Recommended spread is 30x24 on these so it would probably work
Yeah, after a little more research, I’m not sure. The Radion G4 pros are 190 watt and the Orphek compacts are 130 watt. Plus you have to buy the gateway with the orpheks. So the price is about the same. They both say the recommended spread is sufficient but the orpheks have a little more spread.
The Radions seem to be the more proven technology. Could I get away with three G4 pros? If I did four, the layout above my tank would be odd given the two cross braces.
