The Aquarium

One of todays newest aquariums within the hobby! The 140 gallon peninsula style aquarium is designed to be the ultimate room divider.
The clever design of the overflow allows you to mount your powerheads and wavemakers on the overflow wall keeping all the equipment discreetly out of view of the main aquascape!

The decades of design pedigree really show in this modern, rimless aquarium kit. With a custom matching stand and purpose-built sump, this aquarium system from Red Sea is going to be my next aquarium! Now I just have to sweet talk my wife!

CaribSea Arag-Alive Sand Substrates
Live sand forms the perfect base for your new aquarium. I have always used and recommended the CaribSea Arag-Alive range of substrates as they are packed with Beneficial Bacteria.

My aquarium uses the Fiji Pink Live Sand but everyone has their own preference.

For this aquarium, 100lbs will cover your base by approx 1.5”.

Rock forms the basis for not only your aquascape but also a place for your Beneficial Bacteria to colonize and form your Bio-Filter.
Creating a habitat for your livestock and a place for your corals to grow on is a fun part of setting up your new aquarium

For this aquarium, a 140lb mix will give you an open swimming space, whereas 200lbs will give you more to play with.

Instant Ocean Sea Salt Mix
To have a saltwater aquarium you need to have salt mix to turn freshwater into saltwater. There are many, many excellent brands of salt on the market but I have been using Instant Ocean & its Reef Crystals brand for many years and I love it.

I like to recommend Instant Ocean because it comes in a range of sizes to suit every aquarium, it mixes well, it’s very consistent and the pricing is reasonable

For this aquarium you will need 1 cup of salt for every 2 gallons, so around 87-89 cups will be perfect for your initial fill, then you will need more for regular water changes.

Remember you have 140 gallons in the aquarium and 35 gallons in the sump.

I usually just get a 160Gal Bucket to the 200Gal box.

I love getting my salt from because of the free shipping – Nowhere else comes close to this!

Monitoring your aquarium water temperature is very important, no matter what size aquarium you have.

This small device can sit discretely behind the aquarium and give you an accurate reading each time you walk past the tank.

This one has no alarms to alert you of High or Low Temperature, but is a great addition to help you keep your tank parameters stable.
