magnesium

Hello Reefers, I have a 20g long tank and I'm loving it, my tank has been up and running since February of 2021. I've lost about three corals, a sand sifting star, three fish, and two emerald crabs since the start of my tank. I'm afraid I'm going to lose more of my corals, because of gha and...

Marine Ammonia Marine Calcium Marine Alkalinity I also have a sweet 3D printed holder/stand

We have a 75 gallon tank with a Fluval 407 cannister filter. Bottom tray-black sponge followed by polyfill, Second tray- Chemi-pure & polyfill. Third level- biomedia. Final tray- ZeoCarb & phosphate remover pads Return line has a fluval spray bar, the Inlet has a Fluval skimmer with midline...

What do you guys use for a magnesium powder solution? ive tried Redsea magnesium powder solution but it leaves a residue. what else is out there’s that’s good on the wallet also?

I am new to Saltwater. I do not have any corals. I have 2 clownfish. Redsea reefer 425. I keep putting in Alkalinity, Cal, and MG thru apex DOS. The levels keep dropping. I do an automatic water change of 1.5 gals every day. I use Classic Sea Salt Mix. Alkalinity - 9-10 dKH (approx) Calcium...

System Volume: 20 Gallons Alk: 8.8 Calc: 400 Mg: 1080-980 PH: 8.2 -Mg consumption of ~50ppm a day -Daily dosing 80ml of 460g/L solution -All other parameters stable. -Upping to 100mL/day Help!

I bought all of my test kits new in November and my Salifert test kit for Magnesium has consistently tested low from the first day I started using it (~1,020-1,160). At first, I thought the issue might be that I hadn't shaken up the bag of salt (Reef Crystals) and the minerals were unevenly...

Does anyone have any knowledge as to whether or not Red Sea Trace Colors A/B/C/D affect magnesium? I don't see it listed on the insert that comes with any of them, but since stopping water changes and dosing these trace elements, BRS calcium chloride, and BRS Soda Ash over the last 4 months my...

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...

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 am dosing iquatics kh buffer daily (0.3g) to maintain kh 8.4 Whilst calcium stays steady at 420-400, magnesium is dropping. I am dosing magnesium salt every day to maintain at 1360. Without this it falls to around 1200. Even a water change will lower it to 1290. salt params are way higher...

I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...

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...

So this is my first time posting as I can usually find all of the answers i’m looking for in threads but i have something very puzzling going on. My Mag levels are rapidly depleting without any major changes in other perameters. I waited until i had 5 tests one week apart each with a 10% water...

I picked up one of the new Hanna HI783 Magnesium checkers when they dropped last week, and after one or two mulligans I got it working pretty well. A little more complex than the basic hanna tests (requires 2 reagents) but nothing too bad, especially vs the other titration mag methods. The...

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...

So I have not dosed any Mg in the last month and a half, all the products I use to maintain the tank does not contain Mg. Anyone experience something similar before? Kh is being consumed at around 0.5 every 4-5 days. Corals are medium load 95% softies 38 gallon. APR Mg 2 3 1350ppm 5...

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...

Hi all, I have hair algae in my 255L LPS tank. It's kind of green and brown. The tank is about 2 months old. I have one blue tang and one lawnmower blenny but seems both of them are not interested in hair algae. I also have one ocellaris clown fish, one flame hawkfish, one conch, one turbo...

Hello fellow saltines, This is my first time doing a magnesium test. I bought the Salifert test kit. There are no coral in the tank yet and I don't do any dosing. There are a couple fish and at some point I want to keep softies. The test gave me 1200 ppm. Should I raise this with dosing if I...

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

I'm a relative newbie to dosing and I'm trying to educate myself as much as I can but with limited time to read up on it, I can't make an informed decision on my own right now. I've been dosing with baked baking soda and calcium chloride but I'd like to try Tropic Marin's Carbocalcium because it...

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...
