My 55 gallon only has perimeter and hasn't failed me yet (knock on wood) its been going for 7 years. Should I except something?
Yep,I have a similar stand for a twenty high and the floor of the cabinet inside has sunk in a few inches from water.12 Volt Man;2971669; said:I think the stand needs to be replaced. particle board stands are strong when dry, but when they get wet, the particle board swells and weakens.
your fine for a while, but eventually you will need a new stand.
