Flourite under gravel OK?

Matak · Mar 28, 2003

Hello to all you that are well rooted in this hobby!

I have a jet black gravel that I want to add to my tank, but I would like to add a layer of Flourite first so here is my plan: 1" of flourite on top of my existing substrate with 1" of the new black gravel over the Flourite.

Would the Flourite still be effective as a superior planting medium?

Sure... It will help! Lots of people go 100% with the Flourite and Onyx Sand. A mix is better than none at all.

But do be aware that layered substrates do not maintain their integrity in planted tanks. It does not take much moving and replanting for what was layered to become well-mixed.

to keep substrates in layers, you could use gravel guards. however, this would not fair well in a planted aquaria to my knowledge...

I tried this once - flourite on the bottom and sand on top. As RTR said, it ends up getting mixed together at some point....probably quicker than you'd expect.

I currently have a dual layer substrate (see specs below) that has been very stable. I propose to put a mix of fine and medium grade gravel which is #0 and #1 grade (1/8" and 1/4") on top of the previous substrate. I think (hope) it will remain stable.

Good luck to you Matak - that will be a new thing for planted tanks.

I have a dual layer as well , Latrite with sand over and gravel over that,. All in all I actually get very little mixing. At least it doesn't show!
