Travis Posted May 7, 2022 Share Posted May 7, 2022 (edited) I am working on my first tub pond. I took inspiration from many different sources such as @Dean’s Fishroom @Cory Serpa Design etc. If you see something that you came up with and I haven't mentioned you please know that I am not claiming any of this as my own. I have mashed together ideas into a pond experiment that I'm hoping works well for my situation. I wanted to share progress and maybe get some feedback if anyone else has ideas or has tried any of this previously I live in Wisconsin so overnight lows aren't plant friendly until about mid May. I have the tub filled and cycling but I will have to add update photos once I can safely plant and add fish. I started with a 70 quart (17.5 gallons) Muck Tub from a local farm supply store. I drilled a hole for a low profile drain that I had. I added this to keep the water level several inches below the rim and if it rains heavily act as a over flow to maintain that depth. I wanted do a combination of emersed plant filtration and air driven undergravel filtration so I will be adding a plastic 12 inch pot to the center of the pond. Finding a pot that wasn't tapered so that the base was more stable was the most difficult part of this build. To get the pot sitting at the depth I wanted I had to add 2 patio paver bricks to the bottom of the tub. Using a hole saw I drilled holes around the pot. These allow water in for access to the plant roots and the undergravel filtration. I siliconed in strips of knitting mesh as a barrier to hold substrate in but maintain water exchange. Another paver was added to the inside of the pot to increase weight/stability as some of the plants im considering grow quite tall and on windy day could cause the pot to shift. I added a cheap adjustable uplift tube that I purchased online and filled in the space around it with small lava rock. Above this layer I added another piece of knitting mesh cut to fit as a barrier to keep substrate from filling in the bottom of the pot. I am using layers of extra substrate that I had on hand to fill the pot. I started with a base of Fluorite on top of the knitting mesh followed by a layer of Stratum. I only had enough spare stratum to make the 2nd layer a few inches deep so I capped the pot with more Fluorite. The goal here is that pot is driven by a small air pump that lifts water from the base of the flower pot and exits into the main pond. Water returns through the sides and surface of the pot and is filtered through the substrate and nutrients are taken out by the plants. I'm currently running a heater to keep overnight water temps up but once overnight lows increase I plan to remove the heater and only run the air pump until October. The tub is small enough that after draining down I should be able to move it indoors for the winter. If things work out I will add updates in the future. Let me know what you think Edited May 7, 2022 by Travis 7 Link to comment Share on other sites More sharing options...
