Can't put ground on the correct place (circuitikz)

I want to add some decoupling capacitors to my circuit but it's always placed wrong. It should just be at the bottom of the capacitor. What am I doing wrong?

 begin{circuitikz}

    draw

    (0, 0) node[op amp] (opamp) {}

    (opamp.out) -- ++(1,0) coordinate (out)

    (opamp.-) to[short,*-] ++(0,4) coordinate (leftC)

    to[C]           (leftC -| out)

    to[short,-*]    (out)

    to[short,-o] ++ (1,0) node[right] {Control input}

    (leftC)   to[short,*-] ++ (0,1)  coordinate (leftR) 

    to[R]           (leftR -| out)

    to[short,-*]    (leftC -| out)

    (opamp.+) -- ++ (0,-0.5) node[ground] {}

    (opamp.-) to[short,-*] ++ (-0.4,0) coordinate (Rnode)

    (Rnode) to [R,-o] ++(-2,0)

    (Rnode) to [short] ++(0,1) coordinate (sensR) 

    (sensR) to [R,-o] ++(-2,0)

    (opamp.up)  to [short,-o]  ++ (0,2)    node [above] {${+10V}$}

    (opamp.down)to [short,-o]  ++ (0,-2)   node [below] {${-10V}$}

    (opamp.up) ++(0,1.5) coordinate (up)

    (up) to[short, *-] ++(1,0) coordinate (leftCplus)

    to[C] ++(0,-1) (leftCplus |- opamp.out) node (Cplusbottom)

However, to have good unit, you should use siunitx:

documentclass{standalone}

usepackage{circuitikz}

usepackage{siunitx}

begin{document}

 begin{circuitikz}

    draw

    (0, 0) node[op amp] (opamp) {}

    (opamp.out) -- ++(1,0) coordinate (out)

    (opamp.-) to[short,*-] ++(0,4) coordinate (leftC)

    to[C]           (leftC -| out)

    to[short,-*]    (out)

    to[short,-o] ++ (1,0) node[right] {Control input}

    (leftC)   to[short,*-] ++ (0,1)  coordinate (leftR) 

    to[R]           (leftR -| out)

    to[short,-*]    (leftC -| out)

    (opamp.+) -- ++ (0,-0.5) node[ground] {}

    (opamp.-) to[short,-*] ++ (-0.4,0) coordinate (Rnode)

    (Rnode) to [R,-o] ++(-2,0)

    (sensR) to [R,-o] ++(-2,0)

    (opamp.up)  to [short,-o]  ++ (0,2)    node [above] {$SI{10}{volt}$}

    (opamp.down)to [short,-o]  ++ (0,-2)   node [below] {$SI{-10}{volt}$}
