About time! LolLol, I'm finally getting black moors and I'm having to keep them in another room because the other tanks have raised the temp too much for them in my room. The funny part is that It's gonna be a double 55 with black moors on the bottom and discus on the top. Also look out for my goldfish thread, I'm about to post an update in a minute.
a plywood aquarium is one thing, I would probably do that, but a concrete tank is more like a pond, if you're looking for a pond then that would be fine, but an actual aquarium would require a glass panel
if you think a concrete tank is like a pond then you've obviously never seen one or you're thinking of something else. I'll pull up a pic of one.
Oh, yeah I was thinking of a type of pond, I just googled a concrete fish tank and saw a pond, so basically it's steel rods in the ground with cinder blocks around it to make up the frame and then you fill it with concrete and then add in acrylic/glass panels where you wish too, but that sounds awfully hard. You need to first get the base right, with the steel supported and all, then you have to get the frame and all right, then find some way to get the entire sheet of acrylic/glass to be in the tank firmly. I don't know about you but that sounds hard to do, installing the viewing panel and support the tank and making sure it's waterproof and all just doesn't sound easy
