Hey IceMaiden
Here a list of what i have so far:
Tank - You can use one of your existing FW tanks and turn it into a SW as long as you haven't used any copper based medications. Remember the bigger you go the more cushioning you will have.
Heater - 5watts per gallon is the going rate
Powerhead - Anything that can turn your tank over at least 10x an hour is good 15x good 20xgreat (Thanks SH
)
Lights - Depending how far you are planning on going. I'd say 2watts per gallon would keep all the good coraline and stuff on your LR alive and well. 4-5watts will see you growing softies but you will need more for harder corals
This is where most of your money is dumped in
Digital thermometre - Important to get an accurate reading. Use a cheapo one just for backup
Refractometer or hydrometer - Refractometer's cost a few bob more but are meant to be will worth it. I'd reccomend paying the extra £20 on one. You could end up saving yourself £100's in the long run
Master Kit - Don't use dipsticks they are basically useless. Go liquid tests all the way. I'm using a hagen master kit, seems okay to me
Salt - lots of Different brands, i'm told TMC and reefcrystals are two of the best
Water Changes
2 25litre RO Drum
Mixed Powerhead - Nothing fancy just enough to mix in the salt
Mixer heater - again nothing fancy or too powerfull.
2.5 gal bucket - you could just use your 25litre drums....
Weekly water change - LFS RO water or RO Unit
RO unit and tap fittings - If you want to have more confidence in the water your putting into your £200+ setup you want to make sure you pick up a decent RO Unit. You can use the LFS water at about 45p a gallon buth can you really trust them? How long have they been using the membranes which most suplly plenty of people with water in that area...
LiveRock - Your main or only filtration. Get the best and most pourous stuff you can. Going rate is about 14.50 per Kg
Live arog sand - Helps buffer up Ph
Cleaner Crew - Name says it all
Fish Food - Yummy
Misc - bits and pieces like 6soclet extension, light timers and nets and so on....
