FYI: dolomite & "magnesium carbonate"

Hector, I am guessing it increases salinity if you are using magnesium chloride additives... as opposed to Epsom salt (magnesium sulphate)...

Or maybe not, I'll have to read up on it.
 
Randy F-H says long term sulfate buildup is no bueno and recommends a blend of magnesium chloride and magnesium sulfate: 5 cups mag chloride and 3 cups of mag sulfate per gallon of supplement. That's also the quantity and ratio recommended by BRS with their additives.

As far as Kent M and bryopsis go, I achieved great success reducing bryopsis by using elevated levels of magnesium (1500-1800) from a dyi mag mix high in mag chloride. No Kent M. I believe it is the mag chloride that is the active bryopsis reducer. As this thread demonstrates, most people dose only mag sulfate (Epsom salts) and thus see no bryopsis reduction with elevated magnesium.
 
My understanding with salinity creep is that is primarily due to free ions from the A and B parts. A (typically sodium bicarbonate, NaHC03 or sodium carbonate Na2Co3) provides sodium while B (calcium chloride, CaCl2) makes chlorine available. Those combine to form sodium chloride (salt, NaCl), and up your salinity creeps.
 
I have recently bought two of the large bottles of techm to combat that pain of an algae briopsis. No matter what else I do I can't shake that stuff in a few patches in the DT.

So you guys have had succes just raising mag with the mag chloride? I know BRS has it as we'll as ebay sells it in food grade but I think I'd be more comfortable buying it from BRS for some reason :). Good to know if this tech m doesn't work or I don't have enough?

Did most shoot for the high 1700-1800 like recommend or lower? And was it just kept there for a few weeks? How long did the elevated levels have to be kept to clear it up?

That cheap captain America frag turned out to be not so cheap lol.. FYI H202 doesn't solve briopsis long term more like a few weeks tops IME.
 
You can buy mag chloride as mag flake in a 50lb bag. Ill have to look into where, there is a local chemical distributer here. That is where I got my Dow flake, calcium chloride. It they carry it I am more then happy to go in on a bag people.
 
Yes what I gave you is Epsom salt.

I will check out the Chem company here and see if they carry mag flake. If not ill look around and see if I can find a good deal.
 
"I achieved great success reducing bryopsis by using elevated levels of magnesium (1500-1800) from a dyi mag mix high in mag chloride."

Reef Bass do you mind saying what you ratio was that you used?
 
It was a couple years ago, but I believe it was straight mag chloride. I wasn't looking for a long term ideal ratio, just short term "nuke the bryopsis". Once the bryopsis thinned I went back to 5 : 3 mag chloride : mag sulfate and allowed my mag level to drop back down to 1300.
 
Thanks that what i am looking for also. Short term to kill the bryopsis. I will go with strait Mag Chloride and post back with the results
 
So this mix of mag chloride and mag sulfate is used to maintain magnesium and calcium chloride is for calcium and alkalinity? Are these dripped simultaneously?
 
Edit;didn't see the post about straight mix ;)


I've been having an issue with a few spots and I'd rather use this than so much tech M if it was successful for you..

Read the article that lokii posted. It talks about two part (aka 3-part if you dose magnesium).

Calcium chloride is used to adjust calcium.

Sodium bicarbonate or sodium carbonate is used to adjust alkalinity.
