I am in the process of making the transition from years of freshwater aquirium keeping to reef ecosystems. I am looking to purchase a 135- 150 gal. tank and I am interested to know the general consensus of glass vs. acrilic tanks. Scratching, I get it, but intuitively it seems like the heat folded front edges of an acrilic would have fewer joints likely to leak. Any input appreciated - newcomer, Eldog. TX.
