I want to get some Hanna Chekers as I have heard they are quite good, any suggestions on the best ones & other tests that will be better for other tests. Currently using API like a noobie and I absolutely hate it because I can never figure out which color is which.

I have been having a few issues with my phosphate level, or I think I have anyway. Both of these test were done at the same time the only difference is that one was done with 16ml of ro water and 1ml of tank water and the other was done with 17ml of tank water. But they both have me the same...

Hi R2R Community! My FIRST POLL! Some quick background: I’m a numbers and data guy so I love it when people post polls and give feedback. I can’t tell you how many purchases in this hobby because of that. This morning while testing nitrates I was having trouble finding the right color to match...

Hey guys, i hope ive posted to the correct place, im new to the forum so thanks for having me :) im looking forward to getting to talk to others who have the same interest as me! im about to be setting up a little fluval evo mixed reef after being out of the hobby for a couple years and some...

Hi, I’m wondering if 490ppm and 9.6 dkh is bad or good? Do I need to try and lower my calcium? Also how do I maintain my alk level at 9.6.

I’m having a bit of a head scratching moment I’ve tested my alkalinity and with 3 test kits and are all receiving different numbers... I’ve just purchased two new test kits Hanna Alkalinity Checker and it tested 194ppm Which is 10.8 It confuses me since the I just bought a new Salifert...

Hello, I have a 100L fish tank with one vagabond butterflyfish and one Picasso triggerfish. I have had these fish for about 1 and a half weeks now, and I suddenly recognised their behavior to be a bit abnormal. It was just today when I woke up, the trigger was breathing really heavily and...

OK, so it's water test day... Wondering what you all make of these numbers (keep in mind we did all tests twice, just to be sure). My biggest issue is Alkalinity. We're going to retest today after we recalibrate our KH Director to see if it ends up closer to our Hanna tester. Which ones do we...

Just finished a bottle of alkalinity reagent on my Hanna tester - alk reads 11.8. Open the new bottle and re-test to check consistency. 10.7 ... Run a third test (from new bottle), confirms 10.7! The previous bottle is still well in date, has been open for approx. 4 months. Confident my testing...

For what its worth, I thought I'd share a comparison of my test kit result vs those given back to me by Triton. Notes: - I took my sample test kits within 1 hour of the same time I collected my water that was sent into Triton. - I shipped out my Triton sample on 1/14/2020 and received...

Question: If you own a Trident, do you still perform manual tests with the test kits that you used prior to acquiring a Trident, such as Salifert, Hanna, Red Sea, et al. Why do you, or do you not, perform manual tests? I tried searching for threads that involve discussions about whether Trident...

Hi all, nearing the end of the cycle on a new tank. I have a Hanna Nitrite ULR tester that to-date won't give a reading as every test reports '200' (out of 0-200 ppb range). My Red Sea Nitrite tests are coming in between 0.5 and 1 ppt. I believe I should trust the Hanna (non)reading, but that's...

I know...I have a problem. I was organizing my supply cabinet and realized I have clearly accumulated more test kits than should ever be necessary. BUT it has been helpful having everything I need at arms reach, and the ease of use of these kits has caused me to test consistently, which I’m...

Hey all, i tested my water last night and tonight to see the amount i need to dose for calcium, alk, and magnesium. Last night, my alk was at a 7.2, magnesium was around 1425 ppm, and calcium was at about 520 ppm (This was after a water change that I did a day before). Tonight, I saw that my alk...

I technically didnt do water changes on my tank for 3 months(i did but only twice) cause i ran out of salt and didnt buy a new bucket cause i was thinking of switching salts idk why it took me so long. But well yea ive...

I have the API master saltwater test kit that expired in 2015. I know a new test kit is only about $30 but what are your thoughts and experiences on using an expired API test kits? What makes a test kit expire?

What? Every 10ml syringe I have, will fill about 1/8th" to 3/16" above the cuvette line (depending on how the water curves up in the cuvette) which is supposed to be 10ml. I've used 4 different syringes. Frankly, google searching "Hanna 10ml line not really 10ml" lead me to several pages of...

Tank and stand are up! Rockscape is, I THINK, finally in its place lol and equipment is ready. RODI is filling up as we speak. But now here is my slight dielema, I bought the API master test kit, not the one for reef as I’m not including corals just yet. But I’m now reading and hearing some...
