or hood be replaced? Ok after much debate and research I decided I am going to purchase a SeaClear aquarium. I was hesitant to go with acrylic because I heard people mention it scratches, but everyone in the house feels the extra strength of the acrylic is worth it. Plus I plan on being gentle with the tank. Anyway...People generally give these tanks good reviews however, almost everyone complains that the light fixture that comes with them are bad. Can you replace the light fixture with a better one? Also another complaint by reviewers is that the top doesn't come off and that there is no hole to feed or do maintenance. Can someone elaborate for me. Thank you.
