reef crystals absolute junk?

[Wick]

testing my Alkalinity on a fresh batch of mixed water with reef crystals and it is coming up as 0. I tested Alkalinity straight and it showed that there was alkalinity present. I'm using a red sea test kit. Anyone else have this problem?

Expired test kit? User error?

RC usually has very high ALK.

RC usually has very high ALK.

07/21 it expires. used 5ml of tank water then drop, shake, check for blue or yellow. and repeat till yellow.

200g box, 160g pail, or 50g bags?

If it was a pail, you might want to try and roll it around to mix it up. Stratification is a real thing, BRS did a video on it.

Other then that, maybe just a bad batch? It's one the reason I switched back to regular IO years ago.

200 gallon box. This is with straight alk. I'm really thinking this killed 80 percent of my corals. I was using fritz red box a while ago. Like 5 months ago everything was good. Frustrating.

Calcium is pathetic too. Hanna checker

Are you sure salinity is good?

Those are some bizarre numbers you're getting their. Maybe it is a bad batch of salt. I would try contacting the manufacturer to see if there has been any issues/recalls recently.

Ive always used reef crystals without any issue.

Definitely numbers are way off. Check salinity.

Is regular IO less prone to bad batches? Been thinking about switching from RC, mainly because I dont want organics sitting in my mixing tank. But I haven't had a bad batch of RC yet. I always measure alk when I open a new 50g bag and it's always between 9-11 when mixed to 1.026.

mixed at 1.025 for 20 gallons. with heater from night before and pump moving water. i bought fritz blue box from LFS which i used to use. Going to test out this once its mixed and get my coral into hospital tank. (20 gallons)
