testing

I have been cycling tanks, both saltwater, and freshwater, and had never seen this happening. I have been cycling a new system for a few weeks now. I have been using Dr. Tim's ammonia chloride solution. Every time ammonia falls below 1 mg/L I add some more to get the concentration around 2. I...

At what point in the 4 month cycle of a new saltwater tank should I start testing & adjusting the Calcium & Alkalinity? Is it best to start immediate when you initially set up the tank? Or a few months down the road when a few fish are already living in the tank & I want to introduce coral?

Hey all, I’m 22 days through my cycle currently, and am experiencing ridiculously high nitrites, so high my Red Sea kit can’t read them properly. I seeded with Dr Tim's one and only, and am testing with all Red Sea test kits. My ammonia has started to drop, nitrites have soared, and nitrate is...

Just got some new hanna checkers today and tested high range nitrate. The result was too high to read, and the instructions say to dilute it if that happens. I cut the sample in half and added more water, same result. After a second halving I got 52! This result seems ridiculous as I'd expect...

I just got my results back. I took my sample the same week that I started a chaeto reactor so know my nitrates and phosphates will come down, but am concerned that my nitrates are 135x my phosphates instead of about 10x like I see being ideal. I’m thinking of starting to dose NoPox but am unsure...

Hello fellow saltines, This is my first time doing a magnesium test. I bought the Salifert test kit. There are no coral in the tank yet and I don't do any dosing. There are a couple fish and at some point I want to keep softies. The test gave me 1200 ppm. Should I raise this with dosing if I...

So I’m new to the reefing chemistry but I just tested my water and these are the results I got. Are they good and what’s the level they are supposed to be at? *Syringe tips are over the results I got

I recently purchased a 65 gallon Red Sea aquarium on Offerup. I currently have a 32 gallon Biocube stocked with 4 fish and I am planning on transferring these fish into the new tank. However, the nitrates in this new tank are fairly higher than my Biocube (40 ppm versus 10 ppm). Is this too big...

I made a large water change today, and thought'd it be "fun" to compare results between the new Hanna Nitrate High Range 782, and the old Low Range 781 using the dilution step. 781 Low Range diluted 782 High Range Percentual Difference Before Water Change 24,9 33 27,9% After Water Change...

i’ve been in the hobby for a while but have never touched a calcium reactor do i test more regularly for my calcium and alk or not?

I know I ALWAYS have a little ‘test anxiety’ when performing my water tests every week (alk every other day). I always hope everything turns out well and it usually does. Problem is, when it doesn’t (or I have missed a few weeks of testing), it can sometimes bring on a little panic as the...

I have been consistently getting 0 on Nitrate and Phosphate. I have chaeto in a back chamber that’s literally doubling in size in about a weeks time. I give it 18 hours of light which I’d read was recommended. I also have green hair algae forming on the sand. As of yesterday, my ammonia level...

So I’m confused and need some help I have a mixed reef tank softies/lps and I have been testing my alkalinity each day for 7 days to try and figure out how much to dose each day, I am using the Hanna alkalinity checker so it’s pretty accurate, my problem is it’s staying the same I have no drop...

Hello, I was gifted a well-established reef tank back in december (3 fish, some soft coral and a war coral), and I've been trying to learn as much as I can about the hobby to try and keep everyone alive. I bought the red sea marine care and fundamentals multi-test kits, and neither of them have...

Is this even possible? I have a discrepancy that I'm trying to wrap my head around. I did an ATI ICP and got my results back. It says my salinity is 45.69 psu. My IceCap digital, calibrated with 35ppt, reads my SpG at 1.022 My fish are fine, my soft corals and some acans, candycane are...

I have a, used twice par meter. Pretty much new. Original packaging Selling for what I bought it for $357 Comes with wand. Shipping included.

Today I came across a YouTube video... I know,I know, don’t trust YouTube vids. And that is why I’m here asking. The video claimed you really only need to test Temp, Salinity, and PH. What are your opinions on the top, or most important parameters to test?

I'm not sure if this the appropriate forum for this, but oh well. Has anyone had experience with this test kit? I'm wondering if I'm just unlucky or the equipment in this test kit is just junk. I've had this kit for about a month now testing DKH every day. I've noticed the markings on the...

Like new digital Refractometer, comes with original box and RODI/sea water standard samples for calibration. Works flawlessly just no longer need it as I’m no longer in the hobby. Asking $105 shipped.

I'm a bit overwhelmed by the number of Hanna Checker for phosphate. I've opened a poll to see which one you guys use. Could someone correct me if my understanding of these three checkers is wrong? And maybe suggest which one I should get? The HI774 sounds like the best choice for someone who...

Went to my LFS about 2 weeks ago. Ammonia read 0 pmm. Nitrites read .50 ppm. Nitrates read 0 ppm. My LFS advised to start dosing Seachem Stability. They advised me to do once dose and . let it go a week and currently my readings are: Ammonia: 1.0 ppm Nitrite: 1.0 ppm Nitrate: 10 ppm Is this...
