What are these yellow round balls in the substrate?
Looks like you have critters in the tank that love to move substrate around. Both fish and Malaysian Trumpet Snails. So that would explain their movement from the other side of the tank.very good point! I never thought about it. I do fertilize with osmocote capsules. But the balls are much smaller when I put the capsules in. And the balls that I see now are much bigger and if I break them they some sort of liquid inside. Also they must be traveling within the substrate because I only put them in other side of the tank. Mystery ....
If you get yourself some good red clay (the natural stuff) and mix in your own dry fertilizers, you can easily make your own root tabs. Just mix/knead it up well and then make little pea-sized balls. Dry it out and they'll keep for ages. Probably costs about the same as a container of Osmocote and lasts a lot longer.But osmocote capsules are so cheap
where do you get good red clay? I live in Hawaii. We do have red dirt but I am not sure it is the same.good red clay (the natural stuff)
If you have Michael's or a similar-type craft/art/ceramics store (maybe Ben Franklin?), you may be able to get your hands on Mexican red pottery clay. As long as it's all-natural and doesn't have additives, it should work well.where do you get good red clay?
Make it dirted, I struggled for so long growing anything in sand and rocks until I put 2inches of pot mix under it. Who would have thought that plants love soil???For the fish, I have tetras, culi loach, coreys and big yoyo loach.
I guess snails and fish would explain the movement of the balls.
they look so annoying maybe I should change the root fertilization tabs. But osmocote capsules are so cheap
