Acro help!

You may want to wait on dosing until you have the magnesium. The problem with low magnesium is the tanks inability to sustain higher alkalinity and calcium.

Will it hurt the corals for the alk to keep dropping? It will be tomorrow before i get some Mag.

I will get some MAG sometime this week to get that back up and i bump the alk doser to 30seconds of each hour for 10hours(5ml). BRS calculator says i need 30ml a day but i will test again tomorrow to see how much it dropped again.
Cal doser is still at 10sec dose for 10hours(1ml).

You can go to get Epsom Salts at any Drug store to raise your Mag up just do not use it all the time as it will raise Boron levels if i remember right. Should be able to find a dose chart on the net.

I am getting some brs 2part magnesium this afternoon. I plan on bringing my Mag from 1290 up to 1350-1400. I will bring it up over a couple of days to not shock anything.

I've got plenty of all the BRS 2-Part additives if you need any. I bought tons of it on the last group buy to sell to the club at the discounted rate. :clap2:

The alk dtopping on its own won't hurt them near as much as bringing it up too fast.

That is to high for a target mag, 1300-1320 is good.

Some people would argue that your mag of 1290 is high or perfect

You can maintain an sps tank with kalk only plenty of people do it. Bart had an sps tank with only kalk. My tank odds fine with only kalk.

Yesterday's alk
7.72dkh(dosed 5ml)
Today's alk
7.95dkh(adjusted alk to 2.5ml)

I dosed 600ml of 2part mag today to raise it 50ppm(per brs calculator).
Thanks Daniel for the Mag!
Tested mag(salifert)
1290-1320(0-30ppm gain).

I get the par meter in 2-3weeks to verify the proper par level.

I will test again tomorrow to zero in the proper amount to dose for alk and verify mag levels.

I am determine to overcome this issue one way or another

I run mine between 1300-1400 and have no issues.

 

[greg0385]

Thanks Ryan, i have read alot that people keep their mag at the same level as your saying, so i feel pretty confident in having my mag goal at 1350.

That's my goal, 1350 +/- 50. Mine is usually closer to 1400. ALK 8.5 CAL 450 and I run bio-pellets

 

[greg0385]

Thats the type of params im looking for, maybe a bit less alk(8.2).

I've had my ALK up at 9 and things looked awesome. I was previously running it between 7.8-8.2 but now my goal is 8.5-9.0 after seeing how great things looked when it spiked that high one time.

 

[greg0385]

Im too worried about burning tips at higher alk levels or i would raise it higher.

9dKH would be the maximum I would consistently run in an SPS dominant tank and IMO would be fine.

 

[greg0385]

I will keep that in mind, but will start on the low side(8.0-8.2) and maybe one day get the nerve up to raise it up to a higher alk #

I thought I needed to run a lower ALK until I traveled one day for work and my dosing pump stayed on and raised it to 12dKh... I expected to come home to a wiped out tank but everything looked awesome. Ever since I run mine closer to 9

Over the weekend i dosed 1200ml of brs 2part mag. I dosed 600ml over a few hours friday and another 600ml sunday over a few hours.
Salifert mag test-1350

I can now scratch low mag off the list of culprits.
Still have to work on:
-lowering phosphates
-checking nitrates
-checking par
-adding flow
-stabilizing params

I have notice some peeling of skin from couple acros. Its not at the tip or base. I turned down red/pink, green/cyan, 6.5k/10k, UV/violet roughly 10%.

My terra del fuego has slowly receded from the center of the frag to the edges. 80%gone

Strawberry shortcake has lost all color and no polyps. Its getting high flow and lights but is a off pink/brown color. Surrounded by colorful acros doing very well.

Still got lots of work to do to get back on track toward having a successful growing acro tank.
