Ok, so I made it over to RMS to check out this special on the Seapora 135 gallon tank.
It is a standard tank with dimensions of 72Lx18Wx24H, no drilled holes, but has both bottom and top bracing. You can see in the picture there is also added bracing by use of glass along the middle brace and both ends. It comes with a standard looking stand, LED lights and glass top. I did not check the stand out much as I would not have used either. I just don’t trust these stands with this much water weight alone. All the corner and bottom seals holding the tank together looked good.
Now if you are looking for
just a tank only that is drilled, they also have a Seapora 135 gallon tank that is predrilled in the bottom corners and have corner overflows for basically the same cost of the previous tank ensemble mentioned.
Now my two cents for what it is worth.
The first tank mentioned would make a great fresh water display tank. Slap on a HOB filtration unit, a couple internal low volume pumps and you are pretty much all done. To use this for Saltwater, I don’t know. Taking a chance with drilling a couple holes in the glass on the back panel after spending this much money, would give more than just the heeby geebys. Now if you were to use a HOB overflow I could then see a lot of possibilities start to arise. I mention HOB overflow because this is what I successfully used for the first 25 years of the 35 years I have been keeping saltwater tanks, all until the craze of drilling holes in glass came around a few years ago.
Hopefully this gives you something to compare to, with the tank sale going on at Bluefish.
