Protect your biofilm

[fishmosy]

There are some times when you need to drop the water levels in your tank, for example, to change substrate. 

You've spent potentially months or even years cultivating a nice layer of biofilm on the walls of your tank. So how do you stop the biofilm from drying out and dying off? 

The simple solution is gladwrap/cling film/clingwrap. Simply lay a piece over each wall of your tank to keep in the moisture.

And when you refill the tank it will float to the surface for easy removal.

Very good to know!

Good tip.

I wonder how much the new (cold) water will effect the biofilm, but it's less then to dry out for sure.

I havent noticed any ill effects, though I dont tend to add water that is very cold.
