hanna alk problem?

[klp]

If you REALLY want to know about your water to establish a base line, send a water sample to Triton Lab. It will cost but it is a way to be sure of what you have. There are also videos on the site. If you let the first video run it will bring to choices. There is a 9 minute video interview with them and after that a 48 minute video from BRS at MACNA 2014 where lecture is given. The speaker is a little hard to understand but doable. Hope this helps.

My alk has been testing low with my Hannah checker 93 ppm or 5.1 dkh. I've been going crazy trying to remedy the problem. I tested mag and it was down to 1150, so I dosed a bunch over a few days and got it to 1250. I also dosed some baking soda to bring up my all and made my kalk solution a decent amount stronger than usual. After a few days, I got my alk up to 126 ppm or about 7.0 dkh. I tested tonight and my alk was back to 93 ppm or 5.1 dkh. Ran the test again and got the same. What the heck!???

So I broke out my salifert alk test and tested twice. 10.5 dkh both times. My Hannah reagent has either gone bad or my tester has gone bad. I never had an alk issue this whole time! I did have a mag issue, but that's another story.

All of my corals actually look good. Decent PE and everything. Right now, I'm filling up my top off container with RODI to dilute my kalk solution. I'll let my alk fall back down to around 7.5 to 8.0 over the next few days. I run biopellets so I don't want to be above 8.0 or so. Sound good?
