i would like to get my mg. up to 1350

since i live in MX. there are no lfs. in my area but there are lots of chemical companies what would be the best product to use to raise my mg. mg.sulphate mg.chloride added to my reef at no more than 100 ppm a day .

This article discusses DIY solutions:


ESV, Warner, Kent Tech-M, and Salifert are all good magnesium supplements.

so am i better off as far as polluting the tank goes with ,(sulfate,chiloride), buying a brand name mg. suppliement?

from what i read on the link you provided if i go the ,epson salt,mg chloride.i will still be in danger of messing up my tank ,

i finally seem to be getting a handle on things and dont want to mess anything up

if i order one of the brand name mg. suppliements do i stiil have to worry about ,sulfate,chloride,ammonia being elevated in my tank, thanks for your time

The brand name supplements I gave should be safe. I've been using Mag Flake, which, if available, will save some money.

You can use Epsom Salts alone disolved in pure water. Just keep a good schedule of water changes of 10% per week and you will be OK.
