It comes into our attention that the bonus mounting legs might not fit some of the tank's wider plastic trim. Some of the marineland tank has much wider trim + lips for the glass top resulting of the bonus mounting legs won't go over.

There is really not much we can do as we cannot order the bonus mounting legs in different width to fit every tank's non-standard side width plastic trim.

There is some solution to it:
1) not use the bonus mounting leg. The fixture can sit on top of the tank.
2) the coralife legs will fit our fixture.
3) if you are handy, remove the part of lips that holds up the glass top (only the area to fit the bonus mounting legs).
4) we can also order you a hanging kit.

This does not affect our 36" model. So far, we have no problem of not being able to fit for any 36" model.
