Parameters

[kenand]

90 gallon reef tank.
Salinity- 1.025
Ph-8
Nitrate-10
Alk- 12.5
Calcium-360
Ammonia-0
Phos-0.50

180-gallon fish only.
Sal-1.025
Ph-8.2
Ammonia- 0
Nitrate-10
Alk-12.5

These are my parameters . 8/19. Are these good? And could someone give the list of the test I should be doing on each tank?

The Alk is higher than I would personally run, and the Calcium is a bit low; the Phosphate is high too.

The quote below is from the mod of the Chemistry forum here on Reef2Reef; it has recommended ranges for parameters (the only thing typically considered important from table 2 is Nitrate).

For both tanks, you can largely ignore Magnesium, and Ammonia - once the cycle is complete - should really only need tested in the event of an emergency (such as fish deaths, massive overfeeding, etc.). For the fish only, you can also ignore Calcium and Alk (unless you have inverts like shrimp or crabs in it, then it would probably be wise to test those as well):

Take calcium to 420 and alk should have a slight drop although its not too crazy but keep it closer to 11 -11.3
You may not have too many coral which is absorbing the alk content
How are you measuring numbers?

Thank you so much for the advice on getting me on track for what to keep to keep on my charts. What do I have to do to bring alkalinity down and phosphate down? Calcium up? You've been a great help.

For bringing Alk down, time and water changes with lower Alk water (i.e. you lower the Alk of the water in the mixing station before adding it to the tank):

Assuming the alk is high, it was suggested earlier in this thread how to lower it using acid, such as muriatic acid or sodium bisulfate to treat new salt water to give very low alk.

I’m going to remove the emergency tag as that alk level is typical of high alk salt mixes.

If you want to lower it, I’d either use a different salt water source, or drop it in the store water using sodium bisulfate or muriatic acid followed by plenty of aeration.

For the Phosphates, a lot of methods that reduce Phosphate levels also reduce Nitrate levels, and your Nitrate levels are fine; so to reduce Phosphate without reducing Nitrate, I'd probably use a Phosphate binding media like Aluminum Oxide, GFO, Lanthanum, etc.

Personally, from what I know of these options, I'd personally probably use GFO, but the article below may help you decide what you think is best (particularly the "Phosphate Export Using Binding Media," "Phosphate Export Using Binding Media: Aluminum Oxide," "Phosphate Export Using Binding Media: Granular Ferric Oxide/Hydroxide," and "Soluble Metals to Bind Phosphate" sections):
https://www.reefedition.com/phosphate-in-the-reef-aquarium-by-randy-holmes-farley/For raising Calcium, you should be able to use Calcium Chloride (I'm not sure how much you would need or how best to dose this, but Randy - the forum chemist - and others would be able to tell you for sure there).
