Dennis, typically CanadianPond type Bubble tubing takes .045 cfm per ft of tubing. A typical 1/2 hp compressor with 4.5 cfm can supply air to 100 ft of BT.Your system if it is a HF Brookwood has open flow of 5.6 cfm . You would have to know how much of that is specified to your needed lifting rate from your 3 Vertex stations to see if you had any to spare.If you take too much from the stations to satisfy the BT it may be counter productive.Hope this helps.
