testing magnesium above 1500ppm

[mfinn]

What test kit will test magnesium above 1500ppm?

I have an Elos test kit and it will go over 1500.

Will they go up to 1800-1900?

 

[amore169]

It will go as high as u want, the way it works is counting drops, but u will run out fluid quicker than expected if ur Mg is so high.

I can test as high as I want with my red sea test, but like amore said, you run out of reagent fast if you are testing high levels.

I have a Red Sea test kit, but after just glancing at the instructions it looks like the mesurement chart only goes to 1280?

Figure out how many PPM each drop equates to and write up your own chart for high levels. PS each drop is a line on the chart.

Thanks

You can use 1/2 the amount of test water, when to the color, read the chart and multiply by 2, a little less accurate, but test kit will last longer.

More than one way to skin a cat!

 

[RBursek]

If a drop count test kit, you X the drops by 2, not the Mg reading, to get the Mg reading. For using 1/2 the amount of test water.

No need to test above 1500. Just let it drop below 1500.

I've got a small problem with bryopsis growing in my zoanthids and it is driving me crazy.
I'm trying the Tech M approach with high mag over a 2 week period.

 

[roshi719]

I tried that, and it came back once my mag dropped back down. I found it was easier to just frag the zoos off of the plug or rock and remount them than it was to battle it in just a couple spots.

My thoughts exactly, but I figured I could knockout the bryopsis first to eliminate transferring it to the new mount.

 

[roshi719]

I just pulled as much off with tweezers first, then fragged and made sure to get as little rock as possible, then I gave them a drp or two of lugol's and let them sit out for about five minutes. Then I rinsed them in a tub of tank water (discard after rinsing zoos in) and put them in the frag tank. That was a few months ago, and I have been bryopsis free since. HTH

 

[mfinn]

Do you think the lugols had anything to do with killing any trace of the bryopsis?

Straight shot of lugols on the frag, without rinsing, sitting out of the water?

 

[roshi719]

I believe it may have killed off any stray spores or strands that got transfered in the fragging. However, I did try the lugol's on the original plugs with the bryopsis growing on them. It killed it back, but it came back after a few weeks. I have been told that the old plugs were most likely had phosphate in the outer layer (from high nutrient system they were previously in) and it was directly feeding the bryopsis, hence why it didn't grow anymore once the old plugs were taken out of the equation.

It is a similar situation to what can happen to live rock when detritus is allowed to accumulate in it. they surface gets loaded w/ phosphate. This is why many people "cook" their rock in vinegar or another mild acid solution. It dissolves away the outer nutrient banked layer leaving clean phosphate free rock behind. HTH

 

[mfinn]

Ok, going in a side ways direction with the phosphate angle, do you think that some frag plugs attract phosphate more that others?
Say,,ceramic vs. aggrocrete?
