Sorry about the Goby...can't believe he wouldn't eat the blackworms...my fish were in love.

[/media]Thanks again for all of your responses. In response to the air/ light on or off variable I think that they are both not factors. In one of the link on PH there was a test in which you place some of the tank water with bubbler in house and check ph and then new water and place outside and check ph to determine O2 saturation as the problem. I did this test and found that it was not a O2 problem. I thought that was a great way to check that. Anyhow, Ph is back to 8.0 but really hasn't been a concern for me since I had the impeller on my skimmer and the main intank pump break in just a few days, so ph has taken a back seat. [/media] Note the incredible amount of algae that has taken hold since the skimmer shut down. But all in all things are still not dying yet...now to go and spend lots of money online, on new equip. This is of course right after I ordered new LED bulbs last week. When it rains it pours.

Great articles Chad. I am trying now to learn all of the factors but I think that turning the AC on full time might have been the major factor. I've made some changes and things are slowly moving up. I also took some water to the LFS and had them check the Ph and it was still a bit low. Again thanks for the suggestions of things to look at.

I woke up this morning and noticed that something was wrong with some of the corals in my tank. Even after half an hour of the lights being on an encrusting grass type coral wouldn't open. I also saw a bristle star out in the open. IMO sure signs of a problem. basic info-- 90 gallon with 75 gallon sump Parameters PH -7.7 (was 8.0 the day before) No nitrates, phosphates Kh- 9 Ca- 420( i think its ppm) My question is what would have caused the sudden drop in Ph? The day before just happened to be when I decided to do testing. I didn't dose Ca in the past two weeks b/c my Kh and calcium were good. My test kits are new except for Ph but I've been using that one lately and it seems to have been working and showing normal results. Is there a good website that I can just learn the chemistry and stop guessing? Gmubeach told me to dose a ca/ph upper slowly but I don't get why with a solid Kh and Ca in the tank I should have a low Ph? Anyhow, I did what he told me and the the thing wavy coral thing has started to come out. Thanks for any suggestions...esp if you want to give me a chemistry lesson Myra
