Corbidorbidoodle Posted April 23, 2022 Share Posted April 23, 2022 So, this is just sort of a PSA/learn from my mistake. I set up a couple of new tanks just for experimenting. Various scaping and whatever. One I bought plants for and the others just plant trimmings. Since I've seen people make DIY root tabs using Osmocote, I thought I could just sprinkle some on the bottom of the tank before I put in the substrate. I'd say I put in about 10 tabs worth. Now, after a few weeks, the moment I dip a test strip, the Nitrite and Nitrate pads go instantly bright fuchsia! There's so much nitrite! Weirdly, there's no Ammonia. Also, the lower tank has a bunch of guppy mutts and low grade cherry shrimp. They're both doing great. Guppy babies and everything. I'm gonna scrap both tanks this weekend and start over. Is it possible to use Osmocote this way? Did I use too much? Not enough substrate? I'm wondering if, for this to be effective, maybe I'd need regular sand rather than pool filter sand to cap it properly. I'll probably just go regular substrate when I set them up this time. No need for me to get fancy. 1 Link to comment Share on other sites More sharing options...
