According to James planted tank calculator I mixed up 200 grams in 500ml water to get .1/ml. Total water volume 100 us gallons.
Questions are how many ml per day can I dose max?
In sitting at 1280 now id like to get back closer to 1400.

I like to break it in half since it takes so much darn mag to raise levels lol.
Its crazy man. According to this mix 200 ml will raise 20ppm? Something is messing with my brain.
If thats the case my other question was going to be is there a more economically efficient way to dose mag without going broke?

Or i would check out brs's magnesium.
They sell it in premeasured 1 gal bags or large bags to mix yourself. A 7lb bag is the same price as 800g of brightwell powder.

Youll never go broke dosing mag again lol.
Glad I asked. And thanks for that calculator. It doesn't match the mix or dosing for James planted tank calculator but the one you posted is designed specifically for what im using maybe that's where the discrepancy is coming in.
I think ill go with the flakes its way cheaper!
I was hoping all for reef would keep my levels correct but had my params certified today at 8.6 alk, 370 cal and 1280 mag. New tank is tearing through alk and mag super fast. Something about the higher mag my shrooms really liked.

FWIW, the rate that I'd raise magnesium depends on its purity. 25 ppm per day is a good start for materials you have not used before.

Be warned, the James planted tank calculator will underestimate the magnesium boost by close to a factor of 2 since the Brightwell product is anhydrous and the calculator is for a hydrate.
