Aquarium Maintenance

What they do

A typical visit follows a steady rhythm: observe every animal first, then test the water, then work. Technicians check temperature, pH, ammonia, nitrite, and nitrate, plus salinity for marine tanks and hardness where it matters for the species kept. Results are compared with previous visits, because a slow drift in nitrate or pH is often the earliest sign that feeding, stocking, or filtration has slipped out of balance.

Physical work includes partial water changes with dechlorinated or properly mixed salt water matched for temperature, algae removal from glass and decor, siphoning waste from substrate, rinsing or replacing filter media in a way that protects beneficial bacteria, and cleaning pumps, skimmers, and lights. Media is never all replaced or scrubbed in tap water at once — that would strip the bacteria the cycle depends on.

Technicians also act as an extra set of trained eyes. They note fish that are hiding, not eating, breathing fast, or showing spots or frayed fins, trim plants, check heater and pump performance, and flag equipment that is aging before it fails on a holiday weekend. They will advise on feeding amounts and new purchases, and may refuse to add livestock to a tank that is not stable.

Unlike installation, this is an ongoing relationship measured over months. Unlike holiday-only aquatic care, maintenance includes water chemistry, equipment servicing, and long-term stocking advice — not just feeding while you are away.

Services you can expect

• Scheduled water testing with written results
• Partial water changes and top-offs
• Algae cleaning and substrate siphoning
• Filter, pump, and protein skimmer servicing
• Health and behavior checks on all livestock
• Plant trimming and decor cleaning
• Feeding review and stocking advice
• Equipment replacement and emergency call-outs
• Livestock sourcing and acclimation on request

What to expect

• A service log each visit with test results, work done, and anything to watch
• Water matched for temperature and, for marine tanks, salinity before it goes in
• Filter bacteria protected — media handled gently and never all replaced at once
• Honest advice when a tank is overstocked or a new purchase would be unwise
• Floors and furnishings left dry and tidy, with equipment restarted and checked

How to choose

• Pick a service that keeps tanks like yours — a reef specialist and a planted-tank specialist use different skills
• Ask what is tested at every visit and whether you receive the results in writing
• Check visit frequency matches your tank's stocking and feeding load
• Ask who covers when your regular technician is away
• Look for willingness to say no to extra livestock when water quality says wait

Questions to ask

• What tests do you run at each visit, and will I see the results?
• How do you protect filter bacteria when you clean or change media?
• How often do you recommend visiting a tank of my size and stocking?
• What do you do if you find a sick fish or a failing heater?
• Do you supply water, salt, and replacement media, or do I?
• Is there an emergency arrangement between scheduled visits?

Red flags

• No water testing, or results never recorded or shared
• Large, infrequent water changes used to rescue neglected tanks as a routine
• All filter media replaced at once or washed under a hot tap
• Pushing new fish sales at every visit regardless of test results
• Equipment left unplugged, heaters unset, or lids open after a visit

What affects the price

• Tank volume and number of tanks serviced
• Freshwater versus marine or reef complexity
• Visit frequency and travel distance
• Stocking level and feeding load
• Water, salt, media, and replacement parts supplied
• Emergency call-out cover between visits
