Needs help with fluval filter

[outacontrol]

I tried running a fluval 404 on my salt tank, it worked ok for the first 6 or 8 months. Then I started getting alot of algae growth, I tried different media, no media, more cleaning of the filter and nothing helped. I removed the fluval and things turned around and started to get much better. I installed a couple of Koralias for flow instead.
SO the long and short is ditch the headache, I mean fluval.
