hi there, i am doing a guerilla grow in the aussie bush, water here is at a premium and hard to get in to site, i have a 1000 litre tank that had seasol fish fert added but wasn't used. a week later it smells like stagnant pond water, i assume it has gone anerobic i would say. my question is, can i still use this water or will it harm my soil/plants? i don't want to toss it away if i don't have to, thanks for any info,
