IF you had the time to read this thread in full, and the previous thread you would have seen that the good people here had already come to that conclusion and in fact the removal of the CC has already in part begun
I had seen where some had suggested to remove it and others said don't remove it. *I was replying to Dave's question ;
So with his current test readings why is the Calcium and alk still high and have been for so long? Which is it? *
What do you mean which is it ? Read it again
Lets try it again same thing

Some is saying air in a power head is a bad idea, that is not so. The aeration will increase the
O2 and drive off the
CO2, a good thing. Driving
off *(decrease) the CO2 will increase the pH, a good thing. Aeration will drive
in (increase)
O2, a good thing.
CO2 and
O2 have nothing to do with one another. Your pH will tell you nothing about what the
O2 level is. Your
O2 level will tell you nothing about your pH level. If for the sake of argument the pH was 8.3 and I added pure
O2 , it will not change the pH...period. If I added pure
CO2 *to lower the pH it will not change the
O2 *level....period

| That was the reason I asked you to aerate some water over night and then test the PH. *If I am correct then the water ( now fully saturated with Oxygen ) should have a lower PH O2 has nothing to do with pH at all, be it night or day. The pH will be higher not lower, as you will drive of the CO2 *

1. Aerating the water does not mean it is fully saturated with
O2
2. Even if the water was fully saturated with
O2, it has NOTHING to do with pH.
3. Aerating the water will not lower the pH but increase the the pH. *Driving off
CO2 increases pH, it does not decrease pH
4. Plants use up
O2 during the night, which lowers the
O2. *During the day they give off
O2, which raises the
O2
5. Plants give off
CO2 during the night, which lowers the pH. During the day the use
CO2, which raises the pH
Re: anyone have problems with Crushed Coral substr 
. Think of it this way. If he does water changes, which he seems to have done, the Ca and Alk would have to go down, as the IO mix, for example, is only about 380 mg / l Ca. His Ca and Alk seem to go right back up....correct ....or did I miss something ? I would assume he has tested his kits in a fresh mix...correct..? *And I saw where he said he has not added sup's for a long time. *So something must be going on in the sand bed to cause dissolution....there is no other reason. This is not the first guy to have had this problem. The only answer would be to remove the CC *HE IS USING and use something else. Where did this CC come from ?? 
I just needed to re-expalin something that seems to have been misunderstood
