Brass misting nozzles and copper toxicity

[Mux5870]

Hello all,

I have worked really hard on my viv for a while now, and im close to having it finished and populated with plants and animals. Have worked hard to get light, temp and humidiy requirements right and build hood.

I bought a misting system, the lucky reptile super rain system and have been testing the misting in the tank with RO water. Ive probably misted about 10-15l into the tank so far in the process of testing and setting up. Tank is approx 55 UK gallons.

While researching the plants im gonna keep, bromeliads, I came across the fact that they are very sensitive to copper toxicity. The lucky reptile misting nozzles contain brass parts and hence copper.

I have replaced the brass nozzles with plastic ones now......but i am still concerned about the water that has already been pumped into the vivarium while testing with the brass nozzles?

Now i dont know what to do......

Do i need to replace all the substrate in the tank and start again?
or
Shall I just forge ahead and continue as I have now got rid of the brass nozzles?

Is there any way of measuring the copper content of my substrate?

If the water that I have misted into the tank has evapourated, does that mean the copper that may have been in the misting water is in a solid state now?

Thanks in advance.........

nozzles shouldn't matter. i'd be more concerned with whatever pipes your water is supplied through than brass nozzles... even after r/o.
