after a short test run. I have mended the rift with some transparent silicone, which I have applied very thinly.
The fit of the individual components to each other is rather poor. For example, a cut-out for the power cable of the pump at the rear end was allowed, but not for the Fogger. Here, the cable must be led out laterally without acc. Recess, whereby the cover but rather loosely as firmly rests on the site. In light nudge the structure falls apart quickly.
For nucleation I can not say anything yet, but I can imagine this very well. I use distilled water with a small amount of tap water for the fountain and hope that I have thus reasonably under control.
The frogs take the well to very well.
