The big pipe is no use here other than keeping the bio media, the media is not relating to the air suction. the air and water suction is happening in the small pipe. you can keep them separately.
The water bubbles are taking the water up as air moves up and this creates suction at the base of the open air tube pipe which pulls water from the top through the gravel media
To build filters using air to pump water is as old as the first fish tank. The system was used for internal filters, external filters and also for "under the sand" filters but they are not used anymore because they are noisy, inefficient and increases a lot the Ph by removing CO² from the water
Oh not true, lots of breeders use under the gravel filters with a hole in the bottom of the tank to siphon the waste out when needed. Actually the simplest system and effective!
nice! i might have to do this with some sponge filters(the type you attach to an air line) i could attach them to the output pipe and as such when it is cleaning time the outer pipe will keep all of the debris in.
Excelente idea, solo que yo le pondría dos piedras aireadoras, una en cada tubo para acelerar más la entrada del agua de la parte baja del tubo y que esta pase por la guata y las bolas y de alli terminar su recorrido al ser expulsada por la boquilla superior.
@Orion X5 Si usa motor amigo lo que pasa es que es externo y la única función que tiene ese motor solo es lanzar aire, es como un mini compresor por eso observa que se le instaló una manguera transparente y al final se le coloco una especie de piedra por la cual salen burbujas y estas hacen que el agua alcance la salida.
good question, since it is an air riser type(no moving parts) and has a relatively low suction. you could probably get away with using some plastic knitting mesh on the inlet to keep the shrimp from being sucked up or trying to make a home in the filter.
Не эффективно чтобы сменить фильтр нужно будет вытащить весь блок , в детстве делал подобное устройство г .р. лифт называется дак фильтр был в отдельной ёмкости на стенке аквариума . В любой момент можно было поменять не вынимая из аквариума.
