Anemone In A Fish-Only Saltwater Aquarium? 9 Steps To Change Water Of Fish Tank (2022)

I have heard it is left to slightly more experienced aquarists to have coral in their saltwater aquariums, but I was interested in starting a saltwater aquarium with anemones. Is it easier/ just as difficult to take care of anemones in a saltwater tank with some fish in it? (the usual clown or two and some damsels) Do you need the same equipment as a tank with coral?

Here are some products that may help maintaining a healthy salt water tank.

Best Water Concentration Testing Strips

Easy to read – This is definitely the way to go and I can test whenever I like without worrying about wasting money. They are really accurate, but you have to make sure that you do not move the stick because they bleed onto the other testing squares pretty easily.

Do You Need A Salt Water Heater?

Good Heater – The built-in display on the actual heater is very useful. It also has a controller that I attached to the side of the tank to make adjustments as needed.

Best Aquarium Filter

Perfect filter and customisation-friendly – TI love this unit! I was able to do a minimal customization to allow this unit to hang on the side of my 55 gallon tank! It’s small yet large enough to keep the tank clean. Perfect for filter modifications! 

Keeping your water clean and fresh is a great way to ensure that your saltwater fish stay healthy and colorful. But it must be done correctly or else it can actually stress the fish out and possibly cause disease to set in. The article below will go over how to change water in a saltwater aquarium the right way.

Have a container that will only hold saltwater.

This will eliminate the possibility of using a container that had potentially toxic chemicals in it that could kill or sicken your fish.

Mix your saltwater up in the container.

Mix with a small aquarium powerhead for 24 hours.

Letting it mix for at least 24 hours will ensure that all the chemicals dissolve and the properties of the water equalize. It will also allow any ammonia that can occur when mixing new salt to dissipate.

Have a heater in the water

Make sure you set a heater within two degrees of your main tank.

Mix the replacement water.

It will make exactly the same salinity as your display tank.

Shut off all equipment including the heater.

If not, an unsubmerged heater may turn on and get hot. When the colder aquarium water touches it, it could shatter!

Siphon the old tank water out.

By doing so, you are making sure to vacuum the gravel bed to remove settled debris or if you have live rock try and remove any settled debris from it. A good way to do this is to take a small powerhead and blow the rock off just before you drain the water from your aquarium.

Pour the new water in slowly.

We emphasize “slowly” to make sure to not disturb the tank’s decorations or gravel too much.

Change filter pads or material for a fresh start.

Try and change at least 25% of your tank’s water every month and split it up into two or three smaller changes rather than one large one. This will lessen the stress on your saltwater fish.
