Hydor Crystal Mini Internal Filter - review
After a bit of research, I decided on one of the internal filters from Hydor. There were a few features that looked good and the main one being the anti-waste dropout system. If there is one thing I hate is the detritus waste spewing into the water as you take our your internal to clean it. Its brutal. The way this filter is designed, you unclip it from the corner bracket an lift the full filer out and nothing comes away. We will see how effective that is when it comes to cleaning it.
I also liked the size of the filter. just over 9cm wide and nearly 20cm tall, it would fin nicely in the corner of the tank.
Taking everything out the box and putting the filter together took about five minutes. From filling the media chamber with charcoal to clipping it onto the bracket was very quick and easy. The instruction manual is nice and simple to follow of you have never fitted an internal before but having installed plenty over the years, it was straight forward.

The option of a venturi air intake is here too but in not a fan of them personally. I did attach the tubing to have a look and it is very effective adding lots of bubbles but its not my thing.
The filter has been running now for 24 hours and my water is crystal clear, moving about very well in all areas of the tank and the surface has cleared up completely. There is a setting on the actual outlet which gives you the option of high and low. I Went with low because its being used in a shrimp tank. i did test the high and it was a notable difference but too much for me.
I wanted a small, reliable filter and this certainly ticks both boxes.
The crystal filter range comes a few sizes.
