Dad, I must say... your just wrong... when it comes to saying... T5's not growing corals in RMS tanks & the corals growing long term and prospering - the RSM Club on RS is full of tank threads proving just the opposite.
and there nothing special about RSM tanks & T5's, T5 lights in many tanks have proven to grow corals & provide for them long term.
to me this is a condescending very over general assumption
I think anyone willing to drop $5.500 on a all in one tank. Will prolly end up BUY A NEW CORAL WNEN THIS ONE DIES REEFER ANYHOW
The new S series tanks... with 800 watts of T5 on the RSM 650 will sustainable long term growth of all corals, including the most delicate SPS corals.
Lighting – standard configuration - 10 - 80W - T5 REEF-SPEC fluorescent 5 X 15,000K / 3 X Actinic (22,000K) / 2 X Pink + LED moonlighs
I say this... not to knock LEDs in anyway, or to compare T5's to them, I am sure Leds are very good too & most likely the future, but that does not make T5 obsolete yet, imo
