If you want to keep sps
, you will need at the MINIMUM 2 175W MH
. You may be able to get enough with PC
but you'll have to stuff your (new custom made) hood with them. You sould not attempt to keep any corals other than very low light types like mushrooms and zooanthids with the lighting you have, even if you double it.
I don't want to discourage you, I want you to succeed. Spend the big $$ and get MH
, you won't regret it.
By the way, I retrofit my DIY
hood with 2 175W MH
for around $200 a few years ago. I can be done cheap if you're handy.
