Koi Holding Tanks for Sale

Finding some sturdy koi holding tanks for sale on the market can be a chore. There are plenty of reasons to get this specific chore done though. These tanks have many purposes.

Koi holding tanks can serve as your quarantine tanks. A quarantine tank is where you put your fish if it comes down with a contagious disease like fin rot or dropsy. You can put them in the tank if they have parasites such as ich.

The reason for choosing this type of tank is because koi are large as adults and can’t fit your normal everyday fish tank. You need something large and sturdy to hold up to the koi carp you own.

Koi fry or fish that are only around six inches can be treated in your regular tank from Petco. If this is your situation, then ignore this post. You can get away with holding young koi in about anything.

      That review was blistering. I would be so mad if that happened to me too.  You could actually feel the emotion coming off of that page. Companies that make crap, forgive my crassness, will get it to all come back on them. 

      That’s why I include Amazon reviews in my posts often. I tell people when I think one product is better over another. I give suggestions to steer them toward things that work and away from a disastrous product. 

      I’m glad you look closer to see if somethings quality or crap. Thanks for reading
