Hi all,
i have an Aqua 850 tank (approx 20g) with an external spray bar filter which came as standard when i bought the set up.To this i have added an under gravel filter with 1 lift tube.My question is do i realy nead the UGF and could this be effecting the water cerculation and flow for the external system.It is a community set up with real plants and has been running in this state for about 5 months now.
