Many years ago in a previous life I owned a tropical fish shop, making my own tanks and stands. I never made a "proper" carpentry joint on any of them. If looks did not matter, pieces of rough swan timber overlapped and screwed got the job done. If looks were important, I used wood faced conti board over a soft wood timber frame.
The most important thing in any hobby is to enjoy what you do. If you try to get too complicated too soon the frustration of learning how work all the jigs and equipment properly will drive you away.
What are the dimensions of your tank? 30 litres is quite small (only 30 kgs weight) and sounds like a 2ft long,so not a major issue on building strength unless the overall shelf is 3 or 4 times that length.
If the tank is less than 3 ft long use a thin sheet of polystyrene under neath to stop any grit from scratching or breaking the glass.
When youve made your first item, and decide you want to make the next one better, THAT's when you start to buy the tools you think you will want.
It is a small cube of 30x30x35cm so just 1ft long so it seems it won't bit a problem at all and I am just overthinking this. The cabinet does need to be about 3ft in total but I want to divide in half so don't think it will a problem.
I understand what you say about equipment but to be honest I am the kind of person who loves to try new toys so I actually want to buy everything at the moment I am just trying to be reasonable and not spend a fortune on things I will probably never use again. And budget wise I can probably spend about £300 in tools for this so can definitely afford one saw the question is which type is the most useful. I am tempted by a sliding mitre as it would allow me to build the structure that I could then lay sheets on tops and sides which I could get pre-cut, but at the same type a circular saw allows me to cut both but it would be less precise I am guessing. Does £300 also need to include clamps which adds up quickly
