whats the best way to change the water, sorry for all the question, researching as much as possible before i do anything, also how much do i need to change?

What about protein skimmers?

is it possible to use a jebo R338 (35 litre) to use as a nano tank, What equipment do i need do i need a sump or is the internal filter fine?

Hi, kinda new to fish as there is always lots to learn, so far i have 3 tanks set up Tank 1 A jebo R338 with a black moor and a fantail, and pretty pink stones Tank 2 A Aqua one 620 with a kuhli loach and a rainbow shark, 2 apple snails and lots of baby one( i really dont like them) Tank 3 A 200L with 4 angels and a brittlenose pelco

Very new to this, why are u adding salt, i only thought u did that for marine tanks?
