is bad for a planted tank. do i just take those out and let the

Yep - let the filter run at the very least for good biological filtration
(i.e. the wheels). You might want to use a layer of mechanical filtration
media too though (i.e. filter wadding the water would have to go through so
solids are trapped in the filter and you can remove it periodically). Good
luck and later!
