i use both. i found that when i use oceanic i have to dose trace elements less, and with instant ocean, i have to dose every day. i switch between the 2 all the time, and my tanks are fine.
it makes sense. with the lack of light, they are forced to eat. and with no light at all it will need more polyps to feed it, so it would grow itself more.
i dont have SPS, but i sometimes turn my MH light off. i also play with the timers.
my puppy is a mini doberman and german shepperd mix, if that counts. she is a great and reliable dog. she is 10 months old an is very quit. the only time i have ever heard her bark is at kites at the beach :) they really piss her off. she tags a long, and at the beach i have no problem letting...
i got home today, and there was a negative improvement when he was put to lower flow. he seemed to "melt" down a little, and was a darker brown color in certain spots compared, to a tan-yellow.
can anyone link to an SPS guide? i'm looking to move over to hard corals, but i'm kinda lost. I nkow about trace elements and dosing, lighting, and flow. but is there anything else?
