Reef Tank First Month Routine Guide: Daily Checks

The first thirty days of a new reef decide whether the system cruises for a decade or limps through algae blooms for a year. This reef tank first month routine guide from Gensou Aquascaping at 5 Everton Park walks SG reefers through the daily, twice-weekly and weekly touches that build a stable, cycled saltwater system. Two decades of setups in our workshop have taught us one truth: small, consistent, logged actions beat heroic weekend interventions every time.

Why Month One Matters

Between days one and thirty, your biofilter population multiplies roughly a million-fold, your live rock releases detritus and your display glass hosts a succession of diatom, cyano and green-film stages collectively called the ugly phase. Rushing this phase with corals or heavy feeding crashes parameters. Patience and observation cost nothing and prevent a $400 livestock setback.

Daily Five-Minute Walk-Past

Every morning, before the lights ramp up, spend five minutes looking. Is the skimmer producing? Is the return pump steady? Any new fish breathing heavily? Temperature on the controller should read 25-26°C — a 30°C ambient Singapore flat will push a lidless tank to 28°C without a chiller, and evaporation accelerates fast at 29°C. Top off auto-top-up (ATO) reservoirs with RODI water; a nano 30-gallon evaporates roughly 1-2 L a day in SG humidity.

Parameter Testing Cadence

Week one, test ammonia and nitrite daily until both read zero for three consecutive days. A Red Sea Pro Multi kit runs SGD 180-280 locally and covers the core suite; Salifert individuals work if you already own some. From week two, move to every other day for nitrate and alkalinity. By week four, weekly is sufficient for alkalinity, calcium and magnesium. Log every reading in a notebook or Reef Moonshiners app — drift is only visible across time.

First Livestock — Cleanup Crew Only

Around day 14-21, once ammonia and nitrite flatline, add a modest cleanup crew. For a 30-gallon (~115 L) nano: five Trochus snails (SGD 4-6 each at Iwarna or Pinnacle), three Nassarius and two peppermint shrimp. Skip hermits early — they snack on snails. Diatoms peak around day 10-20 and Trochus grazing is the cheapest control. Resist adding fish until week four minimum.

Feeding and Nutrient Management

No fish means no feeding for the first fortnight. When the first pair of fish arrive around day 28-30, start with a pinch once daily — roughly what they can eat in 30 seconds. Overfeeding is the single most common new-reefer mistake and drives the phosphate spikes that fuel cyano. A cheap GFO reactor with Rowa phosphate remover (SGD 25/kg at Singapore outlets) is insurance if phosphate climbs above 0.1 ppm.

Skimmer Break-In

A new protein skimmer takes 10-14 days to pull consistent dark skimmate. Do not keep tuning it daily — set the water level cup and leave it. Wipe the neck every three days with a microfibre cloth. Singapore humidity means skimmer cup lids sweat and overflow; tilt the cup slightly toward the tank or fit a drain line into a waste bucket. Expect roughly 100-200 mL of darker-than-coffee waste per week by month-end on a lightly stocked 30-gallon.

Lighting — Ramp Slowly

Resist the showroom instinct to run LEDs at 100 per cent. For month one, 30-40 per cent peak intensity for six hours is plenty. Full spectrum light feeds algae as effectively as corals, and you have no corals yet. Save the bulb hours and your electricity bill — a 90-watt AI Prime or Nanobox running six hours instead of ten saves roughly SGD 3-4 a month at 0.32/kWh.

Weekly Water Change Routine

From day seven onward, a 10 per cent weekly water change with properly mixed saltwater (Red Sea Blue Bucket or Tropic Marin, 1.025 SG, 25°C) replaces trace elements and exports detritus. Mix salt at least four hours before use — dumping fresh mix straight in causes pH swings. An RODI unit (SGD 180-350) pays for itself against bottled RODI at SGD 1.20/L within two months on a 30-gallon.

Pest and Algae Watch

Flatworms, aiptasia, vermetids and bryopsis hitchhike on uncured live rock. Check the back glass weekly with a torch. Aiptasia spotted early takes one drop of Aiptasia-X (SGD 45 a bottle) to eliminate; a month-old colony needs a peppermint shrimp team and patience. Cyano around week three is normal; resist antibiotics and address the cause — flow dead spots and excess phosphate.

End-of-Month Review

On day 30, review your log. Ammonia and nitrite should read zero. Nitrate 2-10 ppm, phosphate 0.02-0.08 ppm, alkalinity 8-9 dKH, calcium 420-440, magnesium 1300-1400, SG 1.025. If numbers are stable and the cleanup crew looks active, the tank is ready for its first two or three easy fish — a pair of clowns and a yellow watchman goby are classic choices. A disciplined reef tank first month routine guide approach sets the foundation for every coral you will ever add.
