Protect your biofilm

Recommended Posts

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.

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.

      Unfortunately unless we can get at the black shrimp and cull everything else constantly we will always end up with a few blues etc. I tried for sometime to get just blacks but I think it must stem back from when the blacks were first being bred here and nearly always kept with chocolates. Even back in my 2013 colony that i got from Dean there were blacks and chocolates together. The blues didn't start turning up straightaway but even with culling I ended up with all 4 colours. i know many people have the same issue when trying to breed the blue diamonds- blue from black -they have to cull hard and constantly and truthfully I don't think any or at least only a few have a large colony of blue diamonds that breed 100% true.  You need to try and find a few blacks that don't show the deep blue - try putting them in a white container near a light source - you will see the blue/black colour more readily -if you are lucky enough to get a trio of true black without the blue base you might get started -good luck!

      That is less than 5%, so that should be safe. But maybe change it over every 3 days. Or every week, if you want to be safer.

      Thank you for the imput Ineke. I too started with a mix of chocolate and black, nearly lost the lot thanks to an invasion of dragonfly caddis's and I ended up putting the few survivors into my 1000L pond. Months later I found chocolates in the pond and got interested in trying to get a good tank of them again. I swear my black cherry shrimp tank is determined to do my head in...….Almost every shrimp in there now is either blue (and practically all the shrimplets are blue) or a very definant blue/black. And the 4ft where I put all the dark chocolates are now producing lots of blacks. I know its an odd thing to complain about, getting too many blues, but come on I really loved the glossy all black cherry's. Oh and on a side note. In the dedicated Blue cherry tank I am getting deep blues, clear blues (diamonds?) and apparently for good measure blue rilli. And there is no way the shrimp can get between the tanks because no swapping around of plants has occurred and the tanks are a good 2-3m apart over a concrete floor.

      What parameter are you keep taiwans tibees?   What tds you get wiht salty shrimp mineral? And what gh? 1 have 3 same tanks 100liters, same setups.
