ok I know it's not the most vital piece of equipment
but it seems to make the hobby allot simpler and help
corals to really grow.. I went to a local store today
that was supposed to have knowledge about the units I
left disappointed. they only carry two models the
Coralife and Deltec the Coralife is cheep in my
opinion and the Deltec was 500 bucks I only have a 130
gallon tank,just for the unit. been doing allot of
looking and I keep coming back to this unit

at the CR1 or CR2 and I can get a monitor and all for less
then that Deltec.
