Temeratures control with outputs

Using Arduino Programming Questions
24

I will have different temperatures at the end. Now I have lower temerature so I can test it in the room.

At the and should be like that:

if (tank1temp <= 59)
{
  digitalWrite(tank1, LOW); // pump1 ON
  digitalWrite(tank1RLED, HIGH); // read led OFF
  digitalWrite(tank1GLED, HIGH); // green led OFF
  digitalWrite(tank1BLED, HIGH); // blue led ON
}

if (tank1temp >= 60 && tank1temp <= 62)

{
  digitalWrite(tank1, HIGH);
  digitalWrite(tank1RLED, HIGH);
  digitalWrite(tank1GLED, HIGH);
  digitalWrite(tank1BLED, HIGH);
}

if (tank1temp >= 65)
{
  digitalWrite(tank1, LOW);
  digitalWrite(tank1RLED, HIGH);
  digitalWrite(tank1GLED, HIGH);
  digitalWrite(tank1BLED, HIGH);
}


if (tank2temp <= 35)
{
  digitalWrite(tank1, HIGH);
  digitalWrite(tank2BLED, HIGH);
  digitalWrite(tank2GLED, HIGH);
  digitalWrite(tank2RLED, HIGH);
}

if (tank2temp >= 36 && tank2temp <= 38)

{
  digitalWrite(tank2GLED, HIGH);
  digitalWrite(tank2RLED, HIGH);
  digitalWrite(tank2BLED, HIGH);
}

if (tank2temp >= 40)
{
  digitalWrite(tank1, LOW);
  digitalWrite(tank2, LOW);
  digitalWrite(tank1RLED, HIGH);
  digitalWrite(tank1GLED, HIGH);
  digitalWrite(tank1BLED, HIGH);
  digitalWrite(tank2RLED, HIGH);
  digitalWrite(tank2GLED, HIGH);
  digitalWrite(tank2BLED, HIGH);
}


if (tank3temp >= 70)
{
  digitalWrite(tank3, HIGH);
}
