Superfish Aqua Flow 400 Filter 800L/H

Great filter.Bought for my smaller tank to filter water faster and it's great.Was very noisy to begin with but now it's silent.Every so often it will be loud for a few seconds and after water changes it can be loud but it always reverts back to silence.

Really good value, these are a decent quality filter for small tanks. Easy to clean, good size, performs well in the right tank and easy to fit.

works ok but gets noisy if impeller not cleaned weekly!! seems a bit cheaply made but then it's a cheap filer.I use it as a back up. Have now bought an Eheim.

i have purchased this as a backup on my 100ltr tank,tried it out for the first time today,i must say this is quite a powerful filter you can adjust the flow with the valve provided.the cartridge filter tends to pop of away from the power head something you have to look out for when you have cleaned and put back in the tank,the pump is a little noisy at first but having the superfish 200 i found that after a while it will quieten down when the impellor gets a coating of slime sort of self lubricating.these will give you crystal clear water given time time to start working after a couple of days.for the price they are quite good filters.

I bought this and it was a complete waste of money. Don't buy.In theory, sounds like a great little filter. In reality, awful build quality and noisy.The media compartment isn't snug, it falls off of you even look at it funny. Mine cracked within 3 or 4 times of me taking it off. The suction cups are weak and it slides down the glass within minutes. It's also noisy. One of the major positives of an internal filter is that they are quiet but not this one.Just don't buy it.

Awesome filter I couldn't recommend highly enough

The plastic was cracked in 3 places when it arrived. I have managed to repair it for the short term.Also very loud compared to my previous filter

Bought the 300 and 400 and have used the smaller filter in tank. Easy to assemble and has worked well last 2 weeks and has improved clarity in the smaller tank. Upgraded from a 200. Keeping the 400 for Juwel 240 if needed.
