Up for sale is a great little co2 setup for those nano planted tanks. I even had it running on my 20g long with great success. Included is a 24oz paintball co2 tank that is still 75% full and matching mini regulator w/ solenoid from Aquatek. Product listed here for all specifications CO2 REGULATOR SOLENOID. Time for me to pass this on to someone who will make good use of it as I have no planted tanks currently. I am looking to get $100 for both. Pickup in Abbotsford. I will also throw in a diffuser or two if I can find any in my supplies bin. Thanks for looking.
