Alrite so I've been having this problem for over a month. Tank has been setup for about 4-5 months. Its a 90 gallon, no sump, aquamaxx hob skimmer and 100+lbs of live rock. I run a aquamaxx cone-s HOB skimmer which qorks amazing. Anyways I have one tang in there and am about to take a pair of clowns out of QT.
Now on to the more important stuff. Its pretty heavily stocked with sps frags and a few baseball sized colonies.
The problem is according to my hanna checker my calc is maxed out- 600ppm+.
Dkh is about 8.5 right now and I have been dosing esv alk part every day as the tank eats up about .5dkh per day. However I cannot get the calc to drop and I think it is inhibiting some coral growth. Corals all are healthy, good polyp extension but they do look a little pale, but not bleached. I had a little flatowrm issue so I treated and I did a 30 gallon water change which I thought for sure would bring my levels back in check. It didnt......
So I really don't know how or why my tank isn't using up calcium as everything is growing.
Initially I thought the hanna checker may be defective but I checked a bucket of fresh mixed IO salt and it popped up with 400ppm which is,prolly close. However, I have an API calc kit that contstantly reads 460-480. And that always reads the same so I think the calc is not being used up in general.
Temp is 79-80
PH-7.9-8.3. Lately it has been hangin more near 8.2 around the clock because I have been tryin to raise alk levels.
Magnesium sits around 1360-1380- salifert.
Any ideas would help a lot or if any of you guys have had this problem let me know. My tank before I ran for years with no problems like this and I used equal parts of ESV with no problems whatsoever. I tested once a month. I'm pretty confident once I can get calc back in the 400-440 range I'll be alrite.
Thanks for any help.
