This makes me afraid to check the dkh of the oceans :razz:

i call carbon!!:mrgreen:

See carbon is a very integral part of everything!

1.Back home, people who cannot afford toothpaste used carbon to clean their teeth and it ACTUALLY makes teeth shiny. :razz:
2. Nothing beats the taste of bbq done done with charcoal cooker
3. We get electricity from coal
5. Activated carbon sounds SO COOOOL :mrgreen:

(Ops, looks like carbon washed away number 4 :P)


I guess carbon do like making stuffs shine and taste good (yah I did taste tank water some times to see whether its TOO SALTY) :mrgreen:

I am not opposed to keeping high alkalinity. If my tank was naturally on the high side I would not care if I did not have any RTN.

I have to dose to keep mine even at 7.5, so I try to keep it at 8. It's not has hard to keep the alkalinity stable at 8 than it is at 10 or 12.

I was always told by the pros around here to keep it lower and no need to keep it high as it is not natural and can cause more problem than good.

I also know a few people having problem with RTN when their alkalinity peak too high. Strange coincidence maybe.

More and more people keep their SPS tank at low nutrient level and high alkalinity and run into trouble. Zeovit recommand natural sea water level...their must be a good reason.
