Questions to ask before hiring an aquarium maintenance company.

1. What types of aquariums do you service?

Ask whether they work with:

• Freshwater tanks
• Saltwater fish-only tanks
• Reef tanks with coral
• Planted tanks
• Office or commercial displays
• Custom aquariums
• Large tanks

A company that handles simple freshwater tanks may not be the right fit for a demanding reef system.

2. What is included in each visit?

Get a clear list. A visit may include water changes, glass cleaning, gravel or sand cleaning, filter maintenance, skimmer cleaning, testing, and equipment inspection. If the quote is vague, ask for a written service checklist.

3. Do you test water parameters?

For saltwater and reef aquariums, testing matters. Ask which parameters they test and how often. Common reef tests include salinity, alkalinity, calcium, magnesium, nitrate, and phosphate.

4. Are supplies included?

Ask whether the price includes:

• Saltwater
• RO/DI freshwater
• Filter media
• Carbon
• Dosing supplements
• Replacement parts
• Test kits

This prevents surprises after the first visit.

5. How often should my tank be serviced?

A good provider should recommend a schedule based on tank type, size, livestock, condition, and your ability to handle tasks between visits. Be cautious if every tank gets the same answer.

6. Do you provide emergency support?

Ask what happens if a pump fails, a tank leaks, a fish dies, or water quality crashes. Not every company offers emergency service, but you should know the options before something goes wrong.

7. Are you insured?

Aquariums involve water, electricity, glass, livestock, and sometimes expensive property. For home and commercial service, insurance is a serious trust signal.

8. Do you leave notes after service?

Good visit notes may include:

• What was done
• Water parameters
• Livestock observations
• Supplies used
• Recommended next steps
• Equipment concerns

Notes help you track the tank over time.

9. Can you handle upgrades or installation?

If you may need a new sump, lighting, auto top-off, dosing system, or custom aquarium, ask whether the company handles installation or only routine cleaning.

10. Can you provide references or examples?

Photos, reviews, and references help show whether the company has experience with tanks like yours.

Bottom line

The best aquarium maintenance company is not just the cheapest cleaner. Look for clear communication, experience with your type of tank, water testing, equipment awareness, insurance, and a maintenance plan that matches your aquarium's needs.
