so be being financially reckless, I impulse bought a new 125g tank and wanted to keep cichlids in it as I deemed my 55g too small for the cichlids to be comfortable. I am also a poor uni student so I will NOT be buying some Fluval canister filter that costs so much I won't be eating lunch for the next 9 months because I like food and not starving like most people I'm sure. so I have decided to actually use my engineering degree for a real life application and build a filter myself. don't worry about build difficulty, i'm stubborn and meticulous to detail so it can be as complicated as you'd like but when I can't source vital parts that's when i get shitty. so if you're going to suggest a filter made with weird parts, please provide a link/source them so I don't spend half my life looking for some weird component that only exists in Bangladesh or something. at the moment im leaning towards a high flow rate trickle tower made with those plastic drawers you had as a child that you'd keep your lego in (im sure you know what im talking about hahaha). but if anyone else has a better idea then please share. also it cant be super difficult to clean because without exception, I will get water absolutely everywhere and i'm renting so id rather not be responsible for floor replacement. its also in my living area so it can't be super loud. also, can someone source some bulk buy scrubbies for bio media? i live in New Zealand which means we don't have Walmart or apparently scrubbies (and i went to 300000 2 dollar shops with no luck) so if someone could drop a link then ill buy you a box of steinies or something xx also also, if anyone wants to suggest stocking then feel free but only if you feel frisky.
