I think you're wrong Steve. Calculate salt, hydro, water, replacement RO membranes, media, CO2, the list goes on. Certainly more than $30/month.

Oop yeah forgot electricity... maybe $7.50/week? Water is free out here...

yup I was wrong I used 24.69 in power alone.. as for membranes i have that calculated into the cost per gal of water as I use my RO for home consumption so not the whole cost is for the tank. this works out to 0.05/gal and I use 35 gal per week on average so that is 7.00/month, salt is 4.00/month, co2 and media is nothing as I am not running a reactor. so food, about 10.00/month.

so grand total for everything is 45.69/month or 11.42/week so I was under by 4 bucks a week.

and that was estimating everything high.. the most I have ever used is 35 gal of water in a week usually it is about 25 gal. I added 20 percent to my power to compensate for power factor and slight differences in ballasts. my heater never runs but I still put it as 1 hour a day at 500 watts (just in case both were to come on at once.) oh forgot light replacment so add another 5.00 /month so were at 16.42/week.. bah i will juat say 20.00 sence I am going to put a reactor online again.

but out of that I only pay 10 of it :mrgreen:

Steve

as it is here up to a specific amount.. and I have never hit the next stage sence3 I started the tank.. so I pay the same for water weather I have the tank or not.

I think I'm closer to what Brad said, $30/week. Every weekend I'm at the LFS droppping $20-30. I haven't bought live stock for about 4 weeks now. My tank is only 8months old and still hasn't stabilized so maybe if it ever does, the costs will go down.
