If I was you I would stick with the big names in aquarium filtration like Fluval, Eheim and interpet.
I have been using a fluval 404 in my tank for 2 yesrs now and I have never had problems and they don’t block
Like cheaper makes. At the end of the day you are mixing electricity with water so buy the best and never buy
Second hand aquarium electrical products as you don’t know what the previous owner did with them.
2 x powerful filters
2 x powerful heaters
1 x powerfull air pump for air stones etch ( for bubbles )
1 x powerhead for water surface flow (creates oxygen for you fish) flow just above the water surface
Rock work
And your fish.
