The power filter, is one of the fundamentals of the DSR method.
It is just a a name for a strong pump with filter wool on the intake.
It removes annoying small particles and clouding from the water, which prevent detritus from settling in low flow area. It’s essential to manage an optimal flow ( not necessary strong), to keep the dirt into suspension, so it can be picked up by the power filter
A optimal working power filter can produce a crystal clear result, without any additional filtering media. A power filter require a powerful pump
Minimum is capacity required:
– 1000l/h for tanks up to 200l ……….. (H.max > 1,25m)
– 2400-3000l/h for tanks up to 1000l (H.max > 2m)

Optimal performance is reach by replacing filterwool every 2-3 days. Use alternating flow and occasionally stir up the sandbed if it takes longer for the filterwool to get saturated. Don’t use the filterwool longer than 5 days, because it will have an ill effect on the corals. A well maintained system can go without a powerfilter for a few weeks. i.e. during vacation

Why is Aquarium carbon (GAC - Granular Activated Carbon) not used in DSR?

Normally, due to the decomposition of organic material, the aquarium water will become cloudy and eventually turn yellow. Normally this was addressed with water changes in combination with activated carbon.

In DSR we do this differently. We do not do water changes but use the combination of:

A- fullDSR, Powerfilter + CarbonVS + Fe + (optionally supported by a skimmer)

B- EZDSR Powerfilter + EZCarbon (optionally supported by a skimmer)

This combination (A / B) filters the water crystal clear.
If you let the PF become completely saturated (let it work for max. 8-12 hours), so that it generates micro bubbles, it will eventually even remove the existing yellowing from the water.
This achieves almost the same clear water effect as with the use of activated carbon.

This effect only takes effect if the power filter is used for a maximum of 5 days and between 2-4 days and only if there is enough dirt to clogged up the filtermedia, so it can filter out micro particles.
If the system does not contain any dirt, it will never come to that.

Activated carbon is only used in emergencies and poisoning. E.g. in case of fish death or overdoses.
