Need advice on pressure setting and SS aeration stone size. Have the oxygen tank and regulator from my gas welding set up. What pressure setting do most of you use with an adjustable regulator. Think increasing the pressure until I see bubbles and backing off a bit will work. A ballpark initial starting pressure setting will help.
Air stone size. Commonly see .5 and 2 micron SS aeration stones. Thinking the .5 would be best as the smaller bubbles should get absorbed quicker.
Is the Williams air wand worth it? Thinking the stone at the end of vinyl tubing may float when oxygen is introduced. The Williams wand gets good reviews, just wondering if the stone and tubing works as well?
Just discovered Morebeer also carries a wand, $29.50 with free shipping. http://morebeer.com/view_product/18255//Diffusion_Stone_-_5_Micron_26%22_long
Beats the William's one for $34.90 plus $7.50 shipping if it is as good. Any thoughts?
