Yep media bag is good enough in the short term just put in good flow and shake it daily, other than that yes a reactor will do but remember the media needs shaking daily this is why there are dedicated reactors for Lith.
We have one coming to the market in June that will be a competitor for Vertex brand we are just finalising some of the neat features it will have over other brands, prices are expected to be cheaper also depending on what the USD rate does between now and then. If we decide to blow the market open on these and sell direct then they will be 50% cheaper
