water parameters for mixed reef

[kraken]

Having read lots of thread and googling.

still having inconclusive 'ideal' water parameters for a mixed reef tank.

What I gathered:

NO3 = zero

PO4= zero

CA= 430 - 450

Mg = 1300 - 1500

Ph= 8.0 - 8.3

KH- 8 - 9

My question is, do you guys maintain the parameters at the higher end or lower or in between?

I gather for ca, kh & mg i like to keep it at a mid range... For example i like my mg to be at 1380, i keep it about 1400 to allow a buffer in case of changes...

No3 n po4 if u can get a low range checker, keep it just slightly above 0

Unfortunately i dont keep tabs on my ph often...

I personally thinks 0 nitrate is bad. I maintain my nitrate at 2ppm..It's never good to strip the tank too clean.

my No3 is zero, well at least not detectable by my test kit.

PO4 is between zero and 0.25

I read also that some do prefer to keep their tanks with a little of nutrients.

by far in my tank, the zoas (and other LPS) and some SPS are doing fine with growth and colours (not very vibrant colours on sps though).

I have high bio load of 17 fishes (including bombers like naso, BT and YT)

feeding twice a day. manage to keep NO3 at bay, but PO4 is still detectable.

What test kit you use?

[kraken]

NO3 n PO4 is lousy API

The rest is Salifert

Bro, I use API which test 0 but for tetra test like 25 - 50....faintz.

cannot be such a big difference in readings.
