Protect your biofilm

Recommended Posts

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.

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.

      Shrimps will do well with just a sponge filter operated with a air pump, that's the very least you should have in the tank if you intend to keep the shrimps, if you don't intend to keep the shrimps, just feed them to your betta.

      I re-read the post, and I see the shrimp have been moved. As Simon, said, it's best to get the tank at least an air sponge filter.

      I think they have separated the shrimp into their own small tank but the betta is still in the big tank if I have read it rightly?  Simon

      Not a good sign. The fish already has a taste for shrimp. If the shrimp aren't too damaged now, wait till the betta gets hungry.   You need a filter, but more so for your betta.

      Sorry to hear that putting your shrimps with the betta didn't go well. My first betta couldn't have shrimps either as he would go after them. My current betta is ok though, he gets very close and watches them but nothing else? It would be best to have a filter if you can get one small enough, and if it is adjustable have it on low flow because it is a small tank, the shrimps are fine in flowing slow water,! Are you planning to keep them in this tank long-term or is this tank temporary until you decide where to go next with them? It is possible that some may die from injuries/stress/shock etc, but hopefully they will be ok. Simon
