hanna

Looking for some Hanna checkers for my little nano reef adventure which has required tedious testing, and these salifert chemistry experiments aren’t any fun when I am doing them basically after every feeding! Plus my chalice are loosing tissue and I thinks it’s due to swings in alkalinity and...

I have several Hanna checkers that I’m parting with. All of them have 1/2 to all most full regents except Alkalinity. All in working order. $200 of the lot plus shipping or $40 a piece plus shipping. I would rather sell them all as one so I can make one trip to ship. Alkalinity Copper HR...

Hello fellow reefers. Happy Thanksgiving to all here! The ask: I am seeking advice on adding a new equipment (not a refugium) in my filtration arsenal. Based on my small research, a biopellet reactor in sump (just in front of my protein skimmer) would work in my situation to bring down...

Great PH tester. I am breaking down my setup and have no need for any of this anymore. I have one of the two buffering solutions required to recalibrate. I last used it a month ago and it was dead on so I don't think it need a recalibration but if I were to buy something from here I would want...

Been using a Hanna pH checker for over a year and have regularly been getting readings of 8.6+ (8.6 flashing on screen). If I put 20-30 mL (have a 20g nano) of some white vinegar in the tank, usually will bring the reading down to 8.3 or 8.2. However, recently got the Apex A3 Pro and have had...

Hey everyone! A bit of a newbie question here from someone that’s been in the hobby a long time. I’ve always just done consistent water changes, kept watch, month long cycle period, and have always had decent luck. I just set up a Fluval Evo 13.5 and want to make it a heavily concentrated reef...

Hanna Salinity Tester HI98319 - comes with 2 packa of calibrations packets. - $50 shipped to lower 48 states, no PO or APO.

Looking to buy the Hanna Phosphate ULR and nitrate testers, and might also be interested in a package deal if anyone is trying to offload them. Shipping would be to 39531. Let me know what you have!

I used the tester a few times and, with proper care and calibration, it works great. However, I was given a hydrometer as a gift and have switched to using that so no longer need the digital tester. This also comes with about 25 salinity calibration solutions.

Hello All, I have a brand new unopened Hanna Magnesium Test Kit. I ordered about a week ago from BRS. I accidentally ordered two of the same kit. BRS has them listed for $64. I'll ship to your door for $50 or possible trade for other reef related items. Thanks!

Almost Brand New Just needs new reagent, then its good to go. I just switched to Salifert as it’s easier to use and more accurate $40 pickup $45 Shipped 19114

The weirdest thing has been going on while testing. So I have the hanna phosphorus ULR and the Phosphate readers. So I know they have a conversion chart for the phosphorus and for some reason I had a 200 plus ppb reading last night. So i was like no way something happened while testing. I said...
