remove metal hose clamps, will rust and contaminate water. Ocean Aquatics has plastic clamps

Use electrical tape or black paint to cover up the clear hose. it WILL get algae covered inside and restrict flow, requiring frequent cleaning. Just dont use tape below warerline
You might want to put a union on the return pump as well? Not sure how tough those hoses are to remove from the barbs. Mine are really tough. the pump will need to come out for cleaning
Other than that, looks great
