Installation technical items

Aquarium technology

Here’s how to install your technical aquarium items safely and easily

Assuming you don’t want your technical equipment on show in your aquarium, it’s best to cover them with stones, wood and plants, during the setup. It certainly makes a lot of sense to install the technical items in the aquarium FIRST before setting up the rest. Let’s have a look at the technical items:

1. Substrate heating

In general you can only install a substrate heater during the initial setup because it needs to be positioned BELOW the substrate. Attach the suction cups enclosed to the borders of the bottom pane and then install the undergravel heating cable. Always start with the beginning of the “warm cable” because the undergravel heating cable has a certain length of cold, NON-heating lead, which does NOT warm up. This part should run from outside the substrate to the water surface and from there to the transformer. As an alternative you can also permanently and safely attach the heating cable with silicone adhesive dots to the bottom pane ( JBL AquaSil black ).

2. Heater

Automatic heating elements, such as JBL ProTemp S 25 switch themselves off when they reach the water temperature set on the heater top. You can place the JBL heaters anywhere inside the aquarium, even hidden behind the decoration. But around the heater area a certain water circulation should always be available. The pilot light can’t be seen any more when the heater is completely covered. This is not a big problem, but the light does show you when the heater in on.

3. Thermometer

Choose a position where the thermometer can easily be read and isn’t too distracting visually. The position can be freely selected, since the water needs the same temperature everywhere in the aquarium.

4. Internal filter

Internal filters are mostly installed in the rear corners. Here they are discreet and can be slightly covered by plants and decoration elements. Don’t lean elements of decoration against the filter because it needs to be taken out of the aquarium for cleaning.

5. External filter suction pipe/outflow pipe

Suction and outflow pipe of your external filter should BOTH be attached to the left or right side. This creates a water circulation from the outflow pipe to the opposite side and then near the bottom returning back to the suction pipe. It’s good when you can see the strainer through the front pane, so that you can see when it’s clogged by waste, such as leaves.

6. Surface skimmer

For the attachment you have the choice between the left or right rear corner. The surface skimmer has (extends) the same function as your filter suction pipe and should, similary to the suction pipe, be installed in proximity to the outflow pipe of the external filter.

A suitable surface skimmer is the JBL TopClean II .

7. CO2 diffuser

You can freely choose the place where you want the CO2 diffuser ( JBL ProFlora Taifun S5 ) to be positioned in your aquarium. If the CO2 diffuser is not visible, because it has been hidden behind the decoration, you can monitor the CO2 quantity being supplied using an external bubble counter ( JBL ProFlora CO2 Count Safe ). If your CO2 diffuser is shorter than the aquarium height, insert it as deep into the tank as possible so that the water pressure is higher and the diffusion path to the water surface is longer.

8. Inline diffuser for CO2

If you don’t want to have a CO2 diffuser INSIDE the aquarium you can have the CO2 blown into the water by the returning water flow of the external filter. For this purpose the JBL ProFlora Direct has been developed. It can simply be integrated into the outlet filter hose.

9. Air stone

The position of the air stone is up to you. Just take care that the filter can’t draw in air bubbles.

10. Automatic feeder

Please check where your aquarium cover or cover pane offers a possibility for the attachment. You need a hole of about 4 x 4 cm in size where the food can fall onto the water surface.

11. Circulation pumps

You can fix the circulation pump(s) in freshwater aquariums to support the flow of water from the filter outlet. A change in the current direction is not required. For a marine aquarium it is useful to change the flow direction by means of one or two timers, similar to ebb and flow every 6 hours.

12. Cooling

Cooling fans should be fixed on one longitudinal side of your aquarium, so the air flow can cover the longest possible water surface to cause maximum cooling by evaporation.

13. UV-C water clarifier

UV-C water clarifiers are always installed outside the aquarium with a separate water pump (JBL ProFlow u). Ideally, use either a vertical mounting for the air in the water to escape with the water flow to the top – or alternatively a horizontal mounting with the water connections upwards so that the air bubbles in the water can escape to the top here too. It is important to follow the recommended pump output!

14. Lighting

The lighting, whether if fluorescent tube or LED, ought to be installed as close as possible to the water surface. Mostly this is predetermined by the mount. It is important that the lighting can’t accidentally fall into the water. If this should happen, your lamp requires protection class IPX7 against short immersion into water to protect you from an electric shock.
