DannyC Posted January 6, 2022 Share Posted January 6, 2022 (edited) Okay, so I am working on this tank and am about to add fluval stratum to it on the right side which is where I will be planting. Currently you are seeing lava rock in that area and my question is this. Can I put the fluval stratum on top of this or should I remove the lava rock and put the stratum on the bottom and then cap it with the lava rock? I know that if I put the stratum on top of it it will make its way down in between the lava rock, but I'm not totally sure that's a bad thing. Wouldn't that just promote better water flow though out the substrate and prevent any anaerobic areas? The only thing I can really think of that may be an issue would be something root related like roots growing down past the stratum into the lava rock and not getting the same nutrient quantity as it would if it were on the bottom. Thanks for any insight! Edited January 6, 2022 by DannyC Link to comment Share on other sites More sharing options...
