What does everyone keep their alkalinity at?

[dochow]

I'm using Hana dKH checker and I'm at 7.7 to 8.3. Where do others keep their alkalinity in terms of dKH?

 

[fragit]

I use Red Sea test kit, and keep mine right around 8 dkh. No doser, I manually add about 80 mL of BRS 2 part every morning. Usually drops to about 7.6 in 24 hrs.

I used to keep my param's near NSW levels, so dKH ~ 7.5 for me.

I recommend 7-11 dKH unless it is a ULNS tank, where 7-8.5 is good.

I have been keeping mine between 6.5 and 7.0. You can check other information on the systems on the links below...

 

[BigKid4788]

7.8 - 8.2

 

[AdamNC]

8.5 - 9.0 with auto dosing.

 

[McMullen]

8.5-9

 

[XyPP]

No doser, I manually add about 80 mL of BRS 2 part every morning.

You're able to add all that at once with no issues?

I do yes, and no problems. It's only 80mL in a total 160gal system. It's like a couple drops. I typically dose about half at a time. Like 40mL initially then 30 minutes later the other 40mL. I really need a doser but can't afford one at the moment. Ideally I would dose around the clock.

I keep mine between 8,0 and 9. My tank usually ranges between 1-4 nitrates and 0,07-0,15 phosphate (it's not ULNS). I'm trying to reduce the oscillation range to 8,5-9 by adjusting the kalkwasser reactor and calcium reactor outputs to the tank.

Happy reefing

I try and keep it at 8.5, but anywhere between 8 - 9 is what I look for.

 

[MaiReef]

9 just with ro/di and reef crystals

11 dkh here and grow sps lps like a champ. Zoas not so much

 

[mrtian97]

I am between 7.5-8.0, using BRS 2 parts, auto doser of 160mL per day on 91 gallon total volume. I wish I can reduce the addition.
I add 95mL Calcium daily and stays about 450.
WC 10 gallon per wk with RS Coral Pro.
SPS, LPS are doing great except 1 acan melted and 1 kenya tree not doing well

What's your No3 @Up2no6ood ?

 

[Justin D]

8 to 9

 

[Up2no6ood]

What's your No3 @Up2no6ood ?

right around 5ppm

 

[jeffrey holloway]

Using the Zeovit system. Keep mine around 7.0 with two part dosing each night.

 

[BluewaterLa]

Alkalinity 8.7 dkh
Calcium 440 ppm
Magnesium 1400 ppm
Temp 78
SG 1.027
Nitrate 3-5 ppm
Phosphate 0.03 - 0.05

Feed fish well = good coral nutrients
Addition of amino acid once a week maybe two by hand to boost Lps color and health in a sps heavy system
