Last weekend my friend David and I spent a great deal of time researching the best way to modify this 4-foot long tank for future marine use and accessability. It seemed the only way to move forward would be to drill holes for 2 bulkheads near the top and plumb in a wet dry filter that can later be converted to a refugium sump, if need be. So, the drilling began. Two drill bits and several hours later, the holes were completed and the tank was plumbed. In order to make up for head loss on the pump, we decided to power the return with a Mag 12. I also left a “t” in the line to accomodate a skimmer sometime in the near future. To top off the job, I painted the back of the tank using a black, water-based latex paint. Looks great! For now, the Koi are enjoying the revised home. However, I am a bit anxious to convert this to a saltwater unit sometime in the near future.
