Aquatics & Aquarium is Talis-us's dedicated hub for fishkeeping enthusiasts — from beginners setting up their first community tank to advanced hobbyists maintaining complex planted aquascapes and saltwater reef systems.
The aquarium hobby is one of the most visually captivating and scientifically rich hobbies available today. A well-maintained aquarium is a living ecosystem — a precisely balanced interplay of water chemistry, biology, lighting, and livestock that rewards patience and skill with results that are genuinely stunning.
But the hobby is littered with bad products, outdated advice, and undersized starter kits that set beginners up to fail. At Aquatics & Aquarium, every product carries the Talis Curated badge — vetted for water safety, equipment reliability, and genuine keeper value. Whether you're cycling your first tank, building a CO2-injected planted aquascape, or assembling a reef-ready system, this is your curated starting point.

❓ Aquatics & Aquarium — FAQ
Q1: I'm completely new to fishkeeping. Where do I start?
Start with a freshwater community tank of at least 20 gallons — larger tanks are more forgiving for beginners because water parameters stay stable longer. You'll need: a tank, a filter rated for your tank size, a heater (for tropical fish), a thermometer, a liquid water test kit, a water conditioner, and appropriate substrate. Set up and fully cycle the tank before adding any fish. Our freshwater starter guides walk you through every step.
Q2: What is the nitrogen cycle and why does it matter?
The nitrogen cycle is the biological process by which beneficial bacteria convert toxic fish waste (ammonia) into nitrite, then into the far less harmful nitrate. A tank that hasn't completed this cycle — typically 4–8 weeks — will produce ammonia and nitrite spikes that are lethal to fish. Always cycle your tank before adding livestock. Use a liquid test kit (not strip tests) to monitor ammonia, nitrite, and nitrate throughout the process.
Q3: Freshwater or saltwater — which is right for me?
-
Freshwater is significantly easier to maintain, less expensive to set up, and offers a vast range of fish and plant options. Ideal for beginners and aquascapers.
-
Saltwater (FOWLR) is more demanding in water chemistry but opens up an extraordinary range of marine fish. Requires more precise equipment and regular testing.
-
Reef tanks are the most complex and expensive — maintaining corals requires stable salinity, alkalinity, calcium, and magnesium alongside lighting precision. Recommended for keepers with at least one year of prior fishkeeping experience.
Q4: How often do I need to do water changes?
For most freshwater tanks, a 25–30% water change weekly is the standard recommendation. Heavily stocked tanks may need more frequent changes; lightly stocked tanks with strong filtration may manage bi-weekly. For saltwater and reef systems, weekly 10–20% water changes help replenish trace elements. Always treat new water with a dechlorinator before adding it to the tank.
Q5: Do I need live plants in my freshwater aquarium?
Live plants are not required, but they offer significant benefits: they consume ammonia and nitrate (improving water quality), produce oxygen, outcompete algae for nutrients, and provide natural shelter for fish. For beginners, low-tech species like Java fern, Anubias, and Cryptocorynes thrive without CO2 injection or high-output lighting. A planted tank is one of the most rewarding setups in the hobby.
Q6: What water parameters do I need to monitor?
Key parameters for freshwater tanks:
-
Ammonia: 0 ppm (any detectable amount is harmful)
-
Nitrite: 0 ppm (toxic even at low levels)
-
Nitrate: Below 20–40 ppm for most fish
-
pH: Species-dependent (most community fish: 6.8–7.6)
-
Temperature: Species-dependent (tropical fish: 74–80°F)
Saltwater and reef systems additionally require monitoring of salinity (1.024–1.026 SG), alkalinity, calcium, and magnesium. Always use a liquid test kit — strip tests are inaccurate.
Q7: How do I control algae in my tank?
Algae is a symptom of imbalance, not a disease. Common causes include excess light duration, elevated nitrates or phosphates, and inconsistent water changes. Solutions include: reducing light to 6–8 hours per day, increasing plant density to outcompete algae for nutrients, adding algae-eating species (Otocinclus, Amano shrimp, Nerite snails), and maintaining a consistent water change routine. Avoid chemical algaecides — they treat symptoms and can harm livestock.
Q8: What is a planted tank and do I need CO2?
A planted aquarium incorporates live aquatic plants as a core element of the setup. CO2 injection is not required for low-tech planted tanks using slow-growing, low-light species like Anubias, Java fern, and mosses. High-tech setups with demanding stem plants and carpeting species benefit significantly from pressurized CO2 systems, which accelerate growth and prevent nutrient deficiencies. Our planted tank guides help you choose the right approach for your goals and budget.
Q9: Can I keep shrimp with fish?
Yes, with careful species selection. Most fish will eat small shrimp. Safe tank mates include: Otocinclus catfish, small Corydoras, Ember tetras, and Chili rasboras. Avoid cichlids, bettas, and any fish with a mouth large enough to swallow a shrimp. Dense planting significantly improves shrimp survival. For dedicated breeding colonies, a species-only shrimp tank is the most reliable approach.
Q10: What makes Aquatics & Aquarium different from a generic pet store?
Pet stores stock for volume — not keeper success. Undersized filters, inaccurate strip test kits, and inadequate lighting are sold alongside fish without compatibility guidance or care context. At Aquatics & Aquarium, every product is Talis Curated — vetted for water safety, equipment reliability, and genuine hobbyist value. We include species compatibility charts, cycling guides, and water parameter references with every purchase, because a thriving tank is the best product we can offer.
