Dosing for coral growth

[Lampshade]

Carbon has been used for MANY years, however it's still a big unknown. I stay away from it. My own preference, but works for me.

Try running without carbon for a bit even, carbon leaches out many trace elements that we need. Unless you have heavy LPS/SPS combo it shouldn't be an issue. I have 20+ SPS and 15+ LPS in my tank and only run carbon once a week for 24 hours(when i remember :S). I've had excelent growth on all my SPS, even some hidden away from good lighting.


As for the silicone thing, copper attatches itself to anything and everything it can, doesn't take much. They used to make mirror's by evaporating copper onto glass, and it would bond. I could only imagine how much gets onto the glass after dosing :S
