Lighting Minimum

[kwirky]

Back when I had T5 HO teklights they bleached my first SPS I ever got

I'm going to be seeing if 150W 14k aquatinic lighting with PC actinics will be enough for SPS on my little 24g tank. It's only 16" deep and running zeovit too *crosses fingers*. I think water clarity has a part in it too. With my softies and LPS (again in my previous tank) I started running active carbon and the water all of a sudden cleared. I had a few colonies bleach on me.

I've been reading all of advanced aquarist's articles on coral colouration too and I think from looking at the articles as a whole it's the symbiotic algae that needs the light. If you can supply sustenence to your coral through other means then the coral can thrive in a lower light environment. For instance if you have mature rock providing lots of microfauna or even the bio supplementation products that could be magic or could be snake oil

I think the actual studies on lighting and colouration in corals being done by advanced aquarist are quite exciting but I'm a geek that way :X
