When maintained properly, your fountain becomes more than a visual feature. It becomes a symbol of your community’s commitment to quality, care, and environmental stewardship.
If you're reading this, you probably just lost some fish. Or maybe you're setting up a new tank and someone warned you about using tap water straight from the faucet. Either way, you're asking the right question. The short answer? Yes, city water can absolutely kill minnows and other fish. But it's not because your water department is trying to poison your pets. It's because the same chemicals that keep your drinking water safe can be deadly to fish. The good news is it's completely preventable once you understand what you're dealing with. Why City Water Is Dangerous for Fish Your municipal water supply contains chemicals that fish simply can't handle. The biggest culprit is chlorine, but it's not the only problem. Chlorine and Chloramines Every city adds chlorine to kill bacteria and make water safe to drink. Some cities use chloramines instead – a combination of chlorine and ammonia that lasts longer in the water system. Both will burn your fish's gills and kill them quickly. Minnows are especially sensitive because they're small and have a high surface area relative to their body weight. What might just stress a larger fish will kill a minnow in minutes. Heavy Metals Your pipes, especially older ones, can leach copper, lead, and other metals into your water. Fish absorb these through their gills and skin. Even tiny amounts that won't hurt you can poison fish over time. pH Problems Most city water has a pH between 7.5 and 8.5 to prevent pipe corrosion. Many fish, including most minnows, prefer slightly acidic water around 6.5 to 7.0. The wrong pH stresses fish and makes them vulnerable to disease. Chemical Additives Cities various chemicals to the water for treatment. Fish simply weren't made to handle any of these synthetic compounds. How Fast Can City Water Kill Minnows? Minnows can die in under 30 minutes in heavily chlorinated water. But even if the chlorine doesn't kill them immediately, it damages their gills permanently. Damaged gills can't extract oxygen properly, leaving your fish struggling to breathe. They become sitting ducks for infections and other problems. Signs Your Fish Are Suffering from Bad Water Watch for these warning signs: Fish gasping at the surface Red or inflamed gills Lethargic behavior or lying on the bottom Loss of appetite White patches on skin or fins Fish dying with no obvious cause If you see any of these symptoms after adding new water, your water quality is probably the problem. Quick Fixes That Actually Work Dechlorinator Products The fastest solution is a good dechlorinator. Add it to your water before putting fish in. Most work in minutes, but read the label – some take longer to neutralize chloramines. Don't cheap out here. A $10 bottle of quality dechlorinator can save hundreds of dollars worth of fish. Let It Sit Chlorine will evaporate if you let water sit for 24-48 hours in an open container. This doesn't work for chloramines, though, and it doesn't remove heavy metals or fix pH problems. Boiling Boiling water for 15-20 minutes removes chlorine and chloramines, but it's not practical for large amounts. Plus, you'll need to let it cool completely before using it. Better Long-Term Solutions If you're serious about keeping fish healthy, treating your water properly from the start makes more sense than constantly fixing problems. Carbon Filtration A good carbon filter removes chlorine, many chemicals, and some heavy metals. It won't fix pH problems, but it's a solid first step. Replace the carbon regularly – old carbon stops working. Reverse Osmosis Systems RO systems remove almost everything from water, giving you a clean slate to work with. You'll need to add back minerals for fish health, but you control exactly what goes in. This is what we recommend for serious fish keepers. Yes, it's more expensive upfront, but you'll save money on fish replacements and medications in the long run. Water Conditioners Good conditioners do more than just remove chlorine. They neutralize heavy metals, reduce stress, and protect fish's slime coat. Use them every time you add new water. Testing Your Water You can't fix what you don't measure. Get test strips or a digital meter to check: Chlorine levels (should be zero for fish) pH (most freshwater fish prefer 6.5-7.5) Ammonia and nitrites (both should be zero) Hardness (depends on your fish species) Test your tap water and your tank water separately. Sometimes the problem is in your tank, not your source water. What About Well Water? Well water isn't automatically better for fish. It can have high iron, hydrogen sulfide, or other problems that city water doesn't have. Contact us to get your well water tested before using it in your tank or learn about our water conditioning services . An Honest Recommendation If you just need to save some minnows right now, grab a bottle of dechlorinator from any pet store. Follow the directions exactly – more isn't better. But if you want to keep fish long-term and avoid these problems, invest in proper water treatment. Too often, people spend hundreds on fish and equipment, then lose everything because they skipped water treatment. A basic carbon filter costs less than replacing a tank full of dead fish. An RO system costs less than the medications and fish you'll buy trying to fix problems caused by bad water. When to Call for Help Some water problems are too complex for DIY solutions. If you're dealing with: Extreme pH levels (below 6.0 or above 9.0) High levels of heavy metals Complex chemical contamination Multiple fish tanks with different needs You need professional water treatment. We've solved problems that killed fish for months, and the solution is usually simpler than people think. The Bottom Line City water can definitely kill minnows, but it doesn't have to. The chemicals that make your water safe to drink are poison to fish. Remove those chemicals, and your fish will thrive. Don't gamble with the lives of your fish. Treat your water properly from day one, test regularly, and call us when you're in over your head. Your fish are counting on you to get this right. Good water is the foundation of everything else in fishkeeping. Get the water right, and most other problems solve themselves.
