We are planning on making another big tank. The disadvantage with DIY aquarium is deciding on the best dimensions! The one we already made measures 160 x 60 x 60cm ( 63 x 23.6 x 23.6”) with a stand 84cm (33”) tall, I like it and and originally I was thinking of another the same size. But my husband suggested making the new one 2m long (78.7”), and that sounds good to me! I am particularly unsure about the height though, both of the tank and the stand. I think 60cm is good for the depth (front to back) but I can’t decide whether to make the tank 60 cm or 65 cm tall. 65 (25.6”) would add more volume and my husband thinks it might look more proportioned, but I am not sure, maintenance might be more difficult, and using 12mm glass 60cm would have a higher safety factor. We will make a decision soon, but just wondering if anyone with experience of larger tanks has any thoughts on the ideal dimensions.
