That s right uneven pressure on the base of your tank.
Uneven aquarium carpet.
As a recommendation try growing this grass in a darker substrate like gravel or dark sand.
The real question is the floor under the carpet.
Under 30 gallons shouldn t be a problem for any floor that doesn t flex when you walk on it.
So i recommend having styrofoam under it to balance out the load.
The carpet pad over uneven subfloors will wear unevenly and quickly with the pressure from feet and furniture causing the carpet and the padding to wear out much quicker.
In short you simply plant this grass in its carpet form and watch it grow.
The carpet absorbs some of the uneven pressures.
Usually when you put an empty stand on a carpeted surface it will not move.
The only maintenance you ll ever need to carry out every now and then is giving it a little trim just to make sure it s not growing too long and overtaking your aquarium tank.
You need to fix the uneven floors by using a leveling agent or putting down a new subfloor before you install your flooring to ensure that your investment in flooring will keep its value.
So we just moved into our new house and while setting up my aquariums discovered the floors are uneven meaning uneven aquariums.
Carpet plants also offer an alternative to floating or vertically growing plants in their aquarium.
If it s an iron stand you can add plastic feet.
The carpet under it will be flattened to its maximum compression by the time you finish filling the tank.
If your aquarium stand has gaps then a foam mat is going to compress into those gaps.
If gaps are the reason your aquarium isn t level then a mat isn t going to help at all you need to find a way to flatten out the surface.
Additionally your aquarium lighting will affect every plant differently with some plants thriving in low light situations better than others.
And you know what that means.
If your floors are slightly uneven then pressure points will develop in the tank causing it to eventually crack.
When you get up to 90 130 or 150 gallons you should double check the floor support.
Picking out the right carpet plant for your aquarium is certainly tough especially when trying to select the right plants for beginners.
