Hi, fish friends! Here is a walkthrough of the two DIY Bog Filters I built for my pond for less than $100.

Bog filters are fantastic at fighting off algal blooms in the water column, especially if they are well planted with bog plants, like the horsetail reed shown here.

This is my first YouTube video so if you enjoyed, I would super duper appreciate it if you hit the subscribe button to be notified of my future uploads.

Q: What is the BEST place to buy aquarium fish, plants and shrimp online?

    Wanted to see more of the results, can't wait for part two
  • I must say, that is a very good idea, especially for a above ground pond.

    If you put a uv light in the filter, or through the pump line and you will never have green water again. I built a bog filter as well to help with filtering etc. Haha I did clay pellets, they float and float into the water. You need pea gravel on top.

    I have had this idea for a while now but with a square and longer planter. Great video Hope you show us your pond in detail that window looks awesome ๐Ÿ˜Ž

    This is a great idea. I think Iโ€™m gonna try it on my pond

    Great idea๐Ÿ˜€๐Ÿ˜€๐Ÿ‘๐Ÿ‘
  • Cover it with shade cloth. I've had a 150 gal stock tank for 4 years now in my backyard with koi and goldfish. Sump tank is in the ground with a old dock float as a dwc bed. Water has always been clear. Next door neighbors tree shades that area til about noon everyday, that definitely helps. Sun is your enemy!

    Good design. Tried something similar and had issues with the pump getting clogged with leaves, grass, etc.
  • Your captions are so funny. Your โ€œmess upsโ€ that you correct via captions remind me very much of myself! Thanks for the video.

    Hiya nat, thanks for sharing this, i just gots all the bits from this video, and am currently setting it up. I will share my findings. Cheers

    finally - a video i understand and love thank you so much lol
  • @RogueAquariums
    A good idea Nat at a budget price!! Subbed your channel.
  • @BrizzleKoi
    Just found your channel...cool pond! Thinking about building a bog filter myself. Liked and subed!
  • I have heard (while researching flytraps,) that clay pellets can add nutrients. Also lava rock has better surface volumes that beneficial bacteria love. I have a pond in Wisconsin USA and it works great even in our harsh winters! This year I'm expanding my bog filter and water volume! Thx for your video.
  • This is awesome! Does the water have to naturally move up just because the filtering medium is rock, or is that true as well for all the DIY videos that use poly batting/sponges/etc? Most of those videos have it coming in via the top and I started building one that way but now I'm wondering if I should start over... I'm such a newbie so I appreciate any advice :)

    What was outcome? Started pond only to have algae bloom immediately. Have since started entirely over cleaning everything out and beginning bog filter directly into pond itself. Day three - so far so good.

    Hey Nat, how did it work for you? The algae grows because it has a food source (look up "nitrogen cycle"). A bog fliter helps as it pulls poop from the tank, but also has plants feeding - which in turns reduces the amount of food for algae. So if the water is still green, try adding more plants and or increasing the size of the bog. There are a ton of good videos out there that provide an in-depth discussion on setup and how it works. If your water has clear, ignore my ramblings :)
