calcium

Hey there, Following @Randy Holmes-Farley advice and BRS videos, I am keen on trying Kalkwasser as the key source of Ca, Alkalinity and pH increase. The primary reason is the fact that it is supposedly straightforward followed by lack of additional NaCl accumulation which would require...

Hello, First of all - thanks Randy for your contribution to spreading knowledge on this forum. Without you I wouldn't learn many things I have never heard about it, despite the fact I do not like going with the easiest and most common solution and thus I like to explore and experiment. I...

I’ve been in the reef game for a long time, but took a break for a while and just recently got started again. This time around I’m trying to make sure I really stay on top of water parameters, so I’ve been testing regularly. I started this time with a used tank from my dad, a Red Sea 350 and re...

Brand new never used Hanna calcium checker. Only selling due to having to shut down my tank to go to college. Asking $45 shipped but willing to haggle

Hello, I am having a weird problem. My calcium won't go down. I have been using tropic Marin all for reef for quite some time (powder mixed with RODI), and recently I've noticed my alk and mag are ok (9dkh, 1375 mag) but my calcium is 550-600 (usually 430-460). I lowered my all for reef dosing...

Hello guys, I’ve got a question regarding aquaforest calcium. They say to dissolve in 1L water and dose 100ml per 100L of tank water. Well my tank is 100L and me adding 100ml of water a day to raise the calcium by 18 is gonna make my tank overflow lol. They say you can make it concentrated so...

I'm sorry to ask this if it's stupid ☹️ but I really need help in how to use these...I tried and by the end I'm so frustrated because I don't understand and also I have a disability with numbers so this makes it harder ☹️

I have a 6 month old 65 gal mixed reef that I’ve been dosing with all for reef. I use the powdered form and mix it myself. Currently have mostly small lps frags but a handful of sps and softies as well. I’m waiting for my parameters to get more in line before adding in any more acros. Most of...

Hi, Today did some testing and I found that my alkalinity is pretty low. dKH: ~6 Ca: 470 Mg: 1440 Salinity: 1.025 pH: ~8 Nitrate: ~6 Ammonia and nitrite: 0 These testing results are 1 week after a water change. I use Tropic Marin Pro salt and a new batch of water has around 7,2 dKH. Should I...

Hello, I need a bit of help with the salifert calcium test. I can’t work out what the result is. I added in pretty much all of the Ca-2 until the water turned blue. I have attached a picture of how much I added and the blue water.

So I have my apex trident testing and I will post an image of my results for you guys. My alkalinity has been sitting at 6.28. My apex has been saying it is usually at that measurement for the last month or so, ever since I set up the trident. But I just did a test with my Hannah tester and it...

Hi Guys, I've been testing my tank water for about a week and have recently introduced my first batch of coral - 4 small LPS frags along with a small Zoa frag into my tank this weekend. In the week leading up, I was told my Calcium was low by my LFS after I took my water in double check my...

I’ve been running a 32 gal AIO reef tank for about a year (with a lid). The Ca constantly runs high (500 to 550 range). This is meassured 2x per day on a Triton and have verified with a Salifert kit. I was using Tropic Marin pro salt which runs high on Ca but bumped down to the regular version...

My calcium is at 361 ppm and alk is at 8.1 dkh, these are currently the only Hannah checkers I own and don’t have a phosphate reader and I know most people don’t like API but it’s currently what I have till I can get mor checkers. Waiting for a sale but ph is a little above 8 from the color...

Hello all, As the title says I just got back into saltwater after about 10 years. This algae whatever it is is winning the battle because I am out out idea's my water parameters are near perfect though about a week ago I added some calcium supplement (for my halimeda plant) and misread the...

Hey everyone, so I’m trying to stabilize my parameters and get a good dosing schedule going but my calcium keeps rising and my alk keeps dropping pretty fast. I know that they are connected and that’s why that’s happening. My alk is currently around 10 dKH and my calcium 501ppm (trident system...

So about a week ago i began dosing kalkwasser into my tank through my ATO to try to raise my alkalinity and calcium given they were both reading lower than usual. My alkalinity has increased by .2 already which is good except the kalkwasser mix seems to be making my water cloudy. I am running a...

Just getting back in so not sure if to spend on the Hanna checkers for calc alk mag and phos or purchase something else like red sea or api or any other out there now

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?

I have a 7 month old ~3g reef tank containing a faviitees, stone pipe coral, GSP, palythoa, and hydnophora + clean up crew (1 Scarlett hermit crab, 2 blue legged hermit crabs, 5 bumblebee snails and 1 tuxedo urchin). Ever since I’ve started testing calcium, my Hanna reader shows that my calcium...

Hi, so I’ve been using kalkwasser in my 150g mixed reef for the last five years. My alk is very low at 5.2dkh. calcium is 470 and mag is 1500. I started dosing ESV alkalinity to get the alk up. So my question - is there any reason i can’t doses ESV for alk and continue to dose kalkwasser...

Hey, I am trying to figure out what this stuff is on the sand bed, I was told its a buildup of calcium, so I got something to deal with the buildup, did a few water changes and its still coming back. Am i doing something wrong, or should i do more water changes to get rid of it? It seems...

Hi all im need to reefing and have limited knowledge and know chemistry and water parameters work but i get the gist of it. background: information about my tank. Tank Size: 45 Gallon (running for 9 months) Salt mix tropic marine pro reef salt (weekly 12% water change @ 1.025 salinity) my...
