test

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+

Brand new never used ended up going with a Milwaukee instead. Asking 40.00

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...

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...

Hannah Checkers (just the checkers) Alk Calc w New Box of Titrates Phosphorus ULR These do not have titrates, except for the calcium which has a new one (others are expired and trash). $130 shipped in contiguous USA. Thanks!

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...

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...

There are a bunch of models. What is the most appropriate one for monitoring phosphates at reef levels?

Hi All, I've read through leak check advice on reef2reef. Many folks seem to have many different opinions (hey what else is new ?) Some say you should leak test every time you move the tank. Some say leak testing not necessary. Some say leak testing is absolutely necessary. Some say only needed...

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...

Does anyone know the shelf life on test kits? I did a test yesterday with an API and it turned blue as soon as I added the second reagent. I measured about a 2.0. I checked again tonight and the same result. I pulled out my Hanna checker and received a 0.00. I’d love to go with the Hanna...

My water parameters are as follow Alk 9 dkh (API) calcium 380 ppm (API) Nitrate 0 ppm (API) Nitrite 0 ppm (API) ph 8.3 (API) salinity 1.024 (refractometer) i did the salifert test twice now and have been getting 140 ppm as result i bout the reef foundation products from red sea and will be...

After Marinepure was confirmed to release Aluminum by Ryan at BRS I decided to put Seachem's Matrix to the test. There's tons of great reviews out there that claim Nitrates dropped in less than a week at times. While I don't think this will be the case I decided to run my own experiment. The...

New Tank 90 Gallons. Has been running about 4 months now. I have hair algae growth everywhere. And can not figure out for the life of me why. I do all the test p04, nitrite nitrate ammonia, And everything reads 0 all my test are new and not out of date. The hair algae is on everything. Have a...

So this is my first time testing water from this tank that I've had running at my house for approximately 4 days. The person I bought it from had it running for ~1 month or so. Unfortunately my Nitrate is really high, but the pH, Ammonia and Nitrite look O.K. to me. Was wondering what you guys...
