Hey folks, So, the Salfert Nitrate test offers two ways to read the results. Hold it up and look through the sides of the vile/container, and get a 1:10 reading, OR look down on it through the base of the container and get a 1:1 reading. I would have assumed that if I checked both, then I’d...

Looking for some Hanna checkers, because they are SOOO much cheaper second hand. Looking for a salinity tester, alk (dkh), phosphate (ulr), nitrate (HR), ph, calcium and a magnesium checker/tester. So pretty much all of them! :rolling-on-the-floor-laughing: Please take my money and save me a few...

Like new condition including the boxes. Purchased earlier this year. Factory reset, properly shutdown via tasks and ready to go. Prices include shipping in the USA. Apex SOLD

Unfortunately I am going to have to let go of some things due to a family tragedy. This is new in the box, and only under rare circumstances am I willing to ship (mainly because there seems to be an occasional issue with people paying), and only if the buyer is willing to use Zelle. I live in NE...

Selling my ITC Par Meter. Works great, just don’t need it any longer. Free shipping!

Hi, I'm still fairly new to the hobby, I've only been running my tank a few months. We installed a Trident about a week ago and it showed our Calcium was too high, way up at about 576. I think we'd been misreading our Red Sea test kits and over-dosing as a result. Since then Calcium has slowly...

Quick question…….how many days do you test Alk before making a call on consumption? Test daily and at same time? Better to test at certain Ph levels? So morning or afternoon or night depending on Ph levels? ‘ I’m asking cuz I think my tank is consuming roughly 10 ML a day…I get it to 8.3 then...

I am just wondering because I think MicroBacter CLEAN tries to do the same thing that Vibrant did. I could be wrong was just curious.

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...

Neptune Trident up for grabs. Just recently service for maintenance at neptune (have receipt for proof of maintenance). Used for approximately just over a year.

Both logically and scientifically I realize that that calcium levels in my tank should not be rising unless I'm physically adding calcium to my tank. According to my Trident (recently calibrated), a hanna checker, an aquaforest test kit, and my LFS.... my calcium levels are continuing to rise...

Hello! Ive just done some testing since coming back from vacation. The tank looks good, lots of growth, but we lost a large invert without specific cause and I wanted to see where things were. We run a higher nitrate tank typically, fyi. I’m aware that I need to add fresh h20 and add calcium...
