I'm hoping to run low tech, and EI sounds like something I don't really want to get involved in. Ideally I'd like to be able to get away with dsoing ferts no more than once a week, so is there something other than root tabs that might be appropriate?
I've also been reading up on TPA and it says it contains copper.
AFAIK you should aim for zero copper for shrimps so I'm wondering whether the concentration in TPA is likely to be a problem? (I've done a fair bit of searching on this but haven't found a definitive answer.)
