Well it's all installed and it's great built like the aps bit it's got 2 probably 3 times as much flow as my aps 1400 I'm well impressed with the price tag too just over £50 for it
Orinoco aquatics do them and there exactly the same as the aps... For 1800 lph I'd say it's roughly 900/1000 with the media in but that's awesome for the £50 price tag...
