Looks good to me, I keep my PH and KH on the higher end too for coral growth. the only thing to watch is your Cal and Ma are on the lower side for coral growth. Cal at 450, Mag at 1360

OK, will dose tommorow!

I presume " na" = Nitrates if so maybe best you bump those up a tad,I see often alot say 0.03-0.1 po4 and 5-10 n03

there is a relationship with Alkalinity with flow and light, which is one reason why we see successful tanks with Alk in a wide range and failing in the same range. One thing seems to be true, stability can be more important than the amount of the the ions. So be careful with chasing numbers - IME user error reading test kits is common and can lead to unintended consequences

Speaking of that if I am reading your numbers correctly NO3 (and PO4) reading at 0 can be a disaster. Corals need both and bad stuff (pest algae, cyano and dinos ) show up as they can outcompete corals in stressed environments. That being said, API saltwater test kits are notorious for not being sensitive enough (ie read zero) for reef tanks.

Salinity 1.025 I run my mixed reef at ( only young tank at 9 months old so need lots more coral yet) and 25-26 °c temp

one more point, if you agree with Red Sea and others, the ranges for your numbers also should coincide with the types of corals you have, ie sps, softies, mixed etc. What numbers works for one member may not work for another if they have different types of corals in their tanks.

NSW levels work for all corals.
I see no need to be higher than
8dkh for anything. That includes growth rate and mixed reef systems.
You can run low levels of no3 and po4 if you feed your fish enough and have a heavy export system in place.

Remember that no3 and po4 levels we test for and get are what our export system is not removing.

Good no3 and po4 levels and the big 3 that work for all corals are:
No3 <5
Po4 <.01
Alk 8
Ca 420
Mag 1350

Dont get caught up on numbers.
Pick your levels and focus on keeping them stable is the best advice I can give.

I would ask what are you using to test these parameters?

As said above the No3 and Po4 should be detectable but not high.

 

[MichaelReefer]

DK is a bit high. PH is fine. I run mine higher as well.

I would suggest you up your nitrates(No3) to around 1-4 ppm and phosphates(Po4) to at least detectable levels around .02-.05. I found that by putting a little bit of food directly in my filter floss during feeding and only changing 1 pad a water change keeps those at the levels I'm shooting for.
