The high charge current produces a surface color, which corresponds to a state of charge of 70â80%, although the average SOC is just 45%. The high discharge current also forms a large gradient of the state of charge in the graphite anode, which is reflected in a black color. Due to this color we presume that the anode surface has a very low SOC.
The ongoing costs of a pool (electricity, maintenance, and repairs) can cost owners $3,000-$5,000 or more per year. In an effort to save money, many homeowners decide to tackle pool cleaning on their own.Using the monthly pool costs outlined above, that can work out to yearly savings of more than $1,000. Extremely dirty pools (so murky that you canât see the bottom on the deep end) might require a drain and clean service that runs $500 to $600 or more. 2  Pool acid washingârequired for the most stubborn pool stainsâcosts $200 to $300 in addition to the cost of a drain and clean.
Marvin. The pool estimates I have been exposed to would put the installation cost in the $15,000 to $25,000 range for decent pools. Upkeep costs should run in the $125-$150 per month.It costs $75 - $100 monthly for a maintenance company to stop weekly, check the chemicals and keep everything tuned up.nce filled ($500) it was easy to top off with the house water supply. Chemicals ran me about $300 / year and it took a lot of brushing and vacuuming to keep it nice and clean. Here a pool can cost $30k to put in the backyard.
