So is this to imply that higher ph can be indirectly related (although not directly caused by) higher levels of oxygen?

That's what I was afraid of.

That's just the point. I've been able to lower it with soda water but it is only temporary. There is obviously a core source. I'm due to switch out some aging vho bulbs. Anyone heard of old bulbs raising ph?

I have used a well calibrated ph probe and have ruled out testing as the problem. Good suggestion on the dkh test. I don't think it will be the case but I will double check to be sure.

You didn't confuse me but only after I read it twice! Great information. Surface agitation is not abnormal but could be reduced. It sounds as though an airstone in the sump (suggested to me a while back) would actually raise the ph? I've used it sporadically but have noticed no effect on ph...

I have had it tested at my LFS and used three different methods on my own. All showed high ph.

Soft corals have been OK, although they are not as vibrant as they used to be. I have a large leather coral that has been a little more affected. Also my Bubble-tip has really suffered. It stays alive but hasn't looked well in weeks. The anemone was the first to show signs that something was...

I'm assuming that with dkh readings of over 11, I'm well buffered. Is this assumption wrong?

Actually I am using seawater. We have a supplier that has provided pretty good product over the years. I've actually had more success with it than when I used to mix (not to open up a debate). Anyway, I just tested the ph of some I've yet to put into my tank and it was around 8.45, a little...

I continue to struggle with ph levels around 8.75. Including some of the obvious reasons, what are the causes of high ph. I've gotten everything I can think off at the right level and stabalized but can't get my ph any lower for more than a couple of hours.

I've gotten my Alk and Ca levels good and stable for over a week. Attempts to lower the ph with soda have had only temporary success. It generally creeps back up to around 8.7 within a few hours. What could be causing this high ph? I'm absolutly stumped.

I'd been using Seachem Reef Complete until I ran out (can't get it locally). I'm now using Seachem Reef Calcium. For Alk I've been using Kent Pro Buffer. I've planned to switch to Kent CB once I get things a little more stable. I've tried three different tests (Salifert, Aquarium...

Any thoughts on my chronically high ph?

I have a 60-gallon reef tank that has been running in its present configuration for over three years with little to no problems. But the last couple of months I got lazy and let my tank get out of control. Ph was (and still is) consistently over 8.6, Alk and Ca got real low. The last couple...

I have just installed a Mag-Drive 7 inline and it is shooting a fine stream of air bubbles into the tank. I first thought it was my bulkhead fitting's close proximety to my skimmer outlet so I experimented by removing the skimmer leaving the sump empty but that didn't help. I have a straight run...
