Well uh, I’m clearly doing something wrong. If says to shake vigorously but maybe I have too many bubbles.

I have trusted the old guys there from the beginning and everything they have told me has been absolutely spot on. They have a ton of expensive corals, for display and for sale and for farming, and use the exact same RODI water and saltwater for all their tanks as what they are selling me. I trust that they have a massive financial interest to not **** up.
Wait you're close, what LFS? Nemo's Reef?

@Robin Haselden do you go all the way with the 1ml syringe. I think that’s where I’m going wrong. Not sure when to stop.

I’ve gotten a reading of 540 and now 541.

Seems like I’m mostly doing it right given the consistency but not quite there.

With the 1ml syringe you want the bottom of the plunger(ignore the stem, look at the bottom seal) to reach 0 at the back of the syringe. It reads backwards, it's a titration syringe. The scale is reversed to read how much you've squashed out.

Anyway, suck up the reagent until the bottom seal is at 0, then put all of that in the curvete and fill to the line with RODI. You know what a meniscus is, right? Always use the bottom of the curve in the water surface.

I'm not laughing. I've been there.
Not at him. Robins earlier post about what would happen had me cracking up, then when it did that was just too much. It’s also a feeling of relief, because i almost got one of those! Went Salifert instead after reading reviews.

For the 100ųl syringe, when collecting a sample only push to the first stop. Slow the plunger to fully extend while holding the tip under water. Then when aging the sample to the curvete, press the plunger fully to the second stop. That will make sure the entire sample gets squashed out.

Oh no, I've had Robin walk me through something on the phone. I was panicked and Robin was chill.

That I have down, I was inquiring about getting the full 1ml of regent a.

The only thing I can think of is I’m using distilled water that came with my Milwaukee for calibration.

Maybe I should give rodi a shot? They say not to.

I’m an idiot, I’ve spent a whole hour testing this when I should have just done the water change.

My corals are going to be ticked off for another day, I hate seeing this :/

My fourth result when pulling the syringe where the left most black ring lands just above the .1 notch.

I’m just going to have to test this against my new batch of saltwater tomorrow until I get it accurate.

My worst fear is that alkalinity and calc are normal.

One thing I am considering is that maybe the lights have increased in intensity from being on acclimation (running acclimation until April just to keep the intensity lowered by 35% on a preset).

Maybe phosphates have bottomed out again as well, getting too late to test :/
