The old style carpentry method would be to use diagonal bracing on the bottom and back. How ever thay would have to be cut in on the bottom, meaning a notch as thick and as wide as your board would have to be cut and the brace placed inside of the notch and secured. The brace would run from one front corner to the opposite back corner of the bottom perimiter. It would be easier to just apply a layer of plywood to the outside of the bottom of the stand. That would only increase the height of the stand by the thickness of the plywood used and would not decrease the tank stands inner dimensions. For the back, a cut in brace would have to run top to bottom from one side to the other. Simply using a six inch or so wide piece on each side from the outter corner to the first stud would work nearly as well as long as it was well fastened. Such as a nail or screw every two inchs or less. Not having something to prevent diagonal racking or swaying in the stand you used as a pattern can be considered a design flaw. Design flaws are sadly common and often do not become seen by many until there is catastrophic failure. Like bridges falling down for no apparent reason and many bridges falling down during California earth quakes. Nature has a way of testing human made apparatuses and structures. Lack of diagonal bracing is easily remedied though. Just some plywood has kept houses from folding and twisting since the 1950's when plywood became a common building material. Bridges still use diagonal bracing. Those braces are used for the vaery same reason. A box to keep from folding flat needs diagonal bracing.
:bounce:Most pond pumps have steel parts in abundance in contact with the water being pumped. Impellers, seal springs, bearings and shafts. The Sequence Reef Flo Dart and Snapper pumps are about as cheap as you can go and still be safe with the parts involved and the electrical consumption is low. The cheapest source I have found is http://www.glass-holes.com their prices include free shipping and they run $10 to $20 cheaper than any where else I have seen. :D
:frustrat: And that is supposed to prove what? :shock:
Lots of iron I expect? Any increases in algae to go with the iron your putting in your tank? Pond pumps are not made for salt water, they rust, and all the oxidized metals go into your reef tank! Sequence makes pond pumps, but they modify them for reef use (they are their Reef Flo pumps), they do not expect people to use their standard pond pumps for a reef tank. I assume you have not modified your Lowe's pond pump.
