[SOLVED] I want to scale ParticleEffect - Libgdx

Basically my problem is simple - I have a ParticleEffect which looks nice on small screen but on my private phone (Samsung S4) it looks very small. My question is: How can I scale the effect?

I have already done something like this:

// Callback method
	public void addEffect(Vector2 position, boolean special) {
		// Callback Method for the particle effects
		PooledEffect effect;
		if (!special)
			effect = (MathUtils.random(0, 1) == 0) ? yellow_star_pool.obtain()
					: green_star_pool.obtain();
		else
			effect = special_star_pool.obtain();
		effect.setPosition(position.x, position.y);
		effect.scaleEffect(Values.Scalar_Width*1.3f);
		effects.add(effect);
	}

But the result is that the effect is scaling exponentially, something I don’t want.

I just want the effect to be scaled so that it will look the same on all screens. How can I achieve that?

UPDATE: Ok I managed to solve this by simply reset the effect pools at the end of each effect. In that way, the pools doesn’t grow exponentially.
