I don't know how a seabe would do under your (2) 175 MH and (2) 96 watt PC's. I would only be guessing if I said anything either way - postive or negative.
I will say this.
I keep one under 500 watts of MH and 440 watts of mixed VHO.
But here's the kicker ..
The anemone is located at the far end of the tank, near the bottom of the rockwork. The anemone has not moved from this spot in over 19 months.
It does not receive full intensity lighting from one, let alone both 250 watt MH lamps.
Same goes with the VHO lighting.
The VHO spreads the light out somewhat over the entire length of the 4 foot bulbs.
How much light does the sebae actually receive - I still just don't know yet.
