What else needs to be dosed with 2 part

[Randy Holmes-Farley Verified Community Expert]

To keep my parameter stable, I dose Alk 170mL and Ca 95mL per day, this kept my Alk 7.6-8.0 and Ca 440. Do I need to increase my Ca dosing to equal volume or just let it be. All my corals including sps are happy, fast growing, especially my 3 montis and Red Dragon, birds nest, etc.

There are some reasons where demand is not exactly equal, especially water changes with a mix not matching the tank. If you have determined over a long period of time that this works for you, keep doing it.

Thanks Randy, I tried to increase my alk but decided not to since I am dosing high amount already. I use red sea coral pro.
I also dose Magnesium about 7mL per day.

Stronim makes your coral stop growing and makes it grow more thicker, I would watch Magniusem levels , because that is very important, also I'll be reading up on iron and and potassium to dose , and I will try it my self

I disagree strongly. A two/three part is designed to be dosed based on alkalinity measurement alone. Just like a CaCO3/CO2 reactor or limewater dosing is set by alkalinity alone.

I wish you were my O Chem I and II teacher ‍

lol I didn't like organic chem. It was taught to me as pure memorization.

Yea it was a tough two for me.

Can someone verify that the red sea is 5x more concentrated than the brs calcium chloride per gallon. That just doesn't seem right to me so looking for second opinion. From what I gather it takes 2.2 lb per half gallon solution, one ml red sea solution raises calcium 2ppm in 26 gallons of water. When I punch raising the calcium of 26 gallons to 2ppm from 0ppm in the brs calculator it requires something like 5.5ml brs calcium chloride

Calcium chloride solutions can be made very concentrated. I do not know this one in particular, but it certainly can be.

My recipe, which BRS uses, is more dilute so that the alk part can be dosed in equal volumes. Sodium bicarbonate and carbonate are much less soluble than calcium chloride.

I found out that Iron helps with Macroalgea growth, while potassium helps bring out the color in corals especially the blue colored ones.

Iron can certainly help with macroalgae if it is depleted, and I dosed it for years.

If (and only if) potassium is depleted, it is worth adding to maintain natural levels (mine never depleted), but I do not believe the connection between any specific dosed element and any specific color.

One of the reasons I was asking is if a calcium solultion can be made more comcentrate then it is possible to dose non equal parts but still be dosing two part in the corect ratio. What is the correct alkalinity to calcium to magnesium ratio. I believe alk is the comtrolling factor in calcium level? Calcium just precipitates out depending on alk?

That is good to know about the strontium, guess I might have to buy a test kit and see what my levels are
