Hey guys I have a question about how long chelated iron plant supplement iron good for. I just got back into keeping fish after taking a break for 5 years, just going through all my old supplies in the basement and found a bottle of iron that was opened but almost full still. Can I use it again or should I toss it?

Yes iron does change, I would definitely toss it....

Root tabs are much better, liquid ferts feed the algae.
I only use Osmcote root tabs, they are pretty cheap on EBay....

Ok, was just checking before tossing a full bottle.
