I'm just wondering if it's ok to use the above instead of mgs04? I've managed to find it cheaper than buying mgso4 and adding postage onto that too. If it is ok, would I have to use more or less of this stuff compared to what I'd normally use?
My tanks 120 gallon so I'd normally add 36 tsp of mgso4, but if I buy this stuff, I don't want to end up not using enough. I'm useless when it comes to this
According to to the last post in this thread viewtopic.php?f=11&t=16874 it states that mgso4.7h20 is 9.8% magnesium and on our sponsors sights their mgs04 is the same so I presume I'd use the same amount??
