L.W. Wetarm Posted December 17, 2020 Share Posted December 17, 2020 The new 29 is going to have some very heavy rocks going in. Is it a good idea to install one of those white plastic grids to the bottom to help spread the weight and cushion the bottom glass? Link to comment Share on other sites More sharing options...
gardenman Posted December 17, 2020 Share Posted December 17, 2020 I don't see where it would hurt anything to do that as long as the grid didn't dig into the silicone sealant along the tank edges. It could possibly create more anaerobic zones in the gravel as it would limit water transfer through the gravel, but that might not be a huge issue. If you're worried about the weight of the rock, I'd say go for it and see what happens. Link to comment Share on other sites More sharing options...
Administrators Cory Posted December 17, 2020 Administrators Share Posted December 17, 2020 It’s unlikely you need to spread the weight. However it could help if a big enough rock was to fall on a small point. I myself haven’t found a need to do this in my hobby. Link to comment Share on other sites More sharing options...
Fish Folk Posted December 17, 2020 Share Posted December 17, 2020 We've done this for a few tanks. As gardenman says, be sure to trim the light diffuser paneling a bit smaller than the exact footprint of the tank bottom so that it doesn't dig into the silicone. I will say though . . . if you're going to have African mbuna cichlids in there . . . they'll probably dig down and expose the light diffuser paneling. If you look in the attached photo, zoom in under the large piece of Texas holey rock (ca. 80-100 lbs), you'll see that they've dug down to expose it. 1 Link to comment Share on other sites More sharing options...
Brandy Posted December 17, 2020 Share Posted December 17, 2020 @Fish Folk That is a beautiful tank for a completely non-planted tank...I love the greenery at the top. 1 Link to comment Share on other sites More sharing options...

Thanks! We just cut to size and fold large pieces of filter sponge in half around pothos roots, jam it into the open tops of two aqueon 75 hob, and then . . . . fuggedaboudit . . . 😂 Link to comment Share on other sites More sharing options...

No, this tank will be a plants and small fish tank. I do know about diggers though. My Tanganyikan Brichardi (species only) have dug under every rock. I planned for that and put flat rocks under the hardscape and they dug under those. I’ve learned that Val will survive with roots totally exposed. 1 Link to comment Share on other sites More sharing options...
