Cheap Aquarium CO2 Setup

When I first thought about adding CO2 to my planted aquarium, it was difficult to find a list of hardware needed to get things up and running.

This list is a fairly inexpensive way to get started with Co2 in your aquarium.

Hardware used for my first CO2 rig for my 75 gallon freshwater aquarium:

The biggest problem with this setup is that the bubble counter attached to the regulator dries out quickly. Not a huge deal as the diffuser can also be used to track bubbles.

Other than that, this setup has been running well for me for over a year.

That’s the list! I am not a CO2 expert, but will do my best to answer questions that you might have 🙂

Edit: After about a year of this setup, I’ve simplified it a bit, by removing the powerhead and placing the diffuser under the intake of my Fluval FX6 Canister Filter.

It’s one less thing to plug in and the drop-checker still looks the correct color.

I’ve lost track of how many ways I have turned my audio files into sound waves via Logitech Media Server.

Here’s a few:

But, this is an audio streaming hardware setup for Logitech Media Server that I am finally happy with.

(Some Common LMS Commands)

The only confusing part of this setup was incorporating the subwoofer with the HiFiBerry Amp2.

If the subwoofer amplifier has high level inputs (and the Polk sub listed below has these), then daisy chain them together with your speakers like this:

HiFi Berry Amp2 > Sub > Speakers

The Hardware:

This can definitely be improved on.

The Polk sub is just ok, but definitely worth it when it goes on sale. It lists at about $130 USD, but drops to $99 and below on a regular basis.

The Micca speakers are great for the price, but they have a newer more expensive version (Micca RB42) that looks like a worthy successor.

That’s the setup. Let me know if you have something better as I’m always looking to make changes!

Common Logitech Media Server (LMS) Commands

I’ve tried multiple self-hosted audio streaming options including: Ampache, Airsonic, Mopidy, Volumio and more.

However, I always come back to Logitech Media Server.
In my opinion, it’s the best for streaming your audio to your desk (It’s not so great for taking your tunes with you.)

I’m always tinkering or trying out new Logitech Media Server installs, and this is an accumulated Cheat Sheet of Linux/Raspberry Pi commands that I’ve used over the years.

Start, Stop, and Restart LMS

  • sudo service logitechmediaserver start
  • sudo service logitechmediaserver stop
  • sudo service logitechmediaserver restart

Get proper ownership of the main LMS directory

  • sudo chown squeezeboxserver -R /var/lib/squeezeboxserver/

Backup your LMS files

  • sudo cp -r /var/lib/squeezeboxserver MyBackupDirectory

Restore your LMS files

  • sudo service logitechmediaserver stop
  • cd MyBackupDirectory
  • sudo cp -r squeezeboxserver /var/lib/
  • sudo chown squeezeboxserver -R /var/lib/squeezeboxserver/
  • sudo service logitechmediaserver start

Need to copy your favorites back over and the “OPML Playlist Browser & Editor” isn’t cooperating?

CD to the folder where your backup is and use these commands

  • sudo service logitechmediaserver stop
  • sudo cp favorites.opml /var/lib/squeezeboxserver/prefs
  • sudo chown squeezeboxserver /var/lib/squeezeboxserver/prefs/favorites.opml
  • sudo service logitechmediaserver start

Restore just your plugins

  • sudo service logitechmediaserver stop
  • cd MyBackupDirectory/squeezeboxserver/cache/Installed Plugins
  • sudo cp -r Plugins /var/lib/squeezeboxserver/cache/InstalledPlugins/
  • sudo chown squeezeboxserver -R /var/lib/squeezeboxserver/
  • sudo service logitechmediaserver start

Installed a plugin and LMS won’t start?

  • sudo service logitechmediaserver stop
  • cd /var/lib/squeezeboxserver/cache/InstalledPlugins/Plugins
    sudo rm -r MyBadPlugin
  • sudo service logitechmediaserver start

Want to start over without reinstalling?

  • sudo service logitechmediaserver stop
  • cd /var/lib/squeezeboxserver/cache
  • sudo rm *.db
    • If you’d like to verify that you are deleting the correct db first, try this: echo sudo rm *.db which shows which db will be deleted or sudo rm -i *.db which will prompt you to delete the db before it happens.
  • sudo service logitechmediaserver start

Delete everything

  • sudo rm -r /var/lib/squeezeboxserver
  • sudo rm -r /etc/squeezeboxserver
