Who does not know it. Are pumps, skimmers, and various technology once suspended for a while the salt water in our aquariums form calcareous algae and lime scale in it. If you want to remove them now, you can't use the usual "home remedies" or lime solve hydrochloric because they are toxic to our animals. However, there are two exceptions. One is to use citric acid, hydrochloric acid are the other technical lime solution. Both are available in pharmacies in Germany and partly in drug stores, for "little" money. In other countries, other sources will be. This is something that everyone can find easily anywhere in the world. |

How do I use the two acids? Next to the "light" cavalry, the citric acid. Here you can follow the package specification to fix a cleaning solution. Citric acid is, among other things used for the decalcification of coffee makers and espresso machines. It is in contrast to hydrochloric almost biodegradable residue of nature. The important thing is that you do not too much, better leaves no residue on the cleaned things. Better a little longer, rinse, until really the last remnant is gone. PURE Citric acid is very toxic to animals, this has been ascertained to rats (ca.3g / 1kg liveweight). But since we are working with highly diluted acids, we can neglect. Now I don't want to start a chemistry digression but still indicating that citric acid is needed by every living being which breathes oxygen, even only in trace amounts present |

Hydrochloric acid is usually given in 30% -33% sodium diluted form in pharmacies, for our purposes it must again be diluted to about 3%. Most appropriate is to use distilled water or even RO water. |

Warning: Hydrochloric acid can cause burns and irritate the respiratory system! Hydrochloric acid should in principle be kept under wraps and out of the reach of children. In case of burns immediately rinse thoroughly with clean water and then you should go in any case to the doctor. Citric acid at least can cause irritation. With irritation is to proceed as described above. |

The images shown below are valid for the whole of Europe, I am not sure whether for the rest of the world? |

It is important to note that we ALWAYS dilute the acid in the water and NEVER in a different order. Water poured into the acid can lead to an explosive reaction, in which one can incur severe burns. |

As a cleaning vessel, one uses preferably a plastic or glass container. Just in case the device that is to be cleaned has metal parts, you should remove them if possible (applies only for the use of hydrochloric acid). Leaves the parts about 10 to 20 minutes in dilute hydrochloric acid, then take them ( at best with the help of a plastic forceps) from the container and rinse them thoroughly under running water. The procedure of cleaning applies equally to the cleaning with citric acid. |

Critical points for salinization or calcification are for example air- nozzles of venturi pumps and skimmers as wells as veturi nozzle of skimmers. I clean them regularly all 2 - 3 weeks first with likewarm water to keep the efficiency of the skimmer. Helps flush any longer, I use citric acid and only in cases of hardship, hydrochloric acid.the pump or skimmer need to be removed from the sump (TB). Also the air hoses and valves, especially if you also uses an ozonizer, need too regularly to rinsed with warm RO water to avoid failure of the skimmer . |
