This came out of a Fluval Flora kit. I bought the kit thinking I was going to setup a FW planted tank but decided against it and have done a small mini reef instead. Pick up can be arranged for Downtown Calgary or Harvest Hills area.
Fluval Strata - $10
Fluval Flourite Black -$20
Fluval Mini Pressurized 20 g CO2 Kit for FW planted tank -$30
40$ for the lot
