Reef Tank Heaters

Suggestions for a 5g mini bow reef?
I’m going to set up a 5gal mini bow as a Reef Tank. I’m thinking of using a glass 5gal under it as a sump with a refugium, skimmer and heater. I don’t know how easy it will be to drill a 5gal mini bow as they are acrylic? I will use two 20w compact florescent 50/50s for lights. Any suggestions are welcome.
Hey i think what is best
for u is a tank not a bowl
cuz fish can just live in
a small tiny space
it is like living in a bathtub in ur entire life
with ur feces etc….
cant u show mercy to ur fish?
well it is ur choice Good Luck!!!!
