HOW THE AQUARIUM WORKS
The eaReefPro consists of two aquariums (*three with eaReefPro180) – the main display
tank on top of the cabinet, and the sump tank below, inside the cabinet (with separate
top-up tank in eaReefPro1800). The object of the sump tank is to hide away bulky, noisy
or unsightly aquarium equipment like pumps, heaters, protein skimmers, automatic top-up
devices, filters and reactors. A sump can also add extra volume to the main display tank
above it. The larger the water volume, the more fish you can keep, and the more stable it
becomes in terms of pollution and temperature fluctuations. Bigger water volume is always
better when it comes to accurately replicating a slice of natural coral reef.
Sump tanks are popular with reefkeepers because they increase volume and house
equipment. With equipment out of sight the main display tank can be aquascaped more
effectively, while at the same time enjoying the best possible water purification (of your
choice,) in the sump tank beneath.
CONNECTED TOGETHER
The two tanks are connected by pipework, to take system water to and from the main
display tank.
PLEASE NOTE:
On eaReefPro1800 models the top-up reservoir is not
connected up by pipework supplied.
Water is pumped into the main display tank from the
sump via the narrow inlet pipe situated inside the weir. Water leaves the main tank first by
overflowing through the acrylic weir comb and then via two wide bore exit pipes situated
inside the weir. Note in normal operation the short exit pipe fitted with strainer should
remove 99.9% of the water from the main aquarium. The tall exit pipe, situated in the
middle of the weir, is there as an emergency overflow pipe and should take very little water
flow when in normal operation. Once back in the sump beneath, water from the main tank
can be filtered, heated and returned using the user’s choice of equipment (not supplied).
Water is circulated constantly when eaReefPro is in operation, and water height in the main
tank will be set at a permanent height regardless of evaporation. The advantage of this is
that even though evaporation will inevitably occur, no coral will ever be left high and dry
due to evaporation influence on the main display tank.
Instead water evaporates and can be topped up discretely in the sump underneath. Another
major advantage with a sump tank is that water changes, dosing and water testing can be
carried out there too, so the livestock in the main display tank above remain undisturbed.
NOTE:
To avoid your sump pumps running dry, and in order for salinity to be stable,
marine sumps must be regularly topped-up with reverse osmosis or deionised water to
compensate for freshwater lost through evaporation. Every eaReefPro aquarium comes
complete with a built in reservoir chamber for RO/DI water in the sump. Evolution Aqua
recommend that all eaReefPro sumps are fitted with a reputable brand of Auto Top Up
device, not supplied.
