Why don’t the CO2 bubbles dissolve after reinstallation / cleaning?
After reinstallation the bubbles move only haltingly through the diffuser and sometimes merge into large bubbles. The device needs approx. 48 hours to set up! After that a bio-film will have formed on the surface of the device, allowing the bubbles to rise freely upwards. After the running in time the required bubble count will adapt itself for your aquarium.

Where did my algae come from?
Algae problems in an aquarium can never be traced to just one factor or general condition, and instead, are always the result of a combination of different factors, which include light, fertilization, water changes – specifically, how often and how much – feeding, fish population and, of course, the specific water parameters. _x000D_ _x000D_ According to analyses that were performed over a course of a number of years, red algae, at least the common brush algae and beard algae, occur in descending order at the following parameters: _x000D_ _x000D_ 1) too little carbon dioxide (in relationship to 100 % of the measured tank); the pH level should be in the slightly acetic range, depending on the carbonate hardness, in every case. _x000D_ 2) elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here. _x000D_ 3) too little and too irregular fertilization (there should always be traces of iron at least). _x000D_ 4) insufficient water changes; a weekly water change of over 30 % is recommended for algae problems. _x000D_ 5) not enough fast-growing plants._x000D_

Why doesn’t the thermometer stick to the pane?
Please clean the pane thoroughly before you install the thermometer. Algae, biofilms and lime can prevent it from sticking. If the thermometer still doesn’t hold, there may be a problem with the suction cup. Due to a material defect some suction cups have bubble-like excrescences which prevent a correct hold. If you own such a suction cup, please contact our customer service, and provide a photo.
