Fishtank Systems


This system consists of gravel filter plates and 3 horizontal tubes used for flushing, draining and water circulation. Refer to diagram below. This system is easily assembled by snapping individual parts together with your fingers (No tools are necessary).

Comes with the following:

A: Water flushing tube. Connect to tap water using a garden hose or water tube (5/8”).

B: Water draining tube. Connect to a siphon tube (5/8”) with a hand pump available at pet shops to drain the tank water to sink.

C: Water circulation tube. Connect to an outside filter.

D: Gravel filter plates with a large open space.


  • A water hose (5/8”) to connect Tube A to a tap water fauce
  • siphon tube (5/8”) with a hand pump connected to Tube B
  • chloride neutralizer
  • outside filter
  • water heater

II.  System Assembly

Step 1: Filter Assembly

  1. Place all parts on a flat surface (up-side down) as shown in Fig. 2.
  2. Place a side end seal “D” on the outer edge of filter plate “F”, and a side end seal “E” on the outer edge of filter plate “G”, respectively.
  3. Connect filter plate “F” and “G” by a connection plate “I”
  4. Place 2 identical H-shape parts “H” over the top and bottom of part “I” to secure the connection of two filter plates “F” and “G”.
  5. Flip over the assembled plate.
  6. Insert the water-flushing nozzle “J” into the 3 holes of the filter plate from beneath as shown in Fig. 3.

Step 2: Tube Assembly

  1. Place the assembled filter on the tank bottom.
  2. Insert clear tubes A, B and C into water flushing nozzle J as shown in Fig. 3.
  3. Connect L-shape tube connector K to upper part of Tubes A and C.
  4. Connect Tube C to an outside hung-on/canister filter.

Step 3: Now the tank is ready to use.

  1. Make sure all connections are secured.
  2. Place rocks or wood on the filter plate and then desired amount of gravel.
  3. Connect one side of a water hose to a tap water faucet, and other side to Tube A.
  4. Add water until 1/3 level of the tank.
  5. Add live plants and other ornaments.
  6. Fill the tank with tap water.
  7. Add an adequate amount of chloride neutralizer (not included).
  8. Circulate water using an outside filter (not included).
  9. Hang a water heater (not included).
  10. Adjust the water temperature (24-29°C depending on types of fish and plants).
  11. Add more gravel, decorations or plants to complete decoration.
  12. Maintenance

III.  Water Change and Cleaning (Routine maintenance)

It is important to change 20-30% of water once every one or two weeks depending upon the number and size of fish, regardless of the type of outside filter used. Rinse out the debris accumulated under gravel filter by flushing tap water along the tank bottom, siphon out the debris from other side of tank, and then fill the tank with fresh water.

We recommend to frequently remove leftover foods and fecal matter precipitated on gravel layer by an ordinary siphon cleaner (not included).

  1. Connect Water Flushing Tube A to a water tubing (5/8”) connected to tap water.
  2. Connect Water Draining Tube B to a siphon tube (5/8”) with a hand pump available at pet shops, in which the other side is placed in a large bucket or sink.
  3. Turn off the outside filter.
  4. Siphon out water through Tube B using the siphon tube, and turn on tap water to flush tap water through Tube A along the tank bottom.
  5. Rotate Tube A 90°degrees to wash the entire tank bottom and to flush the debris toward Tube B.
  6. Continue to flush water until debris is washed out completely from the tank (debris washed out from a tank can be seen at the bottom of bucket collected tank water or sink).
  7. Disconnect the siphon by simply removing the tube.
  8. Fill the tank with tap water, and add chloride-neutralizer.

IV.  Total Cleaning of Whole Tank

It is necessary to clean the whole tank once or twice a year. However, it is not necessary to remove gravel again. Just transfer fish and leave all ornaments and live plants in the tank.

  1. Siphon-out water completely through Water Draining Tube B.
  2. Wash the gravel by flushing tap water over the gravel layer, and siphon-out water again.
  3. Repeat several times until drained water becomes clean.
  4. Fill the tank with tap water and add water-conditioner.
  5. Turn on all appliances (heater, hung-on filter, light, etc).

V.  Aquarium Plants

  1. It is recommended to the select right types of plants depending on the tank size, water temperature, pH and lightning conditions.
  2. The water temperature is kept around 71-81°F (23-26°C) for majority of tropical fish and aquatic plants, whereas higher water temperature, 79-86°F (27-30°C), is recommended for discus fish.
  3. For discus fish tank, only select plants which tolerate a high temperature such as:
  • Echinodorus
  • Valliseria
  • Anubias
