    Your alk is just fine, it actually higher than mine. How big is the tank and how big is the refugium and what exactly do you have in the refugium?

    Tank is 75 gallons, refugium is about 3 to 4 gallons with figi mud and some micro algae

    That explains the swings. A 3-4 gallon refugium on a 75 gal tank is going to have almost not effect at all. I've read a number of expert reviews on the figi mud and the opinion of the experts is that is nothing more then a snake oil scheme, it doesn't really do anything. As for the algae, you need a Macro Algae like Calurpa or Chaeto in there. However, even at that size it's not really going to do much. Do you have sand of any kind in the bottom of it? The reality is, for a tank with a volume of 75 gal you really need a refugium with a 10-20gal capacity for it to really have much of an effect, and even at that the best thing it is going to do is produce Pods but it's not a terribly effective Nitrate reducing mechanism.

    Are you running a calcium reactor?

    No, but we do have a kalk reactor

    What are the details for your setup? I'm kind of working blind here. LOL Give lighting (amount and type), coral types, sump volume, anything and everything will help. Are you using a deep sandbed, how much live rock and how old is the tank? Those will all be important as well.

    Lighting is metal halides not sure of watts, 54 watt t5ho actinic lighting, moon lights, hard corals, softs corals, many variations, 25-30 gallon sump, we have a deep sand bed around 5 -6 inches, 100lbs of live rock, it has been set up about 2 years, stocked for about 1 1/2 years. We also have a clown fish, a foxface fish, a velvet wrasse, a yellow tang and a couple of other fish that I am not sure of the names, we also have snails, shrimp, hermit crabs, and an urchin.

    Have you experienced any troubles resulting from the pH swings? If not, then I wouldn't really worry about them too much. You pH is not dipping to dangerous levels. If it was then I'd worry but It's not really that bad. I know people who are extremely successful reef keepers who have a 180gal reef that stays at about 7.96 all the time.

    Haven't really had any problems. Most stuff we read says Ph should stay between 8.0 and 8.4 and a shift of more than .2 is not good. Just trying to stay on top of these things since we are new to keeping the aquarium. Lots invested, don't want things to crash

    How long have you been having these shifts?

    Not really sure, used to test daily with the test kit and it tested fine. About two weeks ago, we got a Ph monitor that shows constant Ph readings and we noticed the change between day and night. Could have been going on all along, not really sure. That is why we are questioning whether this is okay or not
