testing

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...

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...

Hi all I am new to the hobby. I started my fishless cycle on the 1st of December. I added dry reef, coral sand, decor (I believe resin; LFS said it is safe for saltwater tanks), a heater, a wave maker, and a filter with an active carbon filter. I filled the tank with RODI saltwater I bought...

Hi All, I`ve been in the hobby a while now. I have had good success with Softies and LPS but when it comes to SPS I just dont seem to be able to hit the sweet spot. Tank is a DD Reef-Pro 900 (290 Litres total system), I have a Radion XR15 (Blue) at 100% on the AB+ Setting, 10% water change every...

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 guys so I had a velvet out break in July and since then my tank has sat empty of fish and I plan to keep it empty until the end of September to be fully safe. But I have a question of when adding fish I don’t want to add them all at once and then they all get velvet again even though I’ve...

Don't really know where to put this. Sorry if in wrong spot. I started cycling my tank 3 days ago. I used 3 32 Oz bottles of fritz zyme 9 (needed at least 2.5 bottles but just dumped all 3) and Dr tims bottled ammonia. The bottle recommended me to use 4 drops a gallon. It also said 100 drops...

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 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...
