Average maintenance cost per year?

[Killamanjaro]

I've been trying to work out how much a mixed sps/lps reef would cost in terms of maintenance per year. I understand that it varies from tank to tank, size and stocking. I'm looking at the Fauna Marin balling light method and trying to get a yearly cost.

How much does a tank of around 513litres/135gallons consume in terms of alk, mag, cal? Would a 4kg tub of alk, cal and mag last 6 months or would it be gone in 3 weeks?

Is there an answer to this kind of question, it doesn't need to be accurate... Just an estimate.

If it helps the parameters would be around 35ppt salinity, 8.2dkh, 420mg/l Cal and 1390mg/l Mag. It would be a mixed reef, slightly sps dominant.

My 100 gallon tank costs me about $960.00 a year including electricity, water changes, food etc.

Ok so through various discussions and reading forums I've come to find that on average a good SPS reef of around 513l/135gal will be going through 1-1.5dKH per day, 2dKH if you're doing really well and corals are growing fast and 3dKH if you're a genius.

Now obviously this varies up and down dependant on tank size and corals etc but would you guys say that is about right? how much do you guys dose in terms of ALK and Cal?
