Container filters or hang‑on‑back (HOB) units ranked for 200-- 400 gph are common.55‑gallon and larger: Larger volumes minimize the frequency of water changes, however they require more effective filtration, heating system wattage (frequently 200 W+), and constant lighting to support plant development.
