any recommendation in helping me raise the ph without affecting the alk or ca?

You can still vacuum sugar sand, but it takes good technique.
Use a short hose so you can put your thumb over the end, or use soft hose so you can pinch it (you can get different wall thickness, thin is easier to pinch). Buy a vacuum with a small hose, like 1/4" ID so the flow isn't so fast either. Then just shove it into the sand, and as soon as the first bits of sand get a little way up the vacuum pinch it off so the sand settles, you can play around with it like that and get the detritus out without the sand.
I bought a vacuum (I think Hagen..?) that uses a 1" pipe for the vacuum part. I bought a 36" piece of 1" pipe (it's used for undergravel filter uptakes) and cut the pipe to be just a tad shorter than how deep my water is. Looks really well. The extra length helps to get the detritus out while leaving the sand in the tank.
Low pH has many causes. The most common being either high bioload or too much CO2. Do you ever open the windows in your house for fresh air? Check for an oily film on the water surface. Pretty much any skimmer works well for off-gassing CO2, but if the house has concentrations of CO2 then all the off-gassing in the world won't help. Bioload also lowers pH as fish poop is acidic, and there are also acids released when organics are broke down through the nitrogen process. Sometimes if everything is "good" simply dripping kalkwasser at night as part replacement for calcium and alkalinity dosing will keep the pH from falling so much at night which enough to keep the pH higher during the day too.

I have plenty of critters in my tank that help keep things clean, but they don't make up for the fact that the tank is a tiny closed system, and not a giant open reef. As far as I am concerned the sand is purely aesthetic. Stuffing a few animals in the tank doesn't make up for what I consider to be good maintenance practices.
Good info but some of us lazy reefers do things different. oops I huess were kinda hijackin. Maybe the moderators will clean it up for him.
