Hello! I am setting up a container pond for my mother for the summer. I have experience with planted aquariums, but have never attempted something like this before. There is some disparate info online so I was hoping I could get some answers from you all here
I am thinking about a 110 gallon Rubbermaid stock tank. Is something like this deep enough to help keep the temperature relatively stable? https://www.tractorsupply.com/tsc/pr...k-tank-110-gal
We'd like a few small fish for interest and to eat unwanted critters. I'm aiming to keep the livestock load low so I can avoid using a filter if necessary. Is going without a filter doable? If needed, it's not an issue -- just wondering.
I have been contemplating maybe 3 (max) feeder goldfish, and perhaps some snails. Are goldfish a good idea without a filter in a setup like this, or is there another species that might fare better? Barbs? White clouds? Betta sorority? Mollies or guppies? How many would you suggest for a good balance, considering this will be well-planted and frequently water changed?
The container pond will be on a back deck and mostly in shade but with enough sun to keep the plants happy. We live in northern Nevada, so it gets a bit warm during the summer (upper 80’s mid 90’s), and around 60's during the night, which is why I wanted to be sure the water is deep enough so the possible fish and plants don’t overheat. In the winter it will likely be moved into the garage and/or heated.
I am also looking for something to add water movement for circulation, maybe a small fountain? Air stone? What would you suggest that works best with this kind of stock tank?
Would a CO2 infuser be necessary or a good idea for a container pond this size?
Thanks in advance!!
