Which radion? I can't decide if I wanna leave as is, get the hydra upgrade kit, or a 350 kessil. Before the hydra kit I was thinking about adding a 12"x1" heat sink with some uv and other colors. How high was your sol suspended?
i went with radion pro. no complain. if i have another chance i would try a kessil 360 but the radion fits all my need.
if i remember correctly it was hung 7in or so above water line. it gave good growth to sps. i was thinking adding a uv and stuff. but it will be really ulgy to look at unless u have a canopy. so i think you should either leave it as is, or get a hydra kit. diy on a rimless with out canopy can be an eyesore. imo
