it is near impossible to try and keep a healthy reef tank with ANY stoney corals whatsoever without maintaining levels. Basically to short answer your question NO you cannot just dabble with sps or lps without keeping your levels up, now you can do that by Either dosing or water changes (depending on your salt) He uses red sea which is PACKED with trace elements. so if you wanna be technical YES he still very much so doses, just not with pure elements but with his quality salt mix
