Buy an air pump on Amazon (paid link): • https://amzn.to/3xowvwN • Music in this video: Ponies and Balloons by The Green Orbs; • How About It by Topher Mohr and Alex Elena. • 00:00 Title • 00:05 We can use a tube built in at the bottom of the aquarium for cleaning the aquarium, adding water and air (oxygen) to the water. • I showed it in previous videos in detail, but here is an example where I use a DIY inline straight air tube connector. • Pumping air through the water has many benefits. • But it creates chaos in a small aquarium. • We can avoid the chaos by reducing air pressure or by enclosing air bubbles in a tube! • 00:44 Let's build a telescopic tube. • I use 2 plastic straws of different sizes (ask for them at a local Starbucks ) with a 6 and 7 mm diameter. • The thin straw slides freely inside the thick straw. • 5 mm diameter air tube fits freely inside of both straws. • Wrap a couple layers of cotton sewing thread around the thin straw, making about 1 cm wide ring closer to one end of the straw. • The thin straw should fit firmly inside of the thick straw. • Cut off the rest of the thread. • This telescopic tube is long enough to fit in my plastic bottle aquariums. • We can adjust the length of the tube. • Put the wide end of the telescopic tube on the protruding end of the air tube at the bottom of the aquarium. • Make sure the air tube is not blocked by a rock or any other object. • 02:12 Turn the air pump on. • Adjust the air pressure to low. • It creates air pockets inside of the telescopic tube. • Water trapped above an air pocket moves up as the air pushes it to the top end of the telescopic tube. • It creates a suction effect at the bottom of the telescopic tube. • 02:37 Regulate the water flow by adjusting the air pressure. • It pumps water above the planter on the top of the aquarium and then water drops back into aquarium. • I am going to use a planter with 3 funnels in this example. • 03:04 Take a small plastic bottle with a cap. • Cut off the top of the plastic bottle. • Trim off the edges. • Cut off the bottom part of the plastic bottle. • Trim off the edges. • Cut out a strip from the edge to the center of the bottom part. • The bottom part should fit inside of the top part of the bottle. • I made the cut wide enough for the air tube to pass through it - I will explain this part in the next video ;) Make a hole in the cap using a hot soldering iron. • The telescopic tube should go freely through the hole in the cap. • The narrow straw goes in the bottle. • Use a needle, a nail, or a hot iron to make little holes about 1-2 cm above the cap. • Holes prevent water overflow. • Loop a rubber band on the narrow straw to make a stopper. • The stopper prevents the bottle from sliding down. • I use padding polyester to filter fish poop. • Wrap a strip of filtering fabric around the straw. • Push the roll in the cap. • Move the rubber band stopper to adjust the height - the straw should protrude above the roll. • Insert the straw in a funnel and put one end of the air tube in the aquarium. • Adjust the height of the telescopic tube. • The cap should be inside of the funnel for the water to drop in the funnel. • Turn on the air pump. • Place the bottom part of the bottle on top as a type of lid. • It is possible to use many commercial filters instead of padding polyester to remove unwanted chemicals • 05:53bRinse the filtering fabric under running water once a day. • And then you can use it again. • I use this slow flow cycle filtering system on rare occasions, mostly to increase oxygen level. • It works for guppies. • It could be useful for other fish. • Have fun and happy fish :) • Blog: http://rndmbits.blogspot.com/2017/01/... • More fun on my website www.fewdoit.com
