Definately needed the clean, its suprising what gets in there and how quickly it can happen.
Your filter was probably slowly turning into a Nitrate factory with all that yummy bio-gunk in there.
The Phoscleaner will be fine as long as you dont restrict the flow around it too much...if youve got a good output flow it should be fine.
These products are normally placed at the top of your filter cartridges,just before the water enters the impeller well.
When packing your filter,it normally goes (from bottom up) Biological,mechanical,chemical. Of course, some people alter this to suit their particular situation but that's the standard setup.
Throw a filter wool pad in between each layer and your water will be sparkling clean.
Have fun GG : )
