Hi there, I'm fairly new to the hobby and currently have a 50l tropical setup. I'm on bore water and get water with a p.H 8.5-9.0 and a dKH of 8, I'm told Malawi and Tanganyika Africans will suit this water. So I looked into them and I quite like the fish and the tank environment (rocky), long story short I want to start a new tank. I'm a student so it will take some time to get everything I need to start the tank (over 4 months) and get everything running. My thinking is for now I will get the tank, then build a solid stand, then filters etc etc. Right, so my question is.... I know go as big as you can is the rule of thumb but does tank dimensions make a difference? For example, I am currently looking at two tanks Tank 1: 262 liters 1200 wide, 390 high, 560 deep Tank 2: 338 liters 1220 wide, 600 high, 460 deep So yes tank 2 has way more volume but tank 1 has a bigger foot print that can be used for more rocks and will allow for more caves. What would you guys recommend out of the two tanks? The other thing I have to keep in mind is that my house is on piles, the tank will sit partially above 2 piles in a corner against two exterior walls. The stand I want to build will be 1800x600 and will be real solid to spread the weight over the entire footprint. I'm thinking I might need to brace the floor some more, what experience do you guys have with this? The tank will sit perpendicular to the joists and the joists are 500mm on centers. If I went with the 338 liter I figure after I add the weight of the water, glass, substrate, rocks, lights ,filters etc. I am looking at 650 kg's. That weight makes me real nervous when I think about it. Well that was a mouthful. Any input is appreciated Thanks
