Hello, I just finished all the plumbing on my new 40 gal reef tank. I wanted to test and make sure there are no leaks and since I'm not ready because I'm still searching for rock, etc.. I wanted to run a test with just water from the hose and then drain it out when done testing. Once all my...

SOLD Price dropped to $175 We've switch our system over to Trident test and since then the Hanna is no longer being used. Works perfectly. You will need to order a few of the reagents since they are mostly gone although it still has the Nitrates reagents. Asking $215 shipped

Hi all, Does anyone know what it means when the ULR Phosphate checker blinks 0.00? I’ve had a zero reading before, but never blinking.

How do you all feel about ICP testing (and now other types of lab aquarium testing, like microbiome testing and tank DNA tests)? While I could see the results as interesting, I don't really see the overall benefit/value in these types of expensive mail-away tests. Ive never bothered with one, I...

I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...

I want more than anything to have a Harlequin Shrimp.. BUT I also don't want to feed it chocolate chip starfish every other week, that could get expensive and my partner thinks chocolate chip starfish are cute, so that eliminates that option. I have been looking into other ways to feed the...

Ok, so I know this is a highly debated topic, and ultimately most people recommend both ultra low range checkers, but my question is for a newly set up tank where phosphate could easily be above the maximum range of the ultra low range checkers (0.9ppm i believe). Would it be better to get the...

If I test my freshwater bucket for PH before adding salt to raise salinity and adjust to a desired PH, then add my salt. Would I be doing the wrong thing? like how much would salinity change my PH?

The Salifert Ammonia Test is really hard to read for me between 0, <0.15, and 0.25. the readings look different in all types of lighting. Near the window it has a brownish hue to it, not deep brown, but you know... In a white lit room it can be white, yellow or brown depending which way I am...

Hi all I was just looking for a tester, one that was better than the Hanna ULR Nitrate tester and found this. Does anyone have any experience with these or anything similar? Compact Nitrate Ion Meter LAQUA Twin - NO3-11 Product code: NO3-11 Compact Nitrate Ion Meter LAQUA Twin, compact meter...

What is everyone here using to test the TDS of their RO/DI? Any tips or experiences concerning the reliability of cheap TDS pens? Would you trust a cheap HM Digital TDS-3 Handheld TDS Meter? Plenty of positive reviews, but a reviewer pointed out: The Hanna Pure Water Tester looks like a better...

Anyone have their LFS tell them that their Alkalinity and Magnesium are low and should be dosed but your own test kits are telling you otherwise? Both LFS and myself are using Salifert test kits and testing the same water sample. Alkalinity: LFS 7.85 Me 8.3 Magnesium: LFS 1290 Me 1500+

So long story short I have been having some algae issues including red (cyno) and this new hair algae (will include photos). I know my tank is never going to be clean but this is starting to take over some of my frag plugs as well as my rockscape and has started to effect my corals and their...
