what types of corals can be kept in low light conditions?because at the moment i have flourecent lighting. on the internet it says that some corals can be kept in low lighting. like sponges, gorganians, and some soft corals.
You can do a few things that are cool. things that need alittle more place higher in the tank, mushrooms, sponges and some other corals , do alittle reading before buying, and save up for more lighting
That is real low Light, I would try to get some more ligthing and better type of bulbs. PC's are nice and You may be able to pick some up at a good price out of the paper, But even then You want to get new bulbs, most the time people never change them out and when you buy the lights they are over a year old.
I would definitely look into getting better lighting. When they say low lighting, I think of 3 watts per gallon. The PC lighting is good for that. Although, I am a believer that PC lighting can do a lot more if you have the right amount.
Just checking. 15 watts is the highest I have found in the 18 in. My 20 gallon fowler uses that bulb. I agree you might want to upgrade eventually. Mushrooms will definately work but they spread like wildfire!
