ive had RBTA for 2 years now and had it split a few times. ive done well with SPS as my tank is mainly SPS. parameters are stable and have tons of flow. have 2 radion pro's (G2) and a 250w MH over a 150gal tank. ive done some research on the Ritteri but could always use more. i ment get my feet wet with a ritteri, not with anemones
