Rovster's Custom Reef Savvy build......FINALLY!!!

Chromis GONE!!!!!! Thank heavens!

I also spoke with Hanna and apparently there have been a couple calls about bad alk reagent. Things were going great again as I brought my alk down but all of a sudden I open a new reagent and all through the roof again!!!!! FML!

I'm so upset my corals look like crap again. I'm 99% sure this is what caused my "funk". Salifert Alk kit in hand today. I guess I'm going to start the healing process all over again.

dam that sucks about the hanna meter. I have always done alk with the trusty salifert kit and my hanna phosphate meter says 0, I don't trust hanna lol. As I have heard before, if it ain't broken don't fix it and don't chase numbers. I am keeping my numbers as steady as possible.
 
I hear you but if your tank is doing amazing like mine was with over 50 sps corals and your alk drops slightly you up it slightly to compensate. It was so gradual it's impossible to pick up on. This happens over the course of several weeks. I thought I was crazy! There's a thread on the other forum about this very issue and experienced reefers are getting burned (pun intended:lol2:)
 
Ok. Lemme esplain'......

Back in July I left for a week of vacation. Up until that time tank was on cruise. I had a legit growth spurt. I got back from vacation and tank looks great, grew like crazy. I check my Alk and it was like 2 dkh lower. I figure I was gone a week without testing, maybe I missed something. So I proceed to up my dosing. Tank keeps doing great I'm thinking I'm in for a growth explosion. Alk keeps dropping and I keep increasing the dosers. Things start looking weird out of the blue and my Alk is a little elevated so I figure I pushed it too far and back off. Things start to get better over a few weeks and my Alk starts to drop so I go back to increasing to what I had backed off. A few more weeks go by then all of a sudden things start looking bad again. All parameters look great. Tank starts looking bad and some pieces are looking terrible, and I'm thinking here comes another unexplained funk. I start checking Alk every day to really keep a pulse on it. All this time it's been rock steady. It can't be Alk right? I run out of reagent and on the very first test, bam Alk is through the roof! This can't be right?? This new reagent must be bad. It was my last bottle but I just don't trust it.

I go to all pets and buy a Red Sea kit to see if I can make sense of this. Red Sea kit agrees with new reagent! Oh crap, the last reagent was bad and the new one is good. So I get my Alk back down things start to look better and now Alk starts to drop again. Ok, makes sense now I'm getting back to where's I was. WRONG!!!!! This bottle was bad as well. I had by that time ordered more reagent and when I ran out of the one that agreed with Red Sea kit the new reagent read Alk through the roof again! I'm talking from one day to another. I test every day to every other day when things are not going perfect. You don't get a drop of 2dkh in one day out of the blue.

The problem is all this time the readings were consistent. It's so gradual you hardly notice it.

At this point I researched this and apparently this has happened to a few really experienced reefers.

I called Hanna this week and they told me they've gotten a few calls about this very issue. They asked me the lot number of the reagent that was bad and it matched the lot number of another customer that called complaining of the same issue. I basically went through 3-4 bottles of this bad stuff and I was creating a roller coaster of Alk swings (gradual but significant) and all the while I'm thinking my Alk is rock steady.

This is where's the Salifert comes into play. I'm going back to Salifert for the moment because the way the sptest is done it lends itself to being more accurate then the checker. My plan is to eventually go back to the checker but I'll likely spot check with the Salifert from now on. If you research the Hanna Alk Checher you'll see some people complain of drifting readings as you near the end f the bottle.

I've been using the checker for a couple of years and every time I open a new bottle, it's always agreed with the last. The last 3 bottles I went through the new bottle read way higher than where I thought my tank was.

So there. I not crazy, I'm not overly anal. I am glad that I know now what is going on. If I'm being honest, this is exactly what happened when I had my unexplained funk. Same corals looked the same exact way. I thought it was a nitrate issue, now I'm doubting that.

You understand now viejo?
 
Well now I see....literally why I loved my Hanna checker. Did my first alk test with Salifert yesterday and I was unsure of when the thing changed color, lol. Based on what I think it's close enough to my Hanna so I may just spot check with the Salifert a couple times a week just to make sure my Hanns is still on point.

The woes of the colorblind.....
