1) Deciding on beautiful white sand for the substrate then realisng 2 weeks later just how bad it shows up any dirt/detritus. 
2) Realise you want a planted tank and that the planting substrate you prob should have bought should really should be below the 60lbs of white sand so its to late now
3) Order £5 bundle of random plants off ebay plant them where you think then 3 days later notice there all half dead because you didnt feed them any ferts (Now that tank has cycled got nice collection on way from Greenmachine Tropica + and Easy Carbo)
3b) Read planted tank section and realise your shiny £20 air pump hose non return valves & bubble bar will only help kill your plants if you keep em in your tank
4) Do a water change and forget to add the dechlorinator till the end
5) Realise the depth of your precious white sand isn't deep enough for plants order 50lb bag of nice pale brown sand and put about 40lb of it ontop of the white sand.
6) Do a water change and forget to add the dechlorinator till its full (again).
7) When internal filter (bought to coexist with the Fluval 305 external) arrives connect it up at 2am (no I don't know why i waited till then either
) And go to bed forgetting to switch on the external filter. Wake up at 7am in panic and turn it back on (Wasn't disconnected so *should* be ok)
8) Notice your Annubis (sp) ? is looking poorly because your water is so warm to make nice bacs.
On the plus side can't be much more for me to screw up till fish arrive

nearly all the weeds I believe can adapt really really well though so there isn't much worry there!
How about happily gravel vaccing and feeling proud of myself in sucking up great piles of poo only to get that soggy socks feeling 
You guessed it, the pipe had slipped out of the container some time earlier and about 5-6 gallons into the Axminster
