Negative: - buzzing in the aquarium more than ne ordinary air pump which man hardly hear.
- Installation - much more complex than the conventional air hose with vent !!!
What is not seen on the product photo:
The Bubble Maker has a low-voltage cable with a power supply at the end and the second
an air hose from Ca.1m length (as in the conventional Aussströmer), which are connected to the Bubble Maker
and externally must be performed !!
So double installation effort, since one must lead cable and hose to the outside.
Supplied but are cleaner with double-mounting it.
Conclusion: A conventional air hose with good air stone is easier to install and is also quieter circumstances.
If the hum would not - a good product