Is Tap Water Really Safe? If you’re a Naples homeowner wondering whether your family should drink water straight from the tap or invest in a filter, you’re not alone. Every day, millions of people use city water to cook, clean, and stay hydrated—but many still wonder: Is it safe? And more importantly, is it clean enough for my kids? This guide breaks it all down in simple terms. You’ll learn how the city treats water, what might still be in it, and how to decide if a filter is worth it. How City Water Is Treated Naples city water goes through several steps at a treatment plant to make it clean and safe: 1. Collection Water is pulled from lakes, rivers, or groundwater sources. 2. Coagulation and Flocculation Chemicals are added to help dirt and particles clump together. 3. Sedimentation The clumps settle at the bottom of a tank and are removed. 4. Filtration The water passes through sand, gravel, and charcoal filters to catch smaller particles. 5. Disinfection Chlorine, ozone, or UV light is used to kill bacteria and viruses. Once treated, water travels through underground pipes to your home. In most U.S. cities, this system is regularly tested and meets federal safety rules. What’s Still in Tap Water After Treatment? Even though tap water is treated, small amounts of other things can still be present. These aren’t always dangerous, but they can be a concern—especially for sensitive groups like kids, older adults, or those with health conditions. Here’s what might still be in your tap water: Chlorine: Used to kill germs, but can leave a strong taste or smell. Lead: Can enter water from old pipes, especially in homes built before 1986. PFAS (“Forever Chemicals”): Man-made substances used in non-stick pans and waterproof clothes. They’re hard to remove and may affect health over time. Microplastics: Tiny bits of plastic from bottles or clothes that end up in water. Nitrates: Often from fertilizers; risky for babies and pregnant women. Not every home has these in their water—but it's possible. Water quality can also vary by city, season, and even neighborhood. When You Should Consider Filtering Not everyone needs a water filter—but in some situations, it’s a smart move. Here are signs that a filter could help: You live in an older home: Homes built before 1986 may have lead pipes or fixtures. You don’t like the taste or smell: Filters can improve chlorine-heavy or “metallic” water. You’re pregnant or have young kids: Extra protection never hurts when your immune system is more sensitive. Your city has had water safety violations: If there’s been a past issue (like lead, bacteria, or PFAS), using a filter is wise. You use a private well: These aren't treated by the city and should always be tested and filtered if needed. Want to be sure? Start by ordering a free water quality report from your local water provider or visiting the EPA's Consumer Confidence Report tool . How to Check Your Water Quality You don’t need to become a water expert to know if your home’s tap water is safe—we’re here to help with that. Instead of digging through reports or buying test kits, contact us for a personalized water review . We can help you understand what’s in your local water supply, what it means for your home, and whether a filter could make a difference. We’ve reviewed water quality reports across hundreds of cities and can give you clear, honest advice—without the confusion. Bottom Line: Should You Filter Your Tap Water? So, what’s the final answer? If you trust the Naples water system and don’t have old pipes, your tap water is probably safe to drink. The EPA sets strict rules, and most U.S. cities follow them. But that doesn’t mean it’s perfect. Filtering can remove leftover chemicals, metals, and bad taste—giving you cleaner, fresher water and peace of mind. It’s especially helpful if: You have kids or elderly family members at home You’ve had plumbing problems or live in an older house You simply want better-tasting water Think of a filter as a booster—not a must-have for everyone, but a smart step if you want extra protection.
