Yes, I run them on 2 systems in my basement. The scrubber pulls them up from a night time low of 7.5 to 7.7. With the scrubber and a fan in a open window(weather permitting) and a fresh air line on my skimmers I bottom out at about 8.1.
I buy my media in a 5 gallon jug from a vet supply site and it runs me about $100 per year for the 2 of them.
