Yes same as above!
Not sure who told you leds would not support clams.
Cheap leds will not support anything but troublesome algie! "I used these first they suck"
Radions kick *** on anything!
Sorry pics but under a single radion 14 in from top of tank and 10 more to the clams on the bottom! They hit 51% max power output for about an hour. From ramp up to down!
