I'm pricing all my hosing up today whilst at work lol. Here till 9 so may as well. I think I might go for some thicker hoses tho so it looks a bit more beefy in the bay so thinking 76mm so will bed a 90 51-76 reducer Bend then to a 76mm 90 bend then a 76mm straight piece to the filter. Bit pricey to do this tho lol
