actually ala q ani since my pond built in xa sa house and ala p sad construct and the most important permanent location sa aqng dream pond.... but hopefully someday i could implement pond skimmer bottom drains systems built in filtration system etc... currently i am using 2 way air pump separated air stones connected to the barrel filter and the other below where the outflow of water hits....
but if you want to have DIY... this are procedures for Do It Yourself:
use used materials or recycle materials as possible, the less money and more to save is the BEST for DIY's
make sure you have a powerful air pumps at least 4 chambers air outflow
used pvc piping systems (mas better matago below the ground the better)
have at least 4pcs of air stones (either of any shape but not more than 4 inches)
use bowl set as plate at bottoms in inverted position... if possible on one location lng edges aqng recommend.... or either plastic pots (either unsa imong desire shapes- and or clay pots- w/c has more electrolytes increase water quality)
refer to links for more insights
i also suggest sa imong new pond. pond skimmer.... see links as well
ONE THING TO REMEMBER ALWAYS FOR DIYS = ALWAYS INNOVATE IDEAS...ala'y mawala if try nato create / innovate / improve ideas in our own and REMEMBER: basta Pinoy BAGSIK ana nga FIELD. hehe
