I noticed these in a marine aquaria mag today... $75 metal halide retrofits... . Any opinions? Id go with the upgraded 12K bulbs, 2 175W for my 75. Email me for the link, jasenhicks@hotmail.com
there are many retro fit kits out there from ICE CAP to CORALIFE. It saves on costs and also if you are building your own hood it is the way to go. I just picked up 2 used 175W ICE CAP MH for $230 CND with reflector and a few bulds. I think retro fit kits are the best way to go so that you can mix and match what you want for a lighting system.
email where you can get the retro kit for that price. I am in the market and that is the best price. Please and thank you. tim_russell33 AT yahoo DOT com
Reason I do that is that i've had problems in the past w/ spam mail from "bots" just looking for email addresses.
