With my last 210 tank project which included my first DIY overflow and sump, it occurred to me how easily an overflow could occur from from either the sump tank or aquarium. While the overflow siphon can be stopped by a siphon brake hose during a power outage, there is nothing to stop the pump from overflowing the aquarium or for whatever reason the aquarium overflows with all the sump tank water, until now.
My new 160 tank stand will now incorporate a 4 inch perimeter water tight containment to catch tank overflow water and directed to two 1/2" containment drains back into the sump.
Below 3 permanent sides of the stand border trim containment are made water tight with silicone, the fourth side which is held by screws will be installed once the tank is in place.
Below, 1/2 inch holes are drilled above where the sump tank will sit for drains to be installed. Holes are lined with silicone sealant for protection.
Below are the 1/2" garden piping secured by silicone sealant. Note the 4th side of the boarder containment missing to allow tank install but will be sealed watertight once the tank is in place.
Below 4th side of boarder containment installed with 8 screws and silicone sealant water proofing. Not the drains inside the containment and behind the tank are ready to receive tank over-spill and direct it around the containment to the rear drains.
Below the final picture shows drains from under the stand leading inside the sump tank back to the pump. There are many variations that could be used such as a dry tank beneath the stand with a moisture alarm or marine bilge pump that would carry water back to tank controlling either an overflow or leaking/cracked tank preventing a flood and property damage.
