Gravel vacuum (siphon)
Plastic tube with a wide hood + thin hose. Hover over substrate, debris siphons out with water change. Essential for gravel tanks. For sand: hover 1 cm above surface (don't plunge). Eheim, Aqueon, Fluval all reliable.

๐งน Cleaning + maintenance
Most fishkeepers quit because water changes feel like a chore. With the right tools, the weekly 30% change takes 20 minutes start to finish โ including the bucket-free Python option that's a game-changer. Here's the kit that makes upkeep sustainable.

Magnetic glass cleaners (Mag-Float) clean inside the glass without wet hands โ magnet outside drags scrubber inside. Scrapers for stubborn green spot algae. ALWAYS check no sand grain caught between magnet halves โ scratches glass instantly.
Two 10โ15 L buckets, MARKED FISH ONLY. NEVER reuse cleaning buckets โ soap residue kills fish. Buy pet-shop "fish-only" buckets or new household ones. Use one for clean dechlorinated water in, one for dirty out.
Soft mesh, sized to fish. Two nets = catching tool (use both to herd fish into one). Wet net before use (dry mesh damages slime coat). Replace at first tear. Different sizes for different fish โ tiny mesh for fry, larger for big fish.
Hose connects to your kitchen/bathroom tap โ siphons water out + refills directly from tap (with dechlor added). No buckets. 100 L water change in 10 minutes vs 45 minutes with buckets. Best maintenance tool ever invented. โฌ40โโฌ80, pays itself back in time saved.
API Master test kit. Read pH, ammonia, nitrite, nitrate. Write down. Healthy: 0/0/under 20. Anything else = adjust the routine (more water change, less feeding, filter check).
Magnet cleaner inside the glass. Algae scraper for stubborn spots. Wipe outside glass with damp microfibre. Don't need to scrub decor weekly โ only when visibly dirty.
Hold vac over substrate, siphon 25โ30% of tank water OUT into bucket / down sink. Move vac systematically over each section. Watch fish for stress (most don't care).
Bucket method: dechlorinate the bucket water (Seachem Prime), temperature-match, pour slowly back. Python method: dechlorinate the WHOLE tank for the volume going in (e.g. 30 L worth) before turning on the tap, then refill from tap.
Check filter flow. If reduced: rinse mechanical media in OLD tank water from your bucket (NEVER tap โ chlorine kills bacteria). Most weeks no action needed; once a month full mechanical-media rinse.
Once a month: deep-clean impeller (limescale), inspect heater, replace filter pre-sponge if degraded, check air pump, glance over silicone seals on tank. 5 minutes. Quarterly: empty + scrub canister filter media + chambers.
Our cleaning and maintenance tools range goes live as we vet suppliers โ we won't list anything we wouldn't use ourselves. In the meantime, our calculators, breed guides and AI vet tools below are free and don't need stock.
With buckets + gravel vac: 30โ45 minutes for a 100 L tank. With a Python tap-attached water changer: 15โ20 minutes. The Python is the single biggest time-saver in fishkeeping โ โฌ40 well spent if you have a tank over 60 L.
NEVER. Most kitchen sponges have antibacterial coatings, fragrance, or detergent residues โ toxic to fish. Use ONLY aquarium-specific magnetic cleaners, sponges, scrapers. Even "new" household sponges can have manufacturing residues.
Almost never. Fish are far less stressed by you working in the tank than by being netted out. Move slowly, avoid sudden splashes, work around them. Only remove fish for: full strip-down, heavy chemical treatment, transferring to a new tank.
Three usual causes: (1) bucket method when a Python would solve it, (2) you're scrubbing decor unnecessarily (only when visibly dirty), (3) overstocked tank requires more drastic changes โ reduce stocking. Most healthy 100 L tanks: 20 minutes start to finish, weekly.
