I bought this tank on a popular "get rid of your unwanted junk" app. It is a pentagon 49 gal tank and stand. I should have steered clear but I like the end result I came up with. 3 months ago is when I acquired the tank. It was apparently leaking towards the top. I had no clue and the seller didn't share this info. I just thought they were lazy and weren't keeping it clean and filled properly. I had to completely remove all the old caulking. First tank I have ever re-sealed. By the way, there are no videos on how to do this with a pentagon tank. Probably because it is a freakin pain in the rear. So I took the time to do it properly from the many videos I watched on other regular tanks. It took about a week of off and on work to complete it. Afterwards it sat for 2 weeks with water in it to make sure I didn't have any leaks. Not a drop spilled. Super proud of myself btw. I took my time gathering supplies as I threw out all the crap equipment that came along with the setup. Fast forward 3 months. I got a wild hair today and decided today was the day. I have been soaking manzanita for at least a month and a half. It was time. I have been plotting my strategy in my mind since I got the tank. But today I was going to do it. So I started with seeing how I wanted everything set. Nope. That's not it. I like this better. I had decided on fluval shrimp friendly stratum and pea-pebble river rock. The rock would go in the middle where the cardboard is and the fluval on the outer parts. Placed some ugly rocks under the stratum so my nice rocks won't sink. Manzanita bases buried in the back corner. I started filling it up. Using a small plate sitting on the gravel and a bowl on top of that. Slowly at first. Water never got cloudy. YAY! So far the process has been, time consuming, but really smooth. It's been super fun. Please forgive the wires. I will definitely be getting those hidden. I've yet to find a backdrop that I like. (I left plenty of room to work between the wall and the tank) So here is what I ended up with. I'm very proud of my second tank and first all natural set up. Let me know what you think.
