Airstones will not help at all.. you will pick up 10x more O2 with the water dripping over the rocks (all surface water)its somthing like 90+ % of O2 is picked up in the surface layer.. I run pump 24/7 just for this reason.. if you want more O2 just add a bigger pump this will increase the flow over the hydroton and increase O2.. airstons add O2 cause the bubbles agitate the surface layer the bubbles in the water itself dose not do hardly anything... Except for somthing like a Krusty bucket witch is practically using a shopvac blowing in a Resivor to make a foamy broth.. somthing no fishtank pump could ever come close to doing even a 500gal fish tank pump could not do it... Ill check out your links later
Sounds like a nice batch to me
