calcium

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...

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

Trying to figure out if I should be dosing/monitoring calcium and have a few questions: 1. in an LPS & fish 20g nano tank that getsbiweekly water changes - should I still consider dosing calcium? 2. What do I need to watch out for? Is dosing calcium the same as other elements like ph where too...

Hi reefers, My 50G has been doing great with just a walling hammer coral and a small mushroom frag. Hammer was doing well & I was able to replenish whatever trace elements it needed with weekly water changes. I decided to add some more coral and recently purchased a Torch and a Duncan. Since...

okay r2r got a question for everyone. I’m a fairly well versed and experienced reefer at the age of 27 currently been in the hobby for 12 years. Most everything I’ve learned (like most others) has been through trial and error and research. currently my tank is an all acro 75 gallon reef tank...

Do you guys think using Instant Ocean Sea Salt (Purple Bag) is ok to use for a yellow coral banded shrimp? Does it have enough iodine and other trace elements for it. I also have 2, 5 gallon buckets of Instant Ocean Reef Salts. I'm going to guess this one is better, but was just wondering if...

I just set up a QT, and I used IO salt. There is a light brown precipitate on the bottom. Is it safe for fish? If not should I siphon it out? From my understanding it’s a basically a hard sand, but I’m not sure if it will impact any medications like copper or metro.

Hi guys, anyone know why my calcium can be fluctuating so much?? Are these errors in the test or are they actually fluctuating this much?? My alk has been steady thanks to my doser and my mag has also been stable. I'm dosing very little amounts of calcium because my tank doesn't consume a lot of...

Hi everyone, I recently installed an apex system on my tank, I have the dosing pump as well it just hasn't been installed yet. I initially set the unit up about a week ago and I got an really low alk reading initially i think the number was 5dkh. I went ahead and started doing some brightwell...

Hi everyone, I’ve got a 2 month old 90 gallon tank that I am looking to make a reef tank, I have been stocking slowly with fish and cuc. I recently got around to purchasing alkalinity and calcium test kits and have found that my Alkalinity was at 7.9 last week and Calcium was in the 540s which I...

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...
