How the CO2 Micro-Perler works:
The CO2 supplied by the CO2 fertilizer system is farced through the micropore filter tube, thereby farming thousands of tiny CO2 bubbles that quickly and effectively dissolve in the steady flow of water. The CO2 enriched water then enters the aquarium through the filter return line.
Other gases that occur naturally in the aquarium water – so-called waste gases - are also carried along. However, these do not dissolve, but farm small bubbles that are automatically expelled by the filter.
The Micro-Perler Special is used in place of the standard filter basket on the intake line of the external filter.
Aquarium size and suitable external filters:
Given normal CO2 requirements, the MicroPerler Special can supply aquariums of up to 400 litres. The device is ideally suited for use with all external filters with a water flow from bottom to top and a minimum water output of approx. 100 litres/hour., i.e. for practically all standard models.
In the case of filters with on output in excess of 400 litres/hour, we recommend connecting two Micra-Perlers Special (see Fig.). External filters with a water flow from top to bottom are not suitable, since it is not possible to expel the waste gases, which in turn impairs the filter function.
The Micro-Perler Special can be used in combination with all standard CO2 supply systems.
Precise control using the CO2 bubble counter Exact:
The number of bubbles per minute is used to calculate the amount of CO2 in the aquarium. The Dennerle CO2 bubble counter Exact caters for simple and convenient readings: since it is swivel-mounted, it can be moved into the ideal position. The white reflector bracket makes it possible to count the bubbles accurately, even in poor lighting conditions, for example, in the floor cupboard. Strong hose connectors with coupling rings provide secure connections and guard against CO2 leaks.
The CO2 bubbles generated by the Dennerle CO2 bubble counter Exact have an average weight of approx. 0.125 mg and a volume of 0.063 ml. 10 bubbles per minute therefore correspond to a CO2 supply of approx 1.8g or 0.9 litres per day.
What is what:
1) CO2 hose connector for 4 7 6 mm hoses;
2) Hose connector for external filters for hoses measuring 12/16 mm and 16/22 mm;
3) Longlife suction cups;
4) Micro-pore filter tube;
5) CO2 compartment;
6) Suction basket;
Prior to installation
To ensure that the Micro-Perler Special can generate especially fine CO2 bubbles, the Micro-pore filter tube has to be soaked in water and allowed to expand. Therefore, place the Micro-Perler in water at least 12 hours prior to installation or install it in the aquarium and wait for 12 hours before activating the CO2 supply.
How to install the Micro-Perler Special correctly:
1. Rinse the Micro-Perler Special with warm tap water. Do not use detergent!
2. Plug the CO2 supply hose onto the hose connector.
Tip: Dipping the end of the hose into hot water briefly beforehand makes it easier to slide it over the hose connector.
3. Select a suitable spot in the aquarium to affix the unit. The spot should not be too bright, to prevent possible algae growth. Disconnect the existing filter basket on the intake hose of the external filter and attach the Micro-Perler. The hose connector is designed to fix standard hose sizes 12/16 mm and 16/22 mm (TIP: when using a 16/22 mm hose, it is possible to cut or saw off the thinner top section of the nipple to increase the water flow). If the external filter is equipped with an intake pipe, connect the Micro-Perler and the intake tube with an appropriate lenght of hose.
4. Secure the Micro-Perler Special as far down in aquarium as possible using the two suction cups.
What is what:
1) Mounting brocket;
2) Fastening clip;
3) Slots for attaching the unit with a strap;
4) Longlife suction cups with suction nipples;
5) Bubble counter;
6) Bubble counter tube;
7) CO2 supply from the pressure reducer (needle valve);
8) CO2 outflow into the aquarium;
9) Reflector Bracket;
How to install the CO2 bubble counter Exact correctly:
1. Open both fastening clips and remove the bubble counter from the mounting brocket.
2. Ideally, the bubble counter should be attached directly to the CO2 cylinder. This means that it is in the immediate vicinity of the pressure reducer.
Advantage: adjustment made to the amount of CO2 supplied by the needle valve of the pressure, are immediately visible on the bubble counter. For this purpose, feed the strap through the two slots in the mounting bracket with the fleecy side facing outwards and attach the mounting bracket to the CO2 cylinder. If desired, remove the LongLife suction cups and suction nipples beforehand.
Further fastening options: (1)using the two suction cups to the side of the aquarium or (2) using screws (not included in the scape of delivery) to the wall or in a floor cupboard. For this purpose, remove the suction cups and suction nipples. If using a CO2 night cut-off valve, the bubble counter should be installed as follows pressure reducer - night cut-off valve - check valve - bubble counter CO2 diffusor (see assembly example).
3. Pour tap water into the bubble counter until it is ¾ full.
Tip: This is done most easily by immersing the bubble counter in water and gently topping it against the hose connectors.
4. Cut the CO2 hose at on appropriate point. Unscrew the connecting nuts on the bubble counter and slip them over the hose ends. Attach the hose coming from the pressure reducer to the hose connector with the bubble counter tube and the hose leading to the aquarium to the other hose connector. Screw the connecting nuts on tightly again.
5. Click the bubble counter in place in the mounting bracket and secure the fastening clips.
6. Align the bubble counter and the reflector brocket by turning so that the CO2 bubbles are clearly visible.
7. Set the required amount of CO2 via the needle valve on the pressure reducer. For this purpose, please also consult the instructions for the other components of your CO2 fertilizer system.
The right amount of CO2:
For magnificent plant growth, Dennerle recommends a CO2 level in the aquarium of between 15 and 30 mg/l; between 20 and 25 mg/l is ideal. The number of bubbles per minute required to achieve this CO2 level depends on a number of factors (types of plants used, water current, surface area/volume ratio, etc.). This is why it is always necessary to determine the CO2 amounts for each aquarium individually.
Rule of thumb for the basic setting: start with approx. 10 bubbles per minute per 100 l of aquarium water: e.g, for a 200-1 aquarium, use 2 x 10= 20 bubbles per minute. Check the CO2 supply and the CO2 levels in the aquarium water regularly and adjust the CO2 supply if necessary. Warning: if necessary, only ever increase the CO2 level gradually over the course of several days!
Please note: the more vigorously the surface of the water is set in motion (e.q. by filters, additional aeration), the more CO2 will be expelled from the aquarium again.
Dennerle Professional tip:
- It is easiest to measure the CO2 content using the Dennerle CO2 long-term test Correct. This test directly and continuously indicates the CO2 content of the aquarium water via corresponding colouring. GREEN corresponds to the optimum value of between 20 and 25 mg/1. No further aids or water testing are necessary to determine CO2 levels!
Cleaning the Micro-Perler Special and the bubble counter Exact:
Clean with warm water and a soft sponge. Do not use any detergents. The filter basket on the Micro•Perler can be removed to facilitate cleaning. Clean the inside of the micro-pore filter tube using a soft bottle brush.
Dennerle Professional tips
- Always protect your valuable pressure reducer against corrosion caused by intake of water! To do so, use only check valves designed for use in combination with CO2 , e.g. the Dennerle CO2 special check valve. Standard air check valves may become brittle through contact with CO2 within only a short space of time, making them leaky. This usually occurs unnoticed.
- Every day, large quantities of valuable CO2 may be lost through hoses that are not CO2 -Proof. That is why we recommend using the Special Dennerle CO2 hose Softflex.
