Feeding Checklist for Tank Automation

Program automation around what each group actually needs instead of using one blanket feeding event. Active fish may need 2-4 small dry feedings daily, while LPS target feeding or broadcast coral foods might only run 2-3 times per week to avoid excess phosphate and nitrate spikes.

List which equipment must pause or change state during feeding, including return pump, wavemakers, gyres, skimmer, fleece roller, UV, and ATO. This prevents food from going straight to the overflow, skimmer cup, or filter roll before fish and corals can consume it.

Set one master trigger such as a controller feed mode, then define a backup method like a manual dashboard button or local smart plug scene. This matters when cloud services, Wi-Fi, or app access fail and you still need predictable feeding control.

Dry pellets and flakes are easiest for auto feeders, while frozen foods usually require manual prep or a refrigerated feeder solution. Coral powders, amino acids, and liquid foods often need dosing pumps or manual spot feeding because many standard feeders cannot handle moisture-sensitive foods reliably.

Use controller rules to cap feed events per 24 hours so a stuck button, duplicate schedule, or repeated cloud command cannot dump multiple servings. This is especially important on tanks with nutrient targets such as nitrate 2-15 ppm and phosphate 0.03-0.10 ppm.

Schedule fish feeding when lights are on and fish are actively cruising, and time coral feeding around polyp extension, often 30-90 minutes after lights dim for many LPS and some non-photosynthetic species. Matching natural behavior improves uptake and reduces wasted food in low-response periods.

Place the feeder away from sump vapor, open tops with strong evaporation, and skimmer exhaust. Humidity causes pellet clumping and flake bridging, which leads to underfeeding on some days and sudden overfeeding when the blockage breaks loose.

Do not trust factory dial settings alone. Dispense several test rotations into a dry container, weigh the food on a gram scale or count pellets, then average the result so each programmed event delivers a repeatable amount.

Watch where food lands during normal flow and feed mode flow. In many rimless systems, pellets can bounce into an overflow box or collect in one corner unless the feeder outlet is repositioned or a feeding ring is added.

A floating ring helps keep flakes and small pellets away from overflows long enough for fish to eat. It also makes camera-based verification easier because you know exactly where food should appear during each event.

Do not try to run moisture-prone powdered coral foods through a standard pellet drum unless the feeder is designed for it. Use dedicated dosing pumps, magnetic stirrers, or manual target feeding tools for liquids and suspensions to reduce clogs and spoilage.

If your controller reboots or a smart plug loses state after an outage, the feeder may miss events or double-run. Choose hardware that resumes schedules cleanly or document the exact restart behavior so you can compensate in programming.

A typical feed mode lasts 5-15 minutes for fish feeding, depending on overflow design and fish aggression. Too short and food is exported immediately, too long and oxygen exchange or sump circulation may suffer on heavily stocked tanks.

Set wavemakers or gyres to 10-30 percent rather than full off when possible. Gentle circulation keeps food suspended for fish and corals while avoiding dead spots where pellets sink into rockwork and decompose.

Program a 15-45 minute skimmer delay after broadcast coral foods, amino acids, or fine particulate feeds. Immediate skimming removes expensive foods before polyps can capture them and can also trigger temporary overflow from surfactants.

If you run an automatic fleece roller, pause it during and shortly after feeding so suspended food is not instantly trapped. A 10-20 minute delay is often enough for fish feeding, while coral broadcast feeds may benefit from a longer hold depending on particle size.

Turning off return or circulation can temporarily change sump water level and trigger the ATO incorrectly. Lock out ATO for the feed window if needed, and avoid scheduling alkalinity, calcium, or nutrient dosing at the same moment to reduce pH and level noise.

Fish feed mode may only pause the return and soften flow, while coral feed mode might also delay skimming and mechanical filtration longer. Using one generic mode usually leads to compromises that are not ideal for either livestock group.

A simple tank camera aimed at the feeding zone lets you confirm that food actually dispensed and fish responded normally. This is one of the easiest ways to catch empty feeder drums, bridged food, or a feeder that rotated without releasing anything.

Many missed feedings happen because the hopper runs low rather than because the feeder breaks. Use a refill reminder based on days of use or install a simple optical or weight-based check if your setup supports it.

Any increase in feed frequency or coral foods should be followed by tracking nitrate and phosphate for 1-2 weeks. If nitrate climbs above your target range or phosphate rises beyond roughly 0.10 ppm, reduce portions or increase export before algae and cyano gain momentum.

Long feed modes with reduced flow can lower gas exchange, especially overnight or in warm systems above 79-80 F. If fish gather at the surface or pH dips unusually during feeding windows, shorten pump pauses and keep some surface agitation running.

Disable or suppress expected alarms such as sump level, pump power draw, or skimmer state during the programmed feeding sequence. This reduces alert fatigue so you still pay attention when a real issue occurs outside the normal timing window.

Not all fish will transition from frozen to pellets, and some corals respond poorly to certain powdered blends. Keep notes on which fish chase, spit, or ignore foods so your automation reflects actual consumption rather than assumed intake.

Salt creep, food dust, and humidity residue change how much food drops per rotation over time. Inspect weekly and clean as needed so your calibrated portion size stays stable instead of slowly drifting upward or downward.

If your main feeder fails before a trip, shipping delays can force unsafe improvisation. Keeping a tested spare and a fresh container of the same pellet size lets you swap hardware without recalibrating from scratch.

Your manual feed button should trigger the same pump pauses and restart delays as the scheduled automation. This avoids the common mistake of hand feeding while the return, skimmer, and fleece roller are still running normally.

If someone else checks the tank, they need clear instructions on when not to add extra food because the system already fed. A printed guide with normal feed times, emergency stop steps, and what a successful feed looks like prevents accidental double feeding.

A 1 mm pellet behaves very differently from a 2 mm pellet in the same drum opening, and seasonal moisture changes can alter flow. Any food change should trigger a fresh dispense test rather than assuming the old setting still applies.

Adding anthias, wrasses, or larger tangs can change competition and required frequency overnight. Reassess portions, event timing, and flow reduction if timid fish are being outcompeted or if aggressive fish consume everything before corals get any share.
