I used to maintain a 180 gallon Ocean View that was a dedicated reef tank. I have been maintaining tanks for a long time and am quite proud in the care I take to do the job correctly. After taking care of this tank, I would never personally use OceanView for a reef or marine tank due to what I consider to be questionable sealing practices. The silicone is often times thin and or inconsistent and in this case simply started to come apart and peel away from the joined corners slowly at a time. I observed many more than just this sample that were just as bad if not worse in the sealing department.
That said, they are affordable :wink:
PS- The OceanAtlantis tanks are in my opinion a much better tank due to the very hefty glass (suckers are heavy), consistent sealing practices, and lets not forget the metal center bracing.
