How can I remove the hose from the device?
At first the air hoses and special CO2 hoses can easily be pushed on the connection piece. The hoses harden more and more as the months go on and can only be removed from the connection piece using great force. If you pull the hose hard it will only strain the connection, which could, in the worst case, even break off. Instead cut the hoses you want to remove laterally at the ends and carefully remove them. For this it’s always advisable to install hoses with some reserve in its hose length.
Is my SafeStop damaged if I can’t blow through it?
The retaining spring in the check valve fits very tightly and ensures that no water can return. Therefore the air pressure of a diaphragm pump or our breath is not strong enough to open the spring. The valve can be opened by the pressure of the ProFlora bioCO2 systems and also the m and u series. Check valves used in air systems have a smaller counter-pressure and are also part of the JBL range.
JBL ProFlora bio: When does fermentation begin with my BioCo2?
When the CO₂ fermentation begins depends not only on the room temperature, but also on the temperature in the reaction vessel and the starting temperature of the fermentation starter. Fermentation normally begins after 48 h. If CO₂ production still doesn’t occur, as in your case, you could try adding some more of the microorganisms. As an alternative, you can also add approx. the same amount of dry yeast.
How do I clean the reaction vessel of the ProFlora BioCo2 set properly?
It should be washed by hand. The plastic may be damaged in a dishwasher. A washing-up brush, bottle brush or JBL WishWash can be used in addition. JBL PowerClean or BioClean A can be used as a cleaning solution to remove coarse dirt.
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.
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:
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.
2) elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here.
3) too little and too irregular fertilization (there should always be traces of iron at least).
4) insufficient water changes; a weekly water change of over 30 % is recommended for algae problems.
5) not enough fast-growing plants.
What’s the best way to deal with brush and beard algae?
1. Increase the volume of water changed each week to about 30-50%.
2. Fertilise regularly after the water change, e.g. with JBL Ferropol.
3. If necessary add a daily dose of Ferropol 24.
4. If algae promoting nutrients (especially phosphate) are present in higher quantities, use JBL PhosEx ultra to keep them under control.
5. Most important is carbon dioxide. Beard and brush algae are always a sign that there is too little carbon dioxide in the water. If a CO2 system is in use, increase its dosage. Alternatively consider installing a CO2 system like JBL ProFlora u401 or m601.
6. Put in fast growing stem plants as nutrient competitors.
7. If there is strong current, reduce it slightly.
The fermentation starter of the JBL BioRefills won’t take off.
Please bear in mind that the microorganisms are sensitive. They need heat for an optimal start and optimal work.
Fill the reaction vessel with approx. 25 °C warm water after adding component 1. Then add the microorganisms and close the reaction vessel. Shake the vessel vigorously, making sure to seal the opening with your finger. Then place the reaction vessel in the Thermobox (applies to ProFlora bio160). After no later than 48 hours, the reaction should have started.
The Taifun P does not produce any bubbles when used with a JBL bio80 or JBL bio160.
The Taifun P requires pressure for the carbon dioxide to be pressed through the fine membrane. The pressure formed in the reaction flask of JBL bio80 and JBL bio160 is enough to operate the diffuser.
If there are no fine bubbles coming out of the Taifun P, this may be due to the following:
1) The fermentation of the microorganisms isn’t working (see Solutions in the FAQ for the JBL bioRefill).
2) There might be a leak somewhere in the system where pressure can escape. Potential causes of the leak:
2a) The lid of the reaction vessel isn't screwed onto the cylinder properly. Solution: Clean or perhaps replace the sealing ring in the lid.
2b) The connections of the JBL T3 CO₂ hose where it is connected to the cylinder and the JBL SafeStop aren’t fastened tightly. Solution: The hoses must be pushed onto the connections all the way. If used frequently, we recommend shortening the hose by approx. 1 cm.
Does the use of bubble stones and a strong current expel the important plant nutrient, CO2, from the water?
A bubble stone does NOT expel CO2 from the water. This is a widespread misconception in the hobby! CO2 and O2 are not related to each other in the water. Depending on the degree of saturation and the partial pressure gradient, they dissolve into air. Please bear in mind that we do not add pure oxygen to the aquarium, and instead add an air mixture of nitrogen, CO2, O2 and other components. When air pumps are used for ventilation, there is only an expulsion effect as a result of the enlarged surface of air/water if CO2 is added, to the effect that the partial pressure in the water is higher than in the air. This cannot be quantified without expending significant time and effort on metrology.
