I just purchased a 90 gallon drilled aquarium that is 48 x 18 x 25. The stand I purchased is only 24" high. I am planning on using a 30 long as my sump and putting baffles in it. The sump measures 36 x 12 x 17 which leaves me with limited space to get a skimmer out. Which skimmer would you recommend I purchase that I will be able to get in and out of the sump and stand to clean.
