As promised, details about my custom corner filters. You may have noticed them in my other tank pics but this is how they were made. I've cleaned them up so they're ready to go when the new stand arrives.
What you will need:
plastic bread boxes
plasti-dip (color of your choice)
Drill
PVC pipe cutter to 1 1/2 " - 2"
1 1/2" PVC Pipe
1 "T" Joint 1 1/2" PVC
Bio Media of your choice (I use Bio-Bale)
I ordered plastic breadboxes from Amazon. A center hole is drilled into the lid, 1 1/2". Smaller holes drilled around the perimeter of the lids, about 5/8" each. Drill holes at bottom of breadbox.
Paint with black plasti - dip. This stuff cures inert and is durable. I would have used the green but it was out of stock. Doesn't scratch or nick at all. Usually takes 48 hours depending on humidity and temp but I waited a week. Soaked for a day and was good to go. You can choose from many colors.
Cut PVC pipe 1/2- 3/4" longer than total height of lid and box. This makes a nice stable lip to sit the power heads in.
Attach PVC T-joint to base of pipe and place inside box. Fill in biomedia, push lid over center hole. Place powerhead basket in top and you're good to go. Easy peasy and extremely effective filtration. You can use this method for other large plastic food containers as well. They drill easy and are fish safe.
Take one of your powerheads to the store when buying pipe...that way you can test the width with your basket to insure a correct fit.
