In this video we construct the cheapest and most effective form of filtration an undergravel filter, definitely an old school filter but non the less super effective. Enjoy!

Components:
2x plastic seedling trays
1x 12inch piece of 19mm black poly pipe
1x suction cup
1x 1m stretch of 3-4mm airline tubing
1x small air stone
1x air pump
1x 2ft fish tank
1x bucket of gravel

All in all for someone who has a lot of fish equipment this build should not cost any more than $10-$15 max or in my case $0 as I already had everything needed.
