New filter...soundless :-)

For the reason this tank is set-up in my bedroom, and the air pump is making lots of noise, I decided to get a soundless internal filter. I had luck to find, probably, one of the most silent filters on the market. UNI-Filter 280 from Polish company AquaEL is a very quiet filter and has also some other qualities; adjustable water flow, adjustable O2 flow, two ways of hanging the filter box...etc. More info.

Because the air pump (box filter) was very loud, I use to switch it off in the night time for 5 hours. And that is something one should not do. Tanks with no/less filtration will very likely experience blue-green algae, which favours still water. CO2 is highly reduced in tanks with strong air flow. Because of that I highly recommend internal filters instead of corner box filters driven by an air pump in planted shrimp tanks. Of course the filter should have adjustable water flow, like this one (UNI-Filter 280).

The shrimps seem to adjust fine to new conditions and several females have white saddles. I am expecting to see the eggs attached to the females pleopods (swimming legs), soon. I wonder, how long are they developing the eggs before dropping them into the pleopods?
