I removed the front lower rail from the patio aquarium stand, so I could drop the sump right to the concrete. This removed 300 lbs from the stand, and dropping the pump sump 4” increased drainage. A lot!
There you can see the whole outdoor setup: the 55g Petco $1/gal special, the 30g rescue tank which is the pump sump, the Petco Brooklyn steel aquarium stand, the Brute insulated filtration sump, and the brown rain barrel from Home Depot.
I send all my drain water there, and wash filter socks there as well, in the 75g brown rain barrel. Then I pump the old water out onto my trees through this plastic irrigation tubing zip-tied to my fence.
I made two braces from 1x1x3/16” hot rolled steel (cut from a discarded bed frame) and bolted them to the stand with 1/4” bolts to reinforce it. I also made new styrofoam lids for the pump sump.
The Petco frame is not really designed for outdoor use it is getting rusty at all the joints. After I took this photograph I removed those braces to paint them, and I rubbed down the entire frame with a rust preventative oil.
I added a third sump pump to help feed the 55g, but I should just buy a stronger pump for it. Every available electric outlet is occupied now, by 4 pumps an air pump, and two heaters.
The air pump runs a stone in the brown barrel to prevent mosquitoes breeding there. It also contains some fat guppies who eat the mosquitoes, eggs and larvae.
Little Butterfish is over 6” now. He lives outdoors, but was born in this same 55 when it was on my hearth.
He is hybrid from a Red Zebra and an Electric Blue Johanni, and over 5 years old now.
