What would cause magnesium to deplete/precipitate quickly? I have a pico frag tank (3 gallons); and in one day, my magnesium depleted by 100ppm, while my alkalinity and calcium remained more or less within their original levels the day before. My ph is maintained at 8.2.
@bulkreef supplies, so am I correct in understanding your video in saying that it is best to get the magnesium level correct before dosing calcium & alkalinity to avoid precipitation?. As you say that magnesium hold the tank chemistry together it should be correct to say that if magnesium levels are off then one will not get the calcium & alkalinity levels up?.
Exactly! If Magnesium is too low in the water, it is likely that Calcium, and Alkalinity will precipitate out. Therefore you want to correct these levels first to account for this.
I don't understand the reason for having a different mix ratio for people who dose your two-part. I really need to order some magnesium but not sure what I need to buy.
Question? If you need a 1000 mils. of Magnesium mix according to your calculator. Are saying that you can put 500 mills in your tank over 2 days. That sounds like an awful lot.
My tank is consuming A LOT of Magnesium. It seems like a am dosing it either every day or every other day. Why is my tank consuming so much? 32 g Bio with lid removed 20 gallon sump w/ bubble maggus skimmer 300w LED 2100 g/hr of flow Significant amount of chatomorpha in sump (algae filter) Tank has been up for 1 year PH-8.3 KH-9.2 Ca-4-20 Temp.- 77-78 Mg-1280 (dosing 15 ml = 1400) Some softies.. Primarily SPS dominated Using KENT magnesium
It is less about order, and more about the time frame in between dosing. I would space the time between Alkalinity, and Calcium to avoid causing precipitate issues.
@@BRStv . Thanks. I have a 5 minute delay between all additions via my peristaltic pumps and additives are added in liquid form directy near the return pump inlet so get a very good mixing.
I seem to be using more of my RedSea Foundation C a lot more than my A & C, but I thought you go through Calcium & Alkalinity quicker than Magnesium Pls Pls Help! as I am very confused and I am now reluctant to dose and more.
Randy Holmes wrote that Magnesium Chloride would be 5cups and Magnesium Sulphate 3 cups in a Gallon of water? I am a little confused as to what way to dose?
Use Randy's method if you are using two part. If not go with BRS mix method. Randy's method has less chloride but more sulphate residue, since chloride is the residue from two part dosing and it will cause imbalance if chloride is in excess. BRS method use less sulphate since most people are afraid of increase sulphate and sulphur dioxide gas pockets.

Six years after this video and it's still amazing! - Thanks!!

I'm lost here , is magnesium a daily dose? or once you doce is every other week , I don't understand. Please help
Can I add megnesium with calcium at the same time without any issues?
Hello Dear Ryan,
how to reduce magnesium level from 1600 to 1350?
1600 is acceptable. Just let us reduce naturally over time
Is it possible to dose magnesium chloride in conjunction with kalk in an ATO?
Thanks for the info, great job
Whats the coral tolerance to magnesium flactuations? Will it have negative effect to corals if there are big changes to magnesium?

Bulk Reef Supply thank you so much for the reply.

My green montipora is looking really dull is there a reason why? could it be the lighting or lack of magnesium?calcium?alkalinity?

Which order should kg, Ca and Mg be added to the system?

What would the mix be just using magnesium sulfate only????
any plans on updating the clown harem tank? Curious to see how its progressing
Thanks for the info. Doesn't Kalkwasser have Magnesium?
Thanks! You guys are awesome. My tank comes tomorrow!
What effect does kalkwaser have on magnisium levels
Come check out my nano tank. Sorry for no narration on the video.

I have bought Magnesium Chloride and Magnesium Sulphate from Intralabs here in the UK
