Do any of you use plant fertilizers in your shrimp tanks? Any detrimental effects to the shrimp? Which brands do you use? Thanks for any experiences you care to share....
In the past, I have used most of SeaChem's and Kent's lines as well as my own mix. All I use now is fishfood.
If you have growing, healthy plants and you follow the manufacturer's instructions, there should be no trouble. Any potentially dangerous heavy metals will be taken up by plants or bound by the substrate (assuming you have a decent substrate).
