Question 1

How to place the porous stones in the JBL Cristalprofi e1502 filter for optimal filtration?

Accepted Answer

For effective filtration with the JBL Cristalprofi e1502 filter, it is recommended to place the porous stones in the lower compartments of the filter.

Why place the porous stones at the bottom?

Optimization of biological filtration: The porous stones provide a large surface area for the development of beneficial bacteria that break down organic waste.
Water flow: By placing these stones at the bottom, the water first passes through this biological medium before rising to the other compartments, which improves the quality of the filtration.
Protection of porous stones: Other filter media, such as foams or mechanical filter media, should be placed above to catch larger debris and prevent the porous stones from clogging quickly.

Additional tips

Be careful not to compact the porous stones too much to allow good water circulation.
Regularly clean the filter media to maintain their effectiveness without completely removing beneficial bacteria.

Question 2

What is the correct order of foams and filter media in the JBL Cristalprofi e1502 filter for optimal filtration?

Accepted Answer

Yes, the order of foams and filter media in the JBL Cristalprofi e1502 filter is important to ensure effective filtration and prolong the lifespan of the filter materials.

Recommended order of filter compartments:

Coarse foam: Placed first, it retains large particles and debris, thus protecting the other filter media from rapid clogging.
Fine foam: Placed after the coarse foam, it captures finer particles that escaped the first stage.
Biological media: These materials, such as ceramic balls or plastic noodles, are placed next. They provide a surface for the development of beneficial bacteria that break down organic waste.
Chemical media: If you are using chemical filter media (for example, activated carbon), they should be placed last. They help remove impurities and unwanted substances after mechanical and biological filtration.

Following this order ensures optimal filtration, improves water quality, and extends the lifespan of the filter materials in your JBL Cristalprofi e1502.

Question 3

What is the filtration order of the JBL Cristalprofi e1902 aquarium filter?

Accepted Answer

The JBL Cristalprofi e1902 external filter uses a 5-stage filtration system, with specific materials stacked in a precise order for optimal efficiency:

F1 - Pre-filtration (T-profile foam, 15 ppi): The first mechanical barrier that retains the majority of coarse dirt and debris. This material should be replaced every two months and can be cleaned once or twice before replacement.
F2 - Main biological filtration (JBL MicroMec balls): Highly porous sintered glass material promoting massive colonization of cleaning bacteria. Their different diameters create a self-cleaning action that significantly spaces out cleaning operations.
F3 - Biological filtration (25 ppi foam block): JBL UniBloc medium-pore foam block providing an excellent colonization surface for beneficial bacteria and contributing to the effective biological degradation of pollutants.
F4 - Fine mechanical/biological filtration (35 ppi foam block): Located at the bottom, this fine foam block retains fine particles that could damage the pump while ensuring additional biological filtration. To be cleaned approximately every four months and replaced after three to four washes.
F5 - Optional filtration (JBL SymecPad cotton square): This optional accessory can replace block F4 for even finer filtration, although this reduces the filter's efficiency and requires more frequent changes.

Important: when cleaning, always reinstall the filter materials in the original order. The filter baskets should be rinsed with lukewarm water, and the Combi filter basket must always remain in the last position on top of the filter. JBL MicroMec balls and other biological materials should never be placed in fine mesh nets to preserve their effectiveness.

Question 4

What should I do if my JBL Cristalprofi e902 filter is no longer working or not cleaning the aquarium?

Accepted Answer

If your JBL Cristalprofi e902 filter is not functioning properly or not cleaning the aquarium water, several causes may be behind the problem. Here are the steps to diagnose and resolve this issue:

1. Check the power supply

Make sure the filter is properly plugged in and that the outlet is working.
Check that the filter switch is in the ON position.

2. Check the hoses and water flow

Examine the inlet and outlet hoses for any kinks, blockages, or obstructions.
Clean or replace the hoses if necessary.

3. Clean the filter media

The filter media may be clogged, which reduces the filter's efficiency.
Rinse them gently with aquarium water to preserve beneficial bacteria.
Replace them if they are too worn or damaged.

4. Check the pump

The pump may be blocked by debris or damaged.
Disassemble the pump according to the manufacturer's instructions to check the condition of the impeller and clean any deposits.
If the pump is defective, it will need to be repaired or replaced.

By following these steps, you should be able to identify the cause of the malfunction of your JBL Cristalprofi e902 filter and restore its proper functioning to ensure clean and healthy water in your aquarium.

Question 5

How to effectively clean the JBL Cristalprofi e1902 aquarium filter?

Accepted Answer

To effectively clean your JBL Cristalprofi e1902 aquarium filter, follow these simple steps:

1. Unplug the filter

Before any handling, disconnect the filter from the power outlet to ensure your safety.

2. Remove the filter from the aquarium

Carefully remove the filter from the aquarium, making sure not to spill any water. Prepare a container to catch any water that may spill out.

3. Clean the filter media

Open the filter to access the filter media (sponges, ceramics, etc.).
Rinse these materials with aquarium water or lukewarm non-chlorinated water. Avoid using chemicals or soap that could destroy beneficial bacteria.

4. Clean the filter body

Use a soft cloth or a non-abrasive sponge to clean the inside and outside of the filter housing. Do not use harsh detergents.

5. Reassemble and reinstall the filter

Once all components are clean and dry, replace the filter media, close the filter, and reposition it in the aquarium.

6. Restart and check

Plug the filter back in and check that it is working properly without leaks.

It is recommended to regularly clean your filter to maintain optimal water quality in your aquarium and ensure the health of your fish.
