Yeah, I think I’ll get all the supplies that I’ll need as best as I can and when I’m well and ready to actually setup I’ll make the decision if I want a different tank or not. And I was lookin at an Ehiem 2217 for a filter with some seachem matrix and seachem puragin for media
Probably not enough flow, 2 x 2217 would be better options.
I love Eheims... Marineland C series canisters are budget friendly good options, same as Sun-Sun.
Try and aim for ~10x tank volume rated filter output gallons per hour, this will leave you roughly 5-6x actual volume turnover.
So for a filter rated at 200 gallons per hour will only flow about 100 after head pressure and media.
I will strongly recommend an intake skimmer for the canister filter.
I will strongly recommend running at least half of the available media space with course sponges, where water enters the filter first.
Then run a small amount of Matrix in a media bag, then finish off the available space with fine filter floss.
Rinse the sponges out at least every other water change, rinse the media mag full of Matrix out at the same time (in old tank water) and replace the filter floss at the same time.
Cleaning filters every water change is best, but it's annoying. Filters trap decaying organic material, planted tanks have loads of it, so keeping the rotting mess of plant tissue out of the entire system is a massive step in algae control.
The reason why you don't need that much biomedia, is because the substrate will house the majority of it, and plants under high light / CO2 will uptake a lot of ammonia before it has a chance to convert into NO2 / NO3.
Plants prefer ammonia as a nitrogen source...
A little bit of biomedia acts as a buffer just in case, just keep it clean so it doesn't plug up, that's why I recommend placing it in a filter mesh bag, this makes it very easy to remove and rinse out in old tankwater.
