My Lighting Spectrum??

[ScubaSteve]

I keep a 20G with the 150W Coralife Aquapro, HOB filter with carbon, no skimmer. I do water changes every week to two weeks. I'll do it more frequenty is something looks unhappy. I find my colt and frogspawn to be like 'canaries in the coal mine' to let me know it something isn't right. I have eerything in that tank... softies, LPS and SPS. I have a HUGE toadstool in the tank which is a bit of a polluter that upsets the others from times to time but typically I find with carbon this goes away. Oh, and I keep my candy cane right on the sand and he grows like stupid.

Definitely get some test kits. You might it could be something as simple as your pH being off. Test, then dose IF you need it.

Does anyone have success with corals without dosing in a similar setup with a good light, good skimmer and frequent water changes?
