Coralife Royal blue bulbs

[got2envy]

I have a Coralife fixture that came with 2x65 10000k lights..i was looking for more blue in my tank..if I switch one bulb to a "royal blue" will this be enough light for soft corals? it says it has a 470nm depth..thanks..The guy at big al's said it did not matter as blue light penetrates deeper than white light, is this true?..i want to make sure that I have enough light

so it would be 1xroyalblue and 1x10000k

thanks

well.. what he said is very very misleading. the PAR of a 10000K bulb is greater and will therefore penetrate deeper. 2X65 watts is enough light depending on the size tank. is this on your 125? i wouldnt put any photosynthetic coralsin there if it.

no it's for my 29g..i figured the guy was just trying to sell me a bulb :headshake2: so the 2x 10000k are better than a 470nm blue light and a 10000k light.. how about a 50/50 and a 10000k?

on a 29 you could defiantly keep softies with the blue and the white light. do what you want. the two lower Ks will give you more PAR, but you can get by fine if you are keeping softies with a white and a blue. itll give the corals more color.
