Hanna Nitrate and Phosphate testers. Used once. They overkill for my tank. My loss your gain. $100 for both shipped

These might help in understanding

What do all algae (and cyano too) need to survive? Nutrients. What are nutrients? Ammonia/ammonium, nitrite, nitrate, phosphate and urea are the major ones. Which ones cause most of the algae in your tank? These same ones. Why can't you just remove these nutrients and eliminate all the algae in...

Hi Everyone - I'm new here and have been lurking for a while, but finally am experiencing something for which I could use some tailored advice. Would appreciate thoughts from anyone. Background: I ran a fishless cycle over the course of a month in late December / January. The tank completely...

I had a massive dinoflagellate outbreak in the past few months, and took the necessary steps to fight it off. I dosed PNS pro bio's purple non sulfuric bacteria, dosing 150 ml daily until I killed the bottle. Fed my cope pods reef nutrition's phyto feast and they've exploded in population ever...

Hey fellow reefers, I have a 20-gallon long tank that’s been running since 2021, and I’ve been having trouble getting any phosphate readings lately. I’ve been tracking my parameters daily for a week now and dosing nitrate, magnesium, and phosphate (all Brightwell Aquatics products). That’s...

Hello all and let me say thanks in advance to those willing to give some advice. A few months ago I noticed all the euphyllia in my tank starting to look worse, not fully extending, almost a shriveled/ withered appearance at that point I started checking everything and noticed that my phosphates...

Some background on the tank: I bought this system (rock, water, and livestock included) about 5 months ago. The tank had already been running for over a year before I got it. I don’t know what phosphate levels looked like when I first acquired it, since I didn’t yet own a Hanna ULR checker. On...

Hi All! I recently got back from vacation and some of my mushrooms and RBTA were not looking the greatest. All my xenias, gsp, and zoas look great, but I was worried about the mushrooms and RBTA. I checked my phosphate using the Hanna ULR checker and it told me 0.43 ppm. From what I’ve read...

Hi all, I have 75 gallon that I made a post about about 3 months ago I was battling GHA, luckily 90% of it is gone at this point but I am now facing cyanobacteria. I think the cause of this was when fighting GHA I had really high phosphates and nitrates which I still do just little bit lowered...

I have a Hanna Phosphate ppm and a Phosphorous ULR ppm. Two boxes of reagents good through 10/2026 for the Phosphorous ULR. No reagents for the Phosphate. Asking $50 Shipped for the pair

These are the results from today, same as it was the last time I tested 1.5 years ago. Is there really a benefit to testing these parameters weekly or monthly if I keep getting the same results every time?

Hello all, I started with a 17 gallon tank and did not need much testing as it was mainly a Fowler. I now have 3 GSP and a red mushroom/ leather? What should I be testing for with these? As well I am starting my 210 and hoping to put corals and fish in around June/ July. In this I’m mainly...

Hello and happy weekend. I've had a reef tank, or have been trying to successfully get one up and running for a year now. It has been in operation in that time but it had a little good and an extended bad period. I'll give a history but then I'd like to get to solving the current problem because...

All three meters are in excellent condition—clean optics, no scratches, no salt creep. Stored dry. What’s included • HI780 Marine pH Checker – two cuvettes, caps, battery, full bottle of the reagent • HI713 Phosphate LR Checker – same accessories + ~6 reagent packets • HI783 Marine Magnesium...

I am trying to keep phosphates stable in my tank. I constantly have zero phosphates unless I dose some sort of phosphates. I have been dosing 6ml(0.02ppm) of NeoPhos daily and it still test at 0.00 daily. Once it read 0.01 but back to zero the next day. I test using the Hanna ULR phosphate...

Would you say this is 1 or 0.5? Is this too high for a new 20 gallon aquarium? I’ve had 2 clownfish and 4 soft corals for 1 week.

I am hoping that someone here might be familiar with the Aqua Medic Platinum Line Plus RO system as I am having some issues with its ability to actually filter my water. After replacing the membrane and resin, and flushing for two hours, my TDS is flashing 99. The system is one I took over...

Hey Guys, should start by saying i have recently upgraded my tank to a Cade Reefer 1200 This is my first time having a full sump system aquarium previously running my tanks off canister filters Having a few issues with the new tank i was hoping to get advise on, with the return pump i was...

Hi, My sump has a refugium and filter socks. Currently, the tank is doing well, but I hate changing and cleaning the filter socks. I recently tried using filter floss, but I noticed that my glass gets dirty much quicker and the phosphate climbed up. So, I'm thinking of installing a roller...

Hi, I was wondering if anyone could recommend a reference solution for nitrate and phosphate to verify my Hanna and Trident NP tester. I know Fauna Marin used to have a seawater reference product but I think it might be discontinued as It says it is out of stock at all the retailers I use. I...

$25. Comes with a few reagents. Used it about 5 times, bought in Jan 2025

Hi all, I would like to get your advice about rebooting or not a tank. Mine is 50g that is 1.5 yr old. I started it with dead rock that I boosted with startup bacteria. It had a long nitrite cycle then was all fine. I used to have very tiny patches of dino/cyano/hair (not that expert to...

I've been using the reef-factory smart tester to test the phosphate levels in my tank for ~3 weeks now and like to report my experience with the tester. My tank is a IM 100EXT with the RFS sump. It's currently a low nutrient setup. Total water volume estimated to be around 110 gallons based on...

I'm having trouble with my sandbed, which is leaching phosphates and KH. Some people have suggested that I remove the sand, but I'm a bit concerned about this. Currently, there is no sand stock left in my country, so for now, I can only remove it, not replace it. Current Parameters...
