calcium

I have a 44 pound box of large reborn and I have all the other stuff that I have normally mixed in it for years, and I’ve had wonderful success. It’s a blend of others and size. It’s all in the pictures and it’s probably $300 -350 worth of media.

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...

Hey everyone, I’m trying to wrap my head around why has my Alk risen and whats depleting calcium and magnesium. And what’s the solution. I recently added a hammer garden (9 heads) and a yumma mushroom and soon after I noticed my Alk jumped to 10 and resulting in depletion of my calcium and...

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 My friends, i have a 105gallon Reef tank just lps, zoas and softies. I’ve been dosing 22ml of all for reef daily for about 9 months, alkalinity has always been stable my issue is calcium, it’s always been high im thinking of ditching all for reef and going to a regular 2-part any thoughts...

Everyone knows one of the keys to successful coral growth is stable Alk/Ca. My question is, what is the real definition of stable? Are we talking about a rock solid unwavering alk of 9.5? or is bouncing around from 9 to 9.5 back to 9.2 , etc. ok? Here's my trident results from the last few...

Something strange is happening with my Red Sea Calcium Test kit. When I drop in the powder, some of it turns to little stones. And I’m guessing it is messing up the result since some of the powder is not dissolving. I bought the kit new less than one year ago. I follow the directions precisely...

Hi all - trying to figure out what's happening with my water chemistry. I am fairly new at reefing and upgraded from a 40 DT nano to a 110 DT (525 Red Sea) about a month ago. Question I have is what would cause a significant decline in calcium from 410 ppm on 11/28 to 320 ppm on 12/12? Here...

So for a few weeks now my calcium has tested at 280-310 which I obviously would like to get up to closer to the 400-450 range. The only thing is my alkalinity has been fine at a steady 8.2. Is there a good way I can raise my calcium without it affecting my alkalinity?

Hey there, I've recently increased my tank pH and kH by using Soda Ash. I've noticed a significant drop in Calcium (from 500ppm to 155ppm). I understand that it's due to precipitation, but I don't fully understand why Strontium has dropped too... Despite being dosed, it went down to 2ppm while...

Hi there, I just checked my parameters and my alk and calcium are both very low: Alk ~5 dKH Calc ~350 I measured both with Hanna Checker. I ordered some all-for-reef to get into dosing but can I also just add a bit more the first several days to get around 8 dKH en 450 calc? After I get to that...

Hello, I would like to keep my macros on levels similar to Red Sea Coral Pro Salt (Ca 465, Mg 1390, kH 12) + raising pH to levels between 8.2-8.5 depending on the timeframe. Of course such levels significantly increase precipitation of minerals such as calcium. What can be done to prevent it...
