First Planted Tank: Complete Shopping List

Walking into a fish store for your first planted tank without a list is how you come home with the wrong light, too little substrate, and a "bargain" filter that won't cut it — then make three more trips. This is the complete first planted tank shopping list: everything you need, nothing you don't, organized by priority, with what to buy quality and where it's safe to save.

How to Use This List

Items are grouped into essential (the tank doesn't work without it), highly recommended (buy now, thank yourself later), and skip for now (common upsells you don't need yet). Budget guidance assumes a 10–20 gallon first tank — scale quantities up for larger builds using our size guides: 10-gallon setup, 20-gallon setup, 40-gallon breeder.

Essential: The Tank Itself

• Aquarium (10 or 20-gallon long recommended) — the 10-gallon is cheapest to equip; the 20-long is more forgiving. Buy the tank with a glass lid or lid set — open tops evaporate fast and fish jump. If the kit includes a lid, great; otherwise add one.
• Stand or sturdy furniture — a filled 10-gallon weighs ~110 lbs, a 20-long ~225 lbs. Dedicated aquarium stands are cheapest insurance; solid wood dressers work if level and strong. Particle-board furniture is a flood waiting to happen.

A 10-gallon starter kit bundles tank, light, and filter for a first build: Aqueon 10-gallon aquarium starter kit.

Essential: Lighting (Buy Quality Here)

• Planted-tank LED fixture, full length of the tank — this is the single most impactful purchase. A proper planted LED (full-spectrum, ~6500K) grows plants; the dim kit light in all-in-one boxes grows algae and disappointment. Size the fixture to the tank length (20" for 10-gallon, 30" for 20-long).
• Outlet timer plug — non-negotiable. Consistent 7–8 hour photoperiods prevent algae; human-switched lights never stay consistent. A basic mechanical timer costs little and is the best algae prevention you can buy.

Where to save: skip Bluetooth/app-controlled lights for now — the timer plug does the job. Where not to save: the fixture itself. A weak light is the number-one reason first planted tanks fail.

The one place never to skimp: a full-spectrum planted-tank LED you can dim and tune: Fluval Plant 3.0 LED.

Essential: Filtration

• Hang-on-back filter rated for your tank size — simple, effective, cheap. For 10–20 gallons, one HOB rated at or slightly above tank volume is plenty.
• Pre-filter sponge — fits over the intake tube; protects shrimp, fry, and betta fins, and adds biological capacity. A few dollars that prevents real losses.
• Filter media — most HOBs include adequate media; add a bag of ceramic bio-media if yours is cartridge-only (cartridges are a recurring-cost trap — switch to reusable sponge + bio-media).

Alternative: a sponge filter + air pump — the cheapest filtration that works, ideal for shrimp or betta tanks. Our planted shrimp tank setup uses this approach.

A hang-on-back filter with adjustable flow is the beginner workhorse: AquaClear 20 power filter.

Essential: Heating and Monitoring

• Adjustable heater (50W for 10-gal, 100W for 20-gal) — adjustable, not preset. Preset heaters are inaccurate; adjustable with a thermostat holds temperature properly.
• Thermometer — a simple stick-on or glass thermometer. You can't manage what you don't measure.
• Liquid test kit (ammonia, nitrite, nitrate, pH) — the API-style master kit. Test strips are inaccurate; the liquid kit lasts a year and is the difference between guessing and knowing during the cycle. Our water parameters guide explains what the numbers mean.
• Water conditioner (dechlorinator) — treats tap water's chlorine/chloramine. One bottle lasts months.

Essential: Substrate

• Aquasoil (one 9L bag for 10–20 gallons) — the beginner-friendly choice: feeds plants for months, buffers pH gently, grows everything. One bag does a 10-gallon generously or a 20-long at 2 inches.
• Budget alternative: inert sand or gravel + root tabs — cheaper, works fine, just add root tabs under heavy root feeders and liquid fertilizer from the start.

A nutrient-rich aquasoil that feeds plants from day one: Fluval Plant and Shrimp Stratum.

Essential: Plants (Buy Heavy, Buy Once)

Buy 70%+ coverage on day one — sparse planting is the top beginner mistake. A starter plant order for a 10–20 gallon:

• Background stems (2–3 bunches): rotala, bacopa, ludwigia — fast growers that establish quickly
• Epiphytes (3–5 portions): anubias nana, java fern — tie to wood/rocks; indestructible
• Midground (3–4 pots): cryptocoryne wendtii — the beginner's best friend
• Foreground/carpet (2–4 pots): dwarf sagittaria or Monte Carlo
• Floating plants (one portion): frogbit or salvinia — instant algae-fighting shade
• Moss (one portion): java moss for wood and corners

Our planting quantity guide refines these numbers. Buy from a reputable online seller or local hobbyist — store plants are often half-melted. Tissue-culture cups cost more but arrive pest-free.

Essential: Hardscape

• One driftwood piece (sized to your tank) or 3–5 small stones — one focal hardscape element, not a rock collection. Malaysian driftwood and dragon stone are the safe classics.

