JBL AquaCristal UV-C: Can I leave the UV-C water clarifier running while using remedies?
Always switch off the UV-C water clarifier while using remedies.
JBL AquaCristal UV-C: Does a UV-C water clarifier heat up my tank water?
It is relatively unlikely that a UV-C water clarifier will heat up tank water, at least to the extent you have indicated. The so-called delta temperature, that is the difference in temperature between the temperature setting and the temperature actually reached, as well as the room temperature, would be important for an assessment.
JBL AquaCristal UV-C: How long should the burner be on every day ?
It's not possible to make a general statement as to how long the burner should be on every day from a distance, as this requires information such as the germ count and the germ growth rate of the aquarium. However, basing on experience, I would not keep the 36 W burner on for less than 12 h daily. In terms of the service life of the burner, non-stop operation would be preferable.
JBL AquaCristal UV-C: You can see violet-blue light on the sides. Is that harmful for me?
The light coming out of the connectors and shimmering lightly through the casing is not harmful for humans and no longer contains any UV-C radiation.
JBL AquaCristal UV-C: When is non-stop operation of the burner advisable?
Particularly if you are experiencing trouble with bacterial infections of the animals, non-stop operation of the UV-C water clarifier is advisable. This is the only way to achieve effective reduction of the density of microbes in the water. If no diseases are present, operation can be limited to 12 h per day.
JBL AquaCristal UV-C: Can I store my water tests near the UV-C appliance?
Water tests can be stored near a UV-C water clarifier with no trouble, as the bluish light that "shines out of" the hose connector is harmless. Besides this, the liquid reagents are contained in dark plastic bottles.
JBL AquaCristal UV-C: Does the ultraviolet light destroy active ingredients of my aquatic plant fertiliser?
UV-C breaks down the chelates in the fertilisers, which prevent the precipitation of trace elements such as iron, among many others. Therefore, when using a UV-C water clarifier, it is advisable to change over to daily fertilisation and convert the standard dose into a daily application at the beginning. It may also be necessary to increase the fertiliser dose slightly. Traces of iron should at least be detectable prior to the respective next application of fertiliser. Vitamins and other higher grade organic compounds may likewise be broken down. Therefore, when using vitamins, it is advisable to add the fertiliser with the food twice a week.
JBL AquaCristal UV-C: There are sure to be some of them floating around now, and I would like to know whether they will be killed by a UV-C water clarifier.
A UV-C lamp kills all of the organisms floating around in the water, to the effect that the cyanobacteria will be killed as well.
JBL AquaCristal UV-C: What do you mean by flow rate, and should I reduce the filter output?
Flow rate refers to the actual rate of flow through the UV-C water clarifier. If the UV-C water clarifier is connected behind the filter, all of the water cleaned by the filter flows through the clarifier and the sterilising effect lasts much longer (relative to the total amount of water in the tank). When using a filter with a high output, it is recommended to either use separate installation by means of a small circulation pump or operation in a bypass, i.e. from the filter outlet into a Y-piece, next, to install the clarifier in one of the circuits and then to connect the two hoses again by using a second y-piece, and then to lead back into the tank.
How much electric power (Watts) does my AquaCristal UV-C water clarifier need for a partial sterilization?
In the instruction booklet for the JBL AquaCristal we recommend the 18 W UV-C water clarifier for a partial sterilization of aquariums of up to 400 l max. and with a flow rate of up to 200 l/h. For a more extensive germ elimination the use of the bigger 36 W clarifier is advisable. Here the recommended flow rate of about up to 400 l/h needs to be taken into account. This makes a bypass connection advisable for most of the usual external filters in such aquariums.
Size of JBL AquaCristal UV-C 5 W ?
The data refer to the installed appliance without control gear:
Length incl. of cable gland: 22 cm
Housing diameter, measured where lamp holder screws onto UVC steriliser body: 8.5 cm
Diameter with hose-tails and mount: 16 cm
After two weeks, there is still slight whitish cloudiness in the tank. Therefore, I would like to purchase a UV-C clarifier. What flow rate do I need to get ?
Please check the table in the instructions for use which can be downloaded at http://www.jbl.de/de/aquaristik-suesswasser-produkte/detail/2387/jbl-aquacristal-uv-c-5w#download.
In the graphic depiction in the instructions for use for JBL AquaCristal UV-C, the UV-C water clarifier is connected behind the filter in an aquarium, whereas it is connected before the filter unit in a pond. Why is that so?
A UV-C water clarifier is generally always connected after the pump in order to ensure proper flow.
In the majority of pond filters (with the exception of pressure filters), the filter holder is higher than the pond water level, the water flows out of the filter and back into the pond by gravity. The pond pump is in the pond. Therefore, it must be installed between the pump and the filter unit to prevent the water from backing up in the UV-C water clarifier.
I have green water in my aquarium, and even water changes and changing the filter media only helps for a short time.
Green water means floating algae, which in turn grow due to a lack of competition with other plants and, especially, due to excessively strong nutrient pollution of the water on account of the excrements of the fish. The filter will not be able to do much about this. Ultimately, there are only two possibilities.
1. Carry out significantly more water changes in order to remove the nutrients from the excrements of the fish.
2. A JBL AquaCristal UV-C water clarifier kills off the floating algae.
The light can be turned off for 2-3 days in order to stop the photosynthesis of the algae.
Do I have to turn off the UV clarifier when I add JBL Denitrol to my aquarium?
Yes, that would be advisable. It takes some time for the bacteria to settle on the substrate and, until then, they float freely in the water, so that the UV-C rays would kill them off. Therefore, it is recommended to turn it off for 1 day this day.
