Tratanu Posted August 8, 2021 Share Posted August 8, 2021 Hello, I built my own stand and I have leveling problem. 2 of the 4 corners on my rimmed 75 are not flat. It is not a large gap, but I am still concerned with it breaking a seal. Am I able to use something like hardie board (cement board) and shims under the tank to level or does it need to be plywood? I just have leftover board to use but I am unable to get ply wood right now. Link to comment Share on other sites More sharing options...
Daniel Posted August 8, 2021 Share Posted August 8, 2021 How large a gap? Small gaps don't bother me. Link to comment Share on other sites More sharing options...
lefty o Posted August 8, 2021 Share Posted August 8, 2021 main thing is that the 2 ends are flat, and level with each other. Link to comment Share on other sites More sharing options...

Odd Duck Posted August 8, 2021 Share Posted August 8, 2021 I’ve heard of people using (but not tried myself) thin yoga mats under tanks to help fill in small gaps like that. 1 Link to comment Share on other sites More sharing options...
Ryan F Posted August 9, 2021 Share Posted August 9, 2021 I had a problem leveling a 10g tank on a cheapo petco stand. I used some neoprene tape to fill in the gaps and make sure spread out the load. Link to comment Share on other sites More sharing options...
jeNks Posted August 9, 2021 Share Posted August 9, 2021 (edited) Why not sand the perimeter of the flat? At most that looks like a 1/16th. Level is not "true".. leveling can be a dead centered bubble but can easily be off an 1/8th over 4+ ft. That's why I love dead on measurements.

Daniel Posted August 9, 2021 Share Posted August 9, 2021 @Tratanu From your photos that looks like a very small gap, not the sort of gap that would be a cause for concern. Link to comment Share on other sites More sharing options...

As I under stand it. Just the corners supports the pressure. SO if there is a gap in the center of the stand would that cause any issues? Sorry to ask so many questions on this I just want to make sure everything is right, before adding anything. Link to comment Share on other sites More sharing options...

There was no substrate or anything in there. I just put the tank on to do a leak test. But then I saw the gaps and was concerned. Link to comment Share on other sites More sharing options...
BF McUmber Posted August 9, 2021 Share Posted August 9, 2021 I can't tell from the pictures if the black stand is metal or wood? I'm going to assume that's a screw hole I seeon the first picture. I had the same issue with the wooden stand I built. The corners were not touching till like 3 inches from the corner. (My gap was only the size of a piece of paper or two). Blindly remembering Cory saying that the tanks are designed to touch at the corners, I sanded the middle of my boards down so that the corners of the tank were physically touching. I shined a light on the opposite side of the tank and sanded until I could not see light at the corners but then could consistently see light in the middle. For further confirmation, I also tried to slide a piece of paper in under the tank. I wanted the paper to stop within a half inch of the edge of the tank. Also, when filling the tank, some areas in the middle that had gaps start to tighten up. 2 Link to comment Share on other sites More sharing options...

I think I will sand down the top until the to ends touch better, 1 Link to comment Share on other sites More sharing options...
