Tested this AM. Twice with each.

Salifert:
Both tests came out at 7.8dKH. This an interpolated value. My check solution tests at 8.4dKH, not 7.4 as it is supposed to. The aquarium water prior to interpolating came out at 8.8dKH.

Elos:
Both tests came out at 9.0dKH

pH at the time was 8.24 (Pinpoint).

Hmmmm, I don't know what to believe now. I like the Salifert reading better :sad:.

One other thing to note about the Elos kit....some of their KH kits currently "out there" have an incorrect 5ml line on the vial. It is lower than it should be. So, when measuring the water amount measure to the syringe 5ml line, not the vial line. I have one of the screwed up vials.

Cheers,

Yeah I don't which to believe either now :(

With mine though I find it hard to believe the salifert test because for one it was inconsistent but also after many days without kalk and very little alk dosing, the alk had to of dropped. If I go with the Elos, it has dropped to 7. Which is perfect :)

But I don't want to only go by the Elos kit just because its giving me the number I like. Running ZEO with a high alk (over 10) could kill my tank!

On another note, I found the K+ test from Korallen Zucht to be very easy to use and seems like a very well put together kit. Although I have nothing to compare it to since I have never tested potassium before now.

Sounds stupid but why don't you take the average of the two tests. Or repeat (2x)the tests to ensure consistency of numbers. I use the KZ test too, but i fiind it hard to read.

No not stupid :lol:

This is what most of the people I asked on ZEOvit.com are doing. They use both Salifert and Elos and either use the average or just make sure both are within range. Many of them said they find Salifert a bit high and Elos a bit low. Actually using both could be the best way to go IMO.

I think my Salifert ALK kit was one of the ones from that bad batch not too long ago :( So going by my experiences with the Salifert ALK kit is not a good idea and I should probably try another one.

I just hate to think about how much I have spent on test kits now! Well over $300 last year :sad: Just the Elos Mg, Calcium and Phosphate alone were like around $120 plus taxes or something. Then the K+ kit was $50 with taxes, ect. ect.

So tested again...

Ca 420
Alk 7
Mg 1300
K+ 320 ish (low but I am dosing potassium)


So safe to start ZEO! But I haven't...I am still so worried to start!

Seems like everyday the past few weeks, the tank has been looking better and better. Coloration is great, growth is great. I am so scared to ruin things. The reason I still want to do it though is that nitrates have now crept up to about 15-20! Jeez. Funny thing is though, the corals are responding so well to the increased nitrates.

Guess I will start tomorrow anyways...I don't want to see where this tank is going if I continue to let the nitrates rise.

Jeez...still no luck. As of tonight...

PH 8.59
Ca 450
No3 10
Alk 8.5
Mg 900 (Dropped quite a bit...not sure how since yesterday :( )
K+ 300 (Dosing potassium but not doing much yet)

Got the reactor in my sump (without the rocks), so just need these darn levels to get right!

Removed my refugium though the other day so I am getting a little nervous about nitrates rising. I had expected to be able to start ZEO this weekend but no luck yet.

I think the Mg test I did must have been wrong. There is no way that could drop like that overnight basically. I did some reading on Mg and it is used up relatively slow. Even just based on the salt I use, it shouldn't be that low. Plus I am dosing Kent Mg.

So I am going to test again today. Actually maybe get a LFS to test for me too so I can compare :)

How many of you running ZEOvit are watching the K+ real close? I know its very important with ZEO and I do trust all the experts at ZEOvit.com but do I really have to wait for it to get to 350-380 to start ZEO? Its at about 300-320 now. I have been told its not a good idea to start until everything is stable at natural sea levels. Otherwise its quite risky.

I have a feeling ZEO means a LOT more testing in the future. There seems to be a big difference in the tanks I am seeing on the ZEO forum that are really keeping on top of things and the ones that are running ZEO but not really caring all that much about keeping levels perfect...the ones taking that extra time are getting INCREDIBLE results.

I guess if I am going to do it, may as well commit and keep on top of testing :D

I guess I would be one that is trying to keep my levels in line but having a hard time with it. I do agree with levels perfect ZEO's results are amazing.
Keeping K levels at or around 400 was expensive and very difficult. That is one of the reasons I switched to RB salt. Because if the higher than average K levels. After the switch I stopped dosing and reading the levels. I guess I really should start back at it.

I know from experience getting the K levels above 380 does effect the corals in a very possitive way

One has to assume that in development of all of Zeovit addatives that effectivness was judge in a tank with perfect levels

J

LOL, I ended up sending a photo to the guys on zeovit.com I was so ticked off at how difficult it is to read the test. He was like "yep you're at 380". I have no idea how he could figure that out from a photo.

I found with my testing that its very important at first, then less important as you go along. By this I mean test often at first, then less often later. Currently I test every 2-3 weeks vs every waterchange (weekly). I'm also using RBS which helps.

Actually yes I have been told that the results of ZEO are all based on keeping perfect levels. I guess they actually "tested" it on a 15 year old tank for a long time to get it to where it is now.

When reading through the ZEO site, I notice way more test results posted than any other reef site I have ever been to. The build threads are all about test results :D. IMO that makes sense since we are trying to keep things as close to natural as possible, even if your not running ZEO. I really never used to test much but my tanks have also never looked nearly as good as some of the ZEOvit tanks I am seeing.
