Fish will produce waste, this waste breaks down and chemical called ammonia becomes present.
Ammonia is quite toxic to fishes even in small amounts, fortunately ammonia is consumed by bacteria (mainly in the filter media). The ammonia consuming bacteria produces another chemical as a result, nitrite (which is also toxic to fish). Again, nitrite is consumed by another type of bacteria and as a result nitrate is produced. Nitrate is less toxic to fish than ammonia and nitrite, but routine water changes ensure that it stays at an acceptable level.
When people say they are "cycling" a tank what they mean is that they are waiting for enough bacteria to establish so that ammonia and nitrite are no longer present in the tank. When a tank has reached this point it is referred to as "cycled".
These are two options to cycle your tank:
- Fishless cycle - adding ammonia yourself to simulate the ammonia that would be produced with fish (less time, no risk to live stock)
Fish in cycling - adding a few hardy fish that will be able to withstand the ammonia and nitrite spikes while doing frequent water changes (more work, less choice of fish, but you do have fish right away)
Mature media (media with bacteria already established) will allow you to complete your cycle sooner, which is why I asked.
The "Cycle" you have probably won't help. I don't have any experience with these products but almost all instant cycle products seem to lack support on these forums atleast.
The product you added to remove chlorine was recommended to you because chlorine can affect the bacteria in your filter. Another chemical called chloramine is also added to some tap water and may cause similar issues, although some users do not use any dechlorinator and do not experience any adverse affects.
Finally do you have the packaging for your filter to find the model? I don't know alot about internal filters but it does look quite small for a 150l tank.
Hope that helps, let me know if you have any other questions.
