I have 4 Hanna Checkers for sale. I have had them for a few months and I don’t use them as much as I thought I would in favor of going to the fish store to get my water tested. They were all used a few times but have all parts including the boxes and some have the sleeves. They are $50 each...

Hey, running the seneye for temp and ph monitoring, its showing a super low PH (6.4). Surely that can’t be right, is this a misread ? i double checked with a crappy API kit and it tests fairly normal ,at least a 7.8 ? any insight would be helpful. thanks

I tested my marine tank for phosphate using an API Reef Master Test Kit and found a concentration of 0.50 ppm. Curious as to why it was so high, I prepared a gallon of saltwater from Fritz Aquatics Reef Pro Mix and found a concentration of 0.25-0.50 ppm. I tested the RO water from which it was...

I asked Neptune about my trident being off from other test kits and they told me I have to test the test kits to the calibration solution that is provided by Neptune in the trident dosing solution to compare how off they are to one another. this seems very logical and a way to calibrate your...

I have noticed my API kit readings are always much different than my RedSea. Any advise on which I should be following or do I assume my numbers are somewhere in the middle? Is there another test kit I should be using? For example, PH - API 7.8 vs RedSea 8.1 KH - API 10 vs RedSea 8 PO4 - API...

This is the refresh of my original 3D Printed Test Kit Organizer Tray thread. The first post showcased now-old designs and one had to dig through the thread to find the new stuff, so a new thread was made to clean things up a bit as the old cannot be edited (Old thread will be deleted/closed by...

I have just been testing my tank for nitrate and I am now not sure which test I should trust. I have used a red sea and a salifert kit, the red sea kit said I have Nitrate of 36 ppm and the salifert said 2.5 ppm. Everything else in the tank is testing fine just the nitrate test that is the...

Has anyone had any experience with the aquarium systems seatest test kits? any reviews/experiences? cant find anything on them, my LFS recommended them but im getting "odd" or just unexpected readings and dont know if i 100% trust them yet. Im using the ammonia, nitrite and nitrate test kits of...

Hey all! I have a 13.5 EVO tank. It is going on 7 days old now. I have tested the water and specific gravity every day. Before getting into the specs, let me tell you what is in there: Livestock: Caribbean Live Sand Roughly 10 lbs of aquacultured live rock (red algae and bristle worms living...

Iv seen online that the NT Aquarium Lab kit is a whole lot cheaper than the marine version and includes more testing liquids. Are these just the same tests but differently priced to make more money from mariners? Or am I just better off getting the marine versions? Currently been using API and...

Hello Everyone! So past couple of week ive been having problems measuring the daily dosage for my Mg, Ca, Alk. I was using salifert for all three and i would adjust all three to the recommended level then wait 4 days then remesure them, but i performed this 3 times all over and all three times...

I have a 36 nano reef that’s about 5 - 6 months old. Every time I test it says my parameters are perfect. I don’t believe that is accurate because I have had 2 fish die this week, although my coral are looking healthy. I’m using the API test kit, but looking for a new one. What would y’all...

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...
