If this is a Q...bite me. Man cave.
Nice test. I BROKE THE CODE. I am old and asked the son how to post a pic off the phone. Won't go into it but, click, post to Gmail, send to persl email, click as attachment, post as attachment and SHAZAM.
Keep in mind there are 3 types of filtration: Chemical (Carbon), Biological (bacterial beds), and Physical (filters..fish poop)
See walls behind TV...future water ref. I like the stuffed fish motif. Dad and G-mom catches.
See below as to the "Verruckt". The small pink cichlid is about to go into it. At the top right corner, you can see the spout, the pvc at 45 degree angle.
Just shot this with the "moon" phase of the LED....cool. Could have had lightning going off as well, but they are sleeping.
The tank is ecletic. How can an Oscar be in a community tank you ask. Along with Jack Dempseys? Gouramis? Silver Dollars? small malawi cichlids/giant dimios (oscar food)? Answer is how they were raised. (I am an old person; Patience is the key. I have planned many tanks and this one for years, since I was 15, so what is 2 yrs to grow the perfect tank?) The Oscar was one of the last fish added to the tank. He grew up with his friends and has not been fed live food. Can he be a bully, yup. He faces off with the mated Demepsey pair...2 against one. He eats out of my hand. Supposably they play with ping pong balls. I am going to slowly go back to a malawi tank.
There is 250lbs of rocks/boulders for the fish to hide in. I have tried to stack them up, and they fall down. Thus used strong tupperware frames(with shale glued to the sides) and composite deck post siding squares (hard to see below Oscar on the left) cut to make hidy holes.
