To low nutrients (no3)

[Charlie Denmark]

Hello and happy Easter to you all.

As statet above I'm having troubles whit to low no3. It used to be around 3,5-4,5 but then I did start to add fe/sink/iodine and so on, following Tritons correction sheed after my last test.

This resulted in MASSIVE growth in my macro algaes and my corals :-) but.... The no3 did fall rapidly due to the growth. It is now around 0.2.....
So now my no3/po4 ( red field ratio) is a little off balance ( my po4 is around 0.045).

This again resulting in a little pale sps' and my lps' also looks a little to to poor side.

How would you experts handle this ????
Add no3?
Turn down the light periods over my macro algaes?
Remove some po4 whit Triton gfo?

Give me your thoughts on this one please.

Greetings Charlie

You can increase your fish load/feeding, reduce photoperiod over the algae, reduce the amount of harvesting of algae.