Highly Recommended (Buy With the First Order)

• Aquascaping tweezers (long, curved tip) — planting without them in a filled tank is misery; with them it's precision. The single best tool purchase.
• Aquascaping scissors (curved) — trimming with kitchen scissors mangles stems; proper scissors make clean cuts that heal fast.
• Comprehensive liquid fertilizer — one bottle; with aquasoil you won't need it for 2–3 months, with inert substrate from day one. Buy it now so it's on hand.
• Root tabs — for swords and crypts in any substrate; cheap, last months.
• Algae scraper or magnetic cleaner — you'll need it within weeks; buy before you do.
• Small siphon/gravel vacuum — sized to your tank; water changes without one are miserable.
• Bucket (dedicated, never used with soap) — 2–3 gallons for a 10-gallon, 5 gallons for a 20-long.
• Fish net (small, soft mesh) — for the inevitable plant-trim rescues and eventual stocking.

Livestock (After Cycling — Not on Day One)

Don't buy fish with the setup. Cycle first (our faster cycling guide), then stock gradually. When ready, proven first-tank livestock:

• Cleanup crew first: 3–4 otocinclus or 5–10 cherry shrimp + 2–3 nerite snails
• School: 8–10 ember tetras, chili rasboras, or neon tetras — our schooling fish guide compares them
• Centerpiece (20-gallon): 1 honey gourami or a pair of German blue rams
• Centerpiece (10-gallon): 1 betta — our planted betta tank setup

Skip for Now (Common Upsells)

• CO₂ system — wonderful later, unnecessary now. Master low-tech first; our low-tech guide proves what's possible without it.
• UV sterilizer — solves problems you shouldn't have yet; proper balance prevents green water.
• pH adjusters and "buffer" chemicals — cause the swings they claim to fix. Stable tap water beats chemically manipulated water.
• Specialty substrates additives, bacterial "cycle in a bottle" miracles — some help marginally; none replace the actual cycle.
• Expensive aquascaping rock sets — one good wood piece beats five mediocre stones.
• Automatic feeders, dosers — automation for a tank you're learning to read is premature.

The Shopping Strategy

1. Order hardware online — lights, filters, heaters, substrate: better prices and selection than most stores.
2. Buy hardscape in person if possible — wood and stone are character pieces; choosing in person matters.
3. Order plants to arrive the day you set up — plant the same day they arrive; don't let them sit.
4. Set up, plant, cycle — then buy fish locally after watching the tank mature. Never buy livestock on setup day.
5. Keep receipts and boxes for 30 days — heaters and filters have meaningful defect rates; the return window matters.

Frequently Asked Questions

What's the minimum budget for a proper first planted tank?

A 10-gallon planted setup with quality light, decent filter, heater, aquasoil, plants, and basic tools is genuinely affordable — the light and plants are the big line items. The 20-long costs roughly 50% more to equip but is more forgiving. Either way, the "buy quality light, buy heavy plants" rule holds: skimping on those two is the false economy that kills first tanks.

Should I buy an all-in-one kit or piece it together?

Piece it together. All-in-one kits bundle weak lights, cartridge filters (recurring cost trap), and preset heaters — the three components most worth choosing properly. The kit's only advantage is convenience, and it costs you in upgrades within months. Buy the tank + lid as a box, choose everything else individually from this list.

Where's the best place to buy aquarium plants?

Reputable online aquatic-plant sellers and local hobbyist groups beat chain pet stores on health, variety, and price. Tissue-culture cups (pest-free, dense) are worth the premium for foregrounds. Local aquarium club auctions are the hobby's best-kept secret — healthy, cheap, locally adapted plants.

Do I really need the test kit? Can't I just wait a month?

The test kit is how you know the cycle is done instead of hoping. "Wait a month" works only if the cycle actually completed — and without testing, you can't distinguish a cycled tank from a stalled one. The liquid kit costs little, lasts a year, and prevents the number-one beginner disaster: stocking an uncycled tank.

What can I skip if money is really tight?

Buy used tanks and filters (leak-test tanks outdoors first), choose sand + root tabs over aquasoil, get plant trimmings from hobbyists free or cheap, and skip the aquascaping tools initially (tweezers first when you can). Never skip: the light quality, the test kit, the heater (for tropicals), or the dechlorinator. Those four are safety-critical.

When do I buy the fish?

After the tank is cycled and plants are growing — typically 2–4 weeks after setup, verified by zero ammonia/nitrite readings for a week. Buying fish on setup day is the classic beginner error; the empty planted tank is not a failure, it's the process working. Patience now prevents losses later.

The List, Condensed

Tank + lid + stand. Quality planted light + timer. HOB filter + pre-filter sponge. Adjustable heater + thermometer. Liquid test kit + dechlorinator. Aquasoil. Heavy plant order. One wood piece. Tweezers, scissors, fertilizer, root tabs, scraper, siphon, bucket, net. Cycle, then livestock. That's the complete first planted tank — everything on this list earns its place, nothing here is filler. Print it, shop it, build it.
