The reason i want trace elements without Iron in them is because i have 100%
flourite gravel. So i dont need to add as much iron if any, but cutting down
on iron would also mean limiting trace elements unless i can get trace
element without iron.
I have found out that www.animal-house.co.uk/ has started selling Kent
marines aquabotanic range of pmdd www.kentmarine.com/html/botanica.html
which has trace element-iron mixture.
