Based solely on a list of numbers I’d say
Ph- low
PO4- high
Nitrate- fine
Kh- fine
Mag- low
Cal- low
But im a reef keeper, (well, not currently, but I’m working to get back there)

That would help you with flow, but not gas exchange. That would only help circulate the air that is already under the lid into the water. So, if your tank needs more flow, absolutely add it, 2 pumps are better than 1, you can get more turbulant even flow that way. For your ph though you need to find some way to get your water access to more air volume. Some people run a tube outside so their skimmer is sucking in fresh air from outside. Pretty much anything to help it get more air with less co2.
If you have a cheap air pump, you can verify this is the issue for sure before getting too crazy though. Just kick the pump on, tuck the tubing under your lid and aim either your return nozzles or the mp40 up a little so it ripples the heck out of the surface for a day or two and re-test. I would also get another ph test kit and make sure it agrees with your other one though too. Just in case you are getting a false low.

Well I am back. I have Seachem reef advantage magnesium. My magnesium is 1180 and I want to get it to 1400. It says not to dose more than 80 liters per day. What do you folks say. I want to thank you ahead of time

Bump it 30-50ppm every other day. Hopefully they meant milliliters though lol.
You must be proud of me. Doser set for 50ppm every other day. Now for the kalkwasser It says to start with 1 milileter per liter. My total system is 260 gallons which equals 984 liters so what would you recommend I dose. I am going to have to get you a Christmas card this year. And really thank you so much

No worries, glad to help!
Be careful not to forget about that doser when you get back where you need to be!
Dosing kalk is going to increase your alkalinity and calcium levels, so how much you can dose is going to be based on how much alk your tank uptakes a day. I would start with half or a quarter the recommended dose, do that for a few days and see what that is doing to your alk levels and work up from there.
I did the kalkwasser calculator. It said just under 1900 mil a day. So I took 900 and divided it by 24. It came out to 38 mil 24 times a day. How do those numbers sound. I am trying to run with the big boys now. Again thank you
I have a question. In my sump I have live rock and I have something on it that looks like cellulose insulation. When I move the rock floats around in the sump. Any idea what it is and what I can do to get rid of it. Thank you
I was wondering if you could help me out with my magnesium numbers. I have seachem magnesium and a 450 mil dosing resivore My system is 260 gallons all together. My magnesium was tested at 1107 and I would like it around 1400. For the life of me I can’t figure it out. Seachem sent me a calculator but I can’t figure out how to use it. Any guidance would be greatly appreciated and thanks.

Sure, i assume you are using their reef advantage magnesium product. Plugging this into the calculator:
Means you need to add 3618.6 grams of their product to your tank to get from 1107ppm to 1400ppm. This would be best done following their advice of no more than 25 grams per 20 gallons, you *could add up to 325 grams per day, i would not add that much and take it a little slower.
Your 450ml container holds roughly 2 cups. They recommend 1 cup for each 25 grams, so mix 50 grams of powder in that container, and you can dose it full tilt 4-5 times per day, measuring your mag every other day until you hit 1400ppm. At that pace, (200grams per day) should take about 18 days.
Also from their page:
DO NOT OVERDOSE
Do not exceed 25 g/80 L (20 US gallons) per day. Excess magnesium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if magnesium & carbonate additives are added on alternate days or at least 30 minutes apart.
