Its cool that you love the hobby enough to have multiple tanks. I probably wouldn't have too hard of a time convincing for an upgrade for my tank other than as of right now "why?" might be the biggest dilemma.. People don't just see that a larger tank means more fun

. Ideally if this all goes well and I can get a tank running and that looks better than a pile of rocks.. It could possibly get an upgrade.
I was really amazed to see that a stand isn't really that difficult to make.. I watched this video . I just am really confused on what dimensions I would use cause my tank is a weird shape.. but thats about it. I think the sump plumbing might even be more difficult than this build, but it sure would be nice to have a lot of room underneath. I never really realized that hardware stores literally have everything to diy at home.. The video quoted the cost of a stand built, from screws, 2x4's and some plywood was like $30.. and like you said, it was built really fast. I guess I was overthinking about how difficult it would be.
I barely have anything in my tank, other than rocks so I don't even see how it would be too difficult to really move my tank if I decided to move my tank do all this. I have a 30 gallon and 20 gallon rubbermaid bucket and a handful of 5 gallons if need be. I guess I just don't like disrupting my tank because it literally takes a visible toll on my blenny lol and I feel bad for him. Not sure if I ever included a picture of my tank, but here it is. I wanna break some of those rocks down, or just add new dry rock to build my aquascape out. Do you have any advice on building a sump itself? Where can I get some pre cut baffles? I am thinking about doing something similar to the picture I posted before, but unsure how that layout really is and was more interested in the piping itself.
