Recommended Macro Water Parameters

I found this at:
link

Temperature: Between 23-28 °C ( A higher temperature will stress most macroalgae species and can damage them )

PH: 8-8.4

Alkalinity: 8-11

Salinity: 1.024 - 1.026

Nitrate: Between 3-10 ppm, minimum 2ppm

Phosphate: Below 0.5 ppm, good is 0,03 ppm, minimum 0.02ppm

Magnesium: Around 1200 ppm - 1350 ppm

Calcium: Around 400 ppm - 450 ppm ( high levels are important for calcified species like Halimeda)

Iron: Around 0.01 ppm

Iodine: around 0.04 ppm

That's a really good article, thanks.

It's good to have some numbers to shoot for

greg10 · 11/02/2020, 01:36 PM

My latest numbers ppm
Phos 0.03
Iron 2.23
Nitrate 100

Nice greg10! Now folks have some numbers to shoot for. Very helpful!

greg10 · 11/14/2020, 08:14 AM

Numbers this week:
Phos 0.08
Nitrate 50
Iron 0.70

I added NeoPhos, no nitrate or iron added.
Lots of iron consumption
my display is at 0.02 iron

greg10 · 11/21/2020, 01:44 PM

Iron 0.3
Nitrate 100
Phosphate 0.08

greg10 · 11/29/2020, 06:44 PM

Iron 0.24
Nitrate 50
Phosphate 0.09

Did you notice faster macroalgae growth with high nitrate?

greg10 · 11/29/2020, 10:19 PM

Yes, things improved

I had been at 0 phosphate and 0 nitrate and 0 iron

greg10 · 12/12/2020, 11:30 AM

Iron 0.12

Phosphate 0.00
