I have been searching for some plant anchors online so I don't have to use fishing line etc to anchor them. Most places sell the lead plant anchors and I have been skeptical of putting lead in my tank as I have shrimp and don't want anything leeching into the water. I found some plastic ones on a website and I thought I would share.

They are a flexible plastic disc that you insert the plant stems into. Since they are flexible they won't pinch the stems too much. You can just pile some substrate or gravel around the disc to hide it or it may be useful for plants that can't be "planted" and need exposed roots. Real cheap too, $1.89 for a pack of 4. Also I called and placed my order over the phone as they website rounds your total up to $15 for small orders. Over the phone, they only charged me $2 for shipping since they are lightweight and small.

Some people like them. They never worked for me and I gave mine away.

They are buoyant and tend to float up regardless of how much fluorite I piled on top.

They are not small and if you need denser planting you have to stagger them on top of each other. That makes them float up even more.

They are light ivory color and I always saw an edge here and there.

I'm with OVT, I didn't like them either.
If you want to try them, you can make your own from the bottoms of small drinking water bottles. A judiciously placed rock can be a big help, until roots take hold. I went with EcoComplete substrate, and the plants stay anchored very well with it. :smile:

I use this all the time. Well worth the money. Just cut the middle as big as you need it to be. The plants will slowly push them off. Once this happens. You just wash them off and reuse them again. You will save money in the long run.

Ok, so I received the anchors in the mail today, and just got done using them to plant a few things. First off they are NOT buoyant as OVT stated. Alone they sink right to the bottom of my tanks. They are flexible and rubbery perhaps made from a silicone like material. I used them to plant 2 things, some anacharis and bacopa. The anacharis they pulled right to the bottom and didn't require any gravel to be placed on top of the disc. The bacopa must be more buoyant as it would float up a bit. I moved a small bit of gravel onto the disc and problem solved. They seem easy to use and so far I'm happy with them. You can easily cover the disc up so you don't see anything exposed. On the package it specifically says "non toxic" and "FDA food contact safe material". I used to run restaurants and this means the FDA has approved this stuff for any food use, i.e. you could make drinking cups or plates out of them if you wanted and would not leach any chemicals or bad stuff into food. That's good enough for me and IMO, much better than the lead weight strips sold commonly for plant anchors.

BigDog, How do your plants push them off? It seems like the roots would grow underneath and then the plant would be on the top side so seems like it wouldn't be able to free it self. Maybe I'm just confused. If they are reusable even better.
