Hello folks!!! Im in the middle of listing out my equipment to get an octopus (fancy a Bimac as my first) and im about to hopefully buy a tank in a couple of weeks from somebody selling one on a reef site. I have read so much on Tonmo.com (quality site!) and many others. However, since im new to this game and am begining to wish I stayed awake in science at school!! Im starting from basics, so just understanding what feeds into what is a challenge, but makes me want it more!!! Now I have a list of equipment thats part of the deal and im aware of other bits I require (which I'll list below) and was just wondering if anyone could shed some light on my ideas and tell me were Im going right and wrong and any other equipment I need to budget for...... Tank (40 UK gallons, drilled with corner weir) Rowa carbon 500ml Elite 802 Air Pump TMC Hydrometer Tronic 200 Eheim 1260 Return Pump Things I know I need on top of the above.... Skimmer (Deltec AP 600 or Turbo Floater 1000) Sump (poss sit skimmer in and section off for sand, live rock and algae) Starters Light/s Would anyone know any equivalent skimmers incase I cant get my hands on one of those two above. Also do I need another pump? Now I know I obviously require my aquascaping ontop of the above, but can anyone think of anything else, Ive prob missed one of the most important things other than me new mate Inky!!! Thanks for your help in advance. All the best Scouse p.s. im aware I may require a chiller as I live on a ground floor flat with the boiler room below (gets warm) but was gunna wait until my tank is setup an I can judge what the water temp is around and if i need one?????
