Best Filters For Discus Fish
Filtration is very crucial and its importance cannot be brushed off in any fish tank or aquarium. The fact of the matter is that the higher the level filtration in the fish tank the better it is for the fish. Discus fish require one of the highest levels filtration because of their messy nature. It is recommended that you always have a level of filtration which is way higher than the size of your fish tank. This clearly means that if your fish tank is say 50 gals, then your need a larger filter of up to 100 gals or even more or chooses to have more than one filter of 50 gals. Here we will discus the best filters for discus fish.
The best filters for discus fish come in a variety of types, namely; under-gravel (UG), hang on the back (HOB), internal and canister. The most preferred Discus fish filters are mainly internal and HOB (hang on back) filters even though canister filters are also preferred for larger fish tanks. The main reason why internal and HOB filters are preferred for Discus fish is because Discus fish are very messy when they eat. This means their rate of making the water in the tank dirty is way higher compared to some other species. The reason attributed to Discus fish messiness is their feeding habits as well as their straight intestinal tract. This means therefore that the filtration system should in this case have a higher rate of filtration than in a normal condition. This is what internal and HOD filters do exactly. The rule of thumb for filtration is 10x per hour per tank turnover. This allows good water movement, but of course is the bare minimum when it comes to Discus fish tank.
Apart from the effectiveness of a filter in doing the filtration, its price is also paramount. When you choose the best filters for discus fish you must compare both efficiency and the price. Also, the noise levels of the filters are considered. Aqua clear which is HOB filter is among one of the very quiet ones. Do not use an under gravel filter in a discus tank. Under gravel filters are intended to trap the waste under the gravel. Eventually the waste will become bacteria and foul your water. Under gravel filters are fine for other fish but not for discus.
Most of the varieties of filters above come complete with filter media which is actually what goes inside the filter. The filter media can be ceramic rings, sponges, pads, etc. however, some of the filters also come with charcoal. The importance of charcoal in the fish tank is debatable and is mainly used to remove medications from the water after treating for an illness but generally but aside from that, charcoal isn’t really necessary in the discus fish tank. This does not mean however that charcoal can be harmful when kept in the fish tank filter but you may choose to replace the carbon (which is the component of charcoal) with another form of filter insert such as a sponge or ceramic rings.
The filter should be cleaned every 6 months. When cleaning your filter only replace the sponge/cotton material and do not rinse out or change any of the other media in the filter. It very important that the beneficial bacteria in your filter is not disturbed. Therefore, it is recommended that you only replace the filter cotton/sponge media when it is critically necessary.
