Let’s start with the most frequently asked question: My pump doesn’t start.
Might foreign bodies have entered the pump head?
Might the impeller (or the bearing in the motor block) have been fitted incorrectly?
Is the bearing attached solidly to the shaft and has it hardened?
Is the bearing bush worn out?
Does the motor block or pump head have grinding marks?
Has the pump run dry?
Is electric power available for pump?
There is always a reason for a Red Dragon® pump not starting. In most cases, there will be scaling, a blockage or contamination. The electronics of the Red Dragon® pump stops when the power consumption (current drawn) is too high. If these causes can be eliminated and as long as there are no visual defects, please send the pump to the Royal Exclusiv® customer service. We explicitly point out that is prohibited to circumvent the electronics in the pump by constantly plugging in/unplugging the power plug to make the pump run again. If the Red Dragon® pump switches off, there is a problem which must be remedied. Alternatively, the fuse in the pump could get triggered = complete damage to the motor.

2. Water chemistry, strongly contaminated water and water flow
3. Noises and/or noise reduction

3. Decoupler set usage
My skimmer overflows when it foams, or does not foam at all.
Setting the skimmer:
With a new skimmer, it is completely normal for it to boil over (over flow). Especially at the beginning, the nozzle can be shut completely till it has settled down. Then, after about 2-3 days, the reference position can be taken (for RD3, there is no regulable nozzle, so that in this case, the pump should run at maximum setting for about 2-3 days and then its speed should be drawn down, so that the desired skimmer performance is reached.)
Water chemistry, excessively contaminated water and water flow:
The question of “why does my skimmer not skim” is actually a very complex theme that can also hardly ever be answered satisfactorily. All we can do is carry out the following actions: ...if the pump is running, and the tube is full of air bubbles, then the device is fine from a technical standpoint. There are actually only a few reasons why a Bubble King® does not foam :
a) The skimmer needs urgent cleaning, especially the nozzle and/or the pin wheel
b) And/or chemical reasons, which means that something is preventing or hampering the foam formation. There are many different variants here. An insignificant filter flow can also be responsible, or too little seafood/dirt or a wrongly placed skimmer (this cannot happen with a Dreambox).
c) Do you use a phosphate absorber?
Increased nitrate and phosphate values are always an indication of insufficient skimming (or of the necessity for a water change). Often, the output of a skimmer can be improved by increasing the flow to the filter. This could be the case, but need not necessarily be so.
Ia) The air exhaust: Is the tube not perfectly filled with a white fluid, does it look almost as if one could look through it? In this case, it may be that too little air is being suctioned. This is quite easy to test - just pull off the RSAB-tube(air-hose) to the sound muffler(resonator) and check if things improve. If yes, this means that the sound muffler is blocked (salt crystals, foam material wet?) Please also check that the air suction pipe is completely clear. If any tinkering has been done on the air suction tube, this often has serious effects on a Bubble King. The cause could also be the nozzle, which can be pulled out without removing the skimmer or the pump from the filter. Here, the red 10 mm nipple in particular must be checked for scaling.
My delivery pump does not run, or gets switched off after 3-5 start attempts?
Not this way, please! Incorrect piping:
Clearly wrongly piped pumps, with angles right at the intake fitting. All our pumps are not self-priming.
Not like this, please! Scaled and dirty pumps.
Badly scaled pumps and impellers. This pump came to a standstill because of the scaling.
Not this way, please! Scaled and dirty pumps.
Very badly fouled pump - not a problem from the outside; if the pump looks like this on the outside, it cannot look much better inside. Regular maintenance and cleaning of your pump extends its service life!
After expert cleaning, even this pump started without any problems.
Auch diese Pumpe lief nach einer fachgerechten Reinigung problemlos wieder an. Bitte für eine aussreichende Vorfilterung Ihres Wassers im Technikbecken/Filtersumpf sorgen.
This is what the pump looked like after expert cleaning.
Please de-couple the pumps to avoid transfer of the vibrations to or from the piping system.
Pumps de-coupled on the intake and pressure sides with silicon hose and V4A (acid-resistant and hardened) hose clips.
