I have started my shark tank/pond it will be 450 gallons and will be 40 square feet (8ft X 5ft). I will be using liner for cost and skill reasons iv used it before so iv gotin pretty good with it. it will be stocked with white spotted bamboos and banded bamboos. The design is pretty simple and sturdy probobly more sturdy then it needs to be but when it comes to water in the house and your sharks health more is always better. I just started tuesday and the latest pics are from today. I hope to have this tank ready for the summer so i cant start buying stock. i arriganly planned to post this when i was done but i just couldnt wait to share. I hope you enjoy and eny ideas/concerns are welcome has im only 19 and have been in the hobby sense i was 9 salt for for the last 3 so when it comes down to it im a newbee (done lots of reading thoe lol). i will post pics has soon has i figure it out. they will be up later today.
