Costs, Gear, and Time: Planning for Hang On Back vs Canister Filters
Choosing the right filtration system is a crucial step in any aquascaping journey. Whether you’re setting up a lush planted tank or a biotope aquarium, the choice between hang on back (HOB) and canister filters can have a big impact on your costs, daily maintenance, and aquascaping success. In this guide, we’ll break down the costs, necessary gear, and time commitments for each option, helping you plan the perfect filtration for your aquascape.
Understanding Your Filtration Options: HOB vs. Canister Filters
Before diving into the details, let’s clarify what aquarium filtration offers for aquascapers and why HOB and canister filters are the most popular choices:
- Hang On Back (HOB) Filters: Compact filters that hang on the rim of your tank. They’re easy to install and maintain, making them ideal for beginners and smaller tanks.
- Canister Filters: External units placed beneath or beside the tank, offering customizable media trays and powerful filtration for larger tanks or advanced setups.
Cost Comparison: Upfront & Ongoing Expenses
Upfront Costs
| Filter Type | Entry-Level Price ($) | Mid-Range Price ($) | High-End Price ($) |
|---|---|---|---|
| HOB | 20 – 40 | 50 – 100 | 100+ |
| Canister | 60 – 100 | 120 – 200 | 200+ |
Note: Prices vary based on capacity, features, and brand. Always choose a filter rated for your aquarium size and livestock.
Ongoing Costs
- HOB Filters: Require regular replacement cartridges (every 2–4 weeks, $3–$10 each). Long-term, these costs add up but are manageable for smaller aquascapes.
- Canister Filters: Replacement media (sponges, ceramics, etc.) usually last several months. While initial refills are more expensive, they last longer, and some media are reusable after rinsing.
Essential Gear You’ll Need
Aside from the filter unit, here’s what you’ll typically need for each option:
HOB Filters
- Replacement filter cartridges or media packs
- Pre-filter sponge (optional for shrimp/fry safety)
- Aquarium lid or cover (to prevent evaporation/splashes)
Canister Filters
- Flexible tubing (usually included, but check length for your setup)
- Intake/Outflow pipes (glass, plastic, or stainless steel for aquascaping aesthetics)
- Media baskets (included, but customization increases efficiency)
- Quick-release valves for easier maintenance (recommended)
- Surface skimmer attachment (optional, for crystal-clear water in planted aquariums)

Time Investment: Setup and Maintenance
Setup Time
- HOB Filters: 10–20 minutes. Simply hang on, fill with water, and plug in.
- Canister Filters: 45–90 minutes. Involves assembling media, routing hoses, and priming.
Ongoing Maintenance
- HOB Filters: Quick and easy—swap out filter cartridges (5–10 minutes, biweekly). Scrub impeller and housing as needed.
- Canister Filters: More intensive—open unit, rinse media, clean hoses (30–60 minutes, monthly or bi-monthly). Less frequent, but more laborious.
Optimizing Your Filtration Choice for Aquascaping
Consider the key factors when choosing between HOB and canister filters for your aquascaped tank:
- Tank Size: HOB filters are best for nano and mid-sized tanks (5–40 gallons). Canister filters excel in tanks 20 gallons and larger, or heavily planted aquariums.
- Aesthetics: Canister filters can be paired with glass lily pipes to minimize visible equipment, keeping your aquascape pristine. HOB filters are more visible on the tank rim.
- Livestock & Plants: Gentle flow from a sponge-covered HOB is good for shrimp and bettas. Canister filters allow more flow customization, ideal for high-tech planted setups or heavy bioloads.
Quick Pros & Cons Table
| HOB Filter | Canister Filter | |
|---|---|---|
| Upfront Cost | Low – moderate | Moderate – high |
| Setup Difficulty | Very easy | Moderate |
| Maintenance Time | Minimal | More involved |
| Customization | Limited | High |
| Suitability | Best for small–mid tanks | Best for mid–large/high-tech tanks |
Which Filter Should You Choose for Your Aquascape?
For beginners, nano tanks, or aquascapes with delicate livestock, a HOB filter is affordable, quick to set up, and easy to maintain. For larger, heavily planted aquariums or when aiming for crystal-clear water and minimal visible equipment, a canister filter is a smart investment.
Remember: A great aquascape starts with excellent water quality. Choose the filtration system that best matches your tank size, aquascaping design, and your willingness to invest time and budget into regular aquarium maintenance.
Final Thoughts
Filter choice is just one piece of the puzzle. Consider how lighting, aquascape layout, and plant selection will impact your ecosystem. Planning ahead will set you up for a thriving, beautiful aquarium.
