Hey all. Here I have a mini guide about my DIY tank stands and racks. I also have some questions at the end I would like you to answer, I need some help. Ok, so I found this tutorial by a person on youtube named Aquarium Co op and these are by far the easiest tank stands to set up and build. It cost me about $15 total. I bought six cinderblocks, and 3 long planks of wood. That's it. Put them on top of eachother and they hold tanks!! I will post pictures obviously. If you want a nicer one, you can do what I did twice and double it, put a curtain or something around the sides and top and it will make a really nice tank display stand. Here are my pictures: http://imgur.com/a/5X4sr Also, for my question. On the right side I have a empty space. I set this up because I want to breed some rainbowfish, guppies, swordtails, mollies, endlers, etc. Most livebeareres with some small exceptions like the rainbowfish, maybe GBR's, and for sure shrimp. My dilema is that I don't have space for a bunch of 10 gallons. Now obviously I could make more or make another level but I don't want to. I can fit a whole lot of 10 gallon tanks underneath the stand but I don't really think that gives me enough room. I've uploaded pictures; after seeing them, would you agree? I can reach my net in to net out fish but there isn't much visiability. I'll wait a day and maybe it will change as the water was stirred up. As for the spot on the right: It's 22 inches long, and 16 inches deep (front to back). What combination of tank(s) could I put there to max out the space? I really want like a 10 gallon for each species/strain. I could just put my guppies all into a giant tub or tank I have but I want to work on strains individually, so I would like a 10 gallon for each strain AND species. Bottom line: Would you think it's ok to have lots of the 10 gallons lined up lengthwise? What tank(s) combinations would you recommend for the space on the right?? Thanks. http://imgur.com/a/5X4sr Actually I might want to make a sump as I have no other power slots left and I can only imagine how much power I am using up for heating and using bubble filters on 10+ tanks.
