Ok Here I am and I know I am about to open a can of worms so to speak. I have 20g long tank and I need a filter ryanr has been really helpful and has calculated that I need a 32g/hour filter. Now I have looked at filters and pumps and totally bamboozled myself. I like bubbles, quiet and I have a limited budget. This will be a communal tank, possibly live bearers. I know it is largely personal preference, and everyone has their own opinion on the options. I also had a snoop around some specialist stores and find the info on the boxes a bit vague, and as we all know store staff have little or no product knowledge. I am really interested in YOUR experiences, and preferences. I would like to know what you use, why you prefer it and what you see as the pitfalls. This isn't to incite argument but to glean as much information to make an informed choice. Also I suppose availability on the UK market would be useful. Thank You for all the help you have given me so far. Things have really moved on since I last had a tank.
