reefing is an expensive hobby! from getting the tank, all the equipment and the livestock! But the main expense is water changes and salt! especially if you have a big tank! Everything always must come at a cost! So, how much do water changes cost you each month? water bill, salt and other!
for me, probably around 0.02$ for water and under 20$ for salt!
