Kent Tech M Magnesium - please check my math

[gregzz4]

I'm going to try this method to battle some algae, so ...

The bottle reads;

Add 1mL (1/4 tsp ) per gallon of aquarium capacity each day to bring the level to between 1250 and 1350 ppm.
This will raise the level by 18.3 ppm per day.

I want to raise my Mg by 100 ppm per day until I reach 1600 ppm

I have a 110g system ( total ) so ...

1 mL * 110g * ( 100 ppm / 18.3 ppm per mL = 5.46 ) = 600 mL

The bottle is telling me to add 600 mL to raise the Mg in my system by 100 ppm

Do you all agree with this ?

Seems like a lot of liquid ...

Plus, that's 1/3 of a $20 bottle

Or am I missing something so basic that I should bash my head against a brick wall for missing it

To raise up mg to that level, you do need to use alot of mg mix. but once there, it's easy to maintain. double check your salinity level when you get to 1600Ppm

Math is hard...google "Reef Chemistry Calculator FV"

It does take a lot of Tech M to raise your mag though.

Epsom Salts available at your pharmacy is a MUCH cheaper method and your tomatoes will like it too!

Thanks, Snaz ... maybe in the future
I already have this bottle here to use up to Kill Some Algae

I had only bought it for a backup, but now I need to use it

[gregzz4]

Anyone want to stick their neck out there for me and tell me my math is correct ?????????

It's all good Snaz, tell him what we all need to know ...
Hijacking is OK when we need to learn

You gotta keep us in the loop Greg as to how that works. I'm upping my Mg dosing as well to see if I can get rid of this Dictyota algae in my tank. But with the BRS Mg they have a calculator right on their website to figure it all out. Hopefully we shall both prevail!
