Acrylic is several times stronger than glass.
It will not shatter, crack, or leak like glass can.
Acrylic is clearer than glass. Glass has slight green tint.
Colors and shapes look sharper and brighter in acrylic aquariums. Acrylic also allows
better penetration of your system lighting, which is especially important for reef systems.
Acrylic insulates better than glass.
Acrylic controls water temperature fluctuations, one of the primary reasons for fish
stress, disease, and death. Glass conducts heat and cold causing more fluctuations.
Acrylic seams are stronger than glass.
Acrylic seams are molecular bonds and actually stronger than the acrylic itself. Silicone
seams used on glass aquariums can dry out and weaken over time.
Acrylic seams are visually superior to glass.
Acrylic seams are polished and nearly invisible. Silicone seams
are clearly visible and have been known to discolor when exposed to certain fish
medications.
Acrylic is easily refinished.
If glass scratches it can not be repaired. Acrylic can be repaired with a variety of scratch
removal kits. Even internal scratches can be repaired without removing the fish or water.
got it from aquadirect, my question is I know acrylic is thicker than glass but other besides that how can you tell them apart?
