Exact iDip Digital Water Testing

[thedru13]

I tested Saturday with the new update installed. I am going to post up my results. I tested using the idip and salifert tests. I did alk with Hanna, idip and salifert..
idip results..
570 pH PH 8.5 pH
570 pH PH 8.8 pH
570 Ammonia NH LO ppm
570 Nitrate, Marine NO3 LO ppm
570 Phosphate PO4 LO ppm
570 Calcium, Marine CA 170 ppm
570 Calcium, Marine CA 191 ppm
570 Alkalinity, Total AL 155 ppm
570 Alkalinity, Total AL 156 ppm
570 Alkalinity, Total AL 179 ppm

Salifert
Calcium - 380ppm
Alk 11.2dkh

Hanna
alk 184ppm- 10.304 dkh.

Ph Probe reads 8.39...

I was wondering if the units are the same between the Hanna and the iDip.

 

[reefwiser]

No Hanna is made by a different company totally. Now deep inside they may use the same sensor. Hobby kits can only get so close to a value. What you want is consistant and easy to use readings. With Triton now it is best to send off a sample every few months and see how your test kits are doing as far as readings. I like the iDip because it is very easy to use and it stores all my readings for me to check on them. Many days I am tired from a 12 hour day at work and I still want to test my alk I can do it easily with iDip with out a lot of counting of drops.

You didn't post a conclusion, but those values do not seem in close agreement, not even by reefing standards.

Not sure what to conclude. Just posting the raw data. I dose my tank so have been managing by the salifert tests for that. I started dosing using the idip and I have lost one frag but I can't attribute the idip to that. Could just be random.

I will keep it real I like the idip and was one of the first to get it but I have to say if they don't make it more reliable then all I did was buy a next ALK test kit cause that's the only thing that has been reliable for me from I got the idip.

 

[lnevo]

I got it for the nitrate test. Your nitrate results seem good? A digital test for that was $249 you add a reliable alk meter and you break even.

 

[Greenstreet.1]

I can hear that but I do not test no3 reg only time I test is to see if I need to add more bpellets. I really got this kit for the main test ALK cal mag po4 and no3. Not giving up on them yet

 

[akitareefer]

I just got mine in the mail today. The Alk readings compared to my other test kits (hanna, Salifert) were 30ppm or more off. All my important tests read Lo ppm, to me this is useless information. My other test kits go down to 0.00, those are the results I want to know. I really liked the concept of sending and saving data on my phone but the readings are too far off or don't tell me any information. I'll be returning it immediately.

 

[Greenstreet.1]

Well I hope they are working on making it more accurate and consistent. I'm giving them a month before I start to ask questions again they did give us an update before the end of last year as they said they would but still no update on mag. Hope they stay on top of it or they will have a lot of angry reefers.

I got to order this and use it at MACNA 2015 by far the best all in one and easiest tester available go check it out you will cut your maintenance time and free up space in the process.

New ios app update today. Says to resolve issues with derived algorithms. Not sure if it helps us with anything yet. I'll be running through a round of testing tonight

I hate it when my derived algorithms are unresolved.

 

[Greenstreet.1]

Just got it also will see what's going on tonight when I get home from work later still don't see anything on mag.

regardless all test methods have errors, if your that anal about it pop for a GC of HPLC. in industry we use photo specs for testing a lot of the same parameters and they work fine, and titrations for parameters thaqt dont have photo spec tests. and if they can keep nuclear and conventional boiler from blowing up they will work fine for a tank.

Following.. As far as we have come with technology I'm really surprised how difficult it seems to be for someone to produce a accurate, easy to use and affordable all in one electronic testing system.. I hate all the test tubes, drops, color charts and potential inaccurate readings with most of the available kits so in general I avoid testing like the plague unless I feel something is off in my tank or I need a value for dosing.. If I could insert prob in water, press button and get all my parameters (accurately) in one step I would probably be testing multiple times a day just for fun

Whats the lot number your using for the hanna alk checker? Lots have been bad. The 1dkh difference your seeing between it and salifert is a typical deviation for bad reagents.

 

[dakoop]

This sounds like a great idea with a poor execution. Tagging along hoping they figure it out

I will let you know.

I think I am done with the iDip. I was away for a few days came home and 3 of my corals are in really bad shape. I tested right before I left things were good. I tested as soon as I got home. Numbers were the same. Other testing was way different. Frustrated.

As a person who hates testing with all the drops and color charts, Im very interested in this but if test are not consistent or accurate from unit to unit / test to test, then to me its just as useless as a hydrometer (easy to use, but not accurate) hopefully they will get it ironed out by next year, after more trial and error, but im not willing to be a trial and error volunteer at this time.
