New Coral Tank, Parameters up and down

[mathatrick]

Hi

I have a 450l salt water that is about 5 year’s old.
It was a fish only tank and now I have started on some corals.

I use natural seawater and do a 10% water change ever week.

I am trying to keep my param as followed:

KH - 10
Cal - 450
Mg - 1500
Phos - 0.01

So I have been testing and some days I dose and some days they rise on there own. Please see attached sheet, is this normal for coral.

I have:

3 torches
3 Zoa
1 hammer
1 GSP
1 mushroom coral
1 Acan

Any help will be greatly appreciated.

What are you dosing? Also that phos is really low for torches and hammers

What ever is less than what I want in the parameters I mentioned above. I am using Red Sea Foundation Supplements. I am currently using Rowaphos, do you suggest I remove that then. Everything seems really happy at the moment.

If everything looks happy don’t do anything.
