astroboy December 10, 2008 Share December 10, 2008 Greetings coral comrades! I have a 75 gallon tank, 360W compact fluorescents, of which 120W are 10K, the remainder are actinic03. I have some bare spots in the live rock, 8-10 inches below the bulbs, which are just begging me to put acroporas there. Does anyone have any insights as to whether the lighting is sufficient for acros, or are they most likely just to brown out and not grow? Thanks!

Thanks! more than likely they will wither away, I have seen one person do it but it was on a pico 2.5 gallons that was attached to his main tank water supply and blasted it with 65watt PC's... it worked but in the end he broke it down because the SPS lost color. why don't you upgrade to t5's and grow a ton of SPS? IceCap ballast retro t5 kit 4-6 bulbs should do it real nice. IMHO cheers! Link to comment Share on other sites More sharing options...
ctenophore December 10, 2008 Share December 10, 2008 You might be okay with some of the lower light acros, aka the "deepwater" varieties. A. caroliniana, A. jacquelinae, etc. More important than light intensity IMO is water flow and water quality. PO4 should be nearly undetectable, NO3 5-10ppm or lower. If you use carbon, you will probably get better light penetration, hence more punch from the PC bulbs. Same goes for any other water clarifying device, such as micron filter socks, ozone, UV, etc. I think you should give it a try assuming the other requirements are met. Nearly every photosynthetic coral is capable of adapting to widely varying light levels. Link to comment Share on other sites More sharing options...
zygote2k December 10, 2008 Share December 10, 2008 There have been several successful SPS tanks lit by Power Compacts. Same thing with VHO's. With the current hype about T-5's, people have just forgotten. Link to comment Share on other sites More sharing options...

Depending on the depth of the tank it might be worth stepping up to 200w Link to comment Share on other sites More sharing options...
