Starting Your First Reef Tank: What You Need to Know

Thinking about starting your first reef tank? You’re not alone! Reef tanks—those beautiful saltwater aquariums filled with colorful fish and live corals—are a dream for many aquarium lovers. But let’s be honest: they do take some work.

Good news? You don’t have to do it alone. With the ReefKG app (coming soon!), you’ll be able to track and manage your aquarium chemicals with ease, helping you maintain a healthy, thriving tank with less stress.

Let’s break it down and show you how to get started—and how ReefKG will make it even easier!

Why a Reef Tank?

A reef tank is more than just a salt water aquarium—it’s a living, underwater world. You can keep saltwater fish, corals, and other sea life that you won’t find in freshwater fish tanks. The colors, the movement, the peaceful vibe—it’s truly something special.

However, reef tanks need more care than your average fish tank. You’ll need to keep track of things like salinity, calcium, and magnesium dosing, plus do regular aquarium water changes. That’s where the ReefKG app can help—by reminding you what to do, when to do it, and how much to dose.



What You’ll Need to Get Started

Pick the Right Tank Size

If you’re new to saltwater tanks, something like a 30 gallon fish tank, 40 gallon tank, or 55 gallon fish tank stand is a great start. Use a fish tank calculator or aquarium capacity calculator to make sure your fish and corals have enough space. The ReefKG app will include a built-in tank calculator and reef dosing calculator, so no need to stress about the math.

Add the Right Equipment

You’ll need:

  • A good fish tank filter

  • Strong lighting (for coral growth)

  • A heater (to keep your saltwater aquarium at the right temp)

  • Live rock and sand (for natural filtration)

Once it’s all set up, the tank should cycle for a few weeks before adding any fish or corals. Patience is key!

Keeping Your Reef Tank Healthy

Know Your Water Parameters

To keep your reef tank happy, you need to watch your water chemistry closely. Important reef tank parameters include:

  • Salinity

  • pH

  • Temperature

  • Calcium

  • Alkalinity

  • Magnesium

Sounds like a lot? That’s why we created ReefKG. This app (coming soon!) will track all your chemical levels and tell you when it’s time for a change or dose. No more guessing!

Do Regular Maintenance

Just like any pet, your reef needs love and care. That includes:

  • Weekly or bi-weekly aquarium water changes

  • Checking your filters

  • Cleaning the glass

  • Testing your water

If that sounds like too much, don’t worry—there are plenty of aquarium cleaning services and fish tank maintenance service near me you can hire. But with ReefKG, you may find you can handle a lot more on your own.

Avoid These Common Beginner Mistakes

It’s easy to get excited and rush things, but here are a few things to avoid:

  1. Adding fish too soon (let the tank cycle first)

  2. Skipping water tests

  3. Overfeeding

  4. Using tap water instead of RO/DI

  5. Not keeping up with aquarium maintenance

The ReefKG app will help you avoid these mistakes by keeping track of your schedule and sending you simple reminders. Think of it as your personal reef tank maintenance assistant in your pocket.
