!! No Substrate System !!

After I watched a Taiwan Entertaining Show, which showed how a lady in Taiwan took care her crystal red shrimps(and she got lots of king kongs), I found that maybe a tank with no substrate would be easier to manage. Here, I try it out.

This tank is simply equipped, with two biological filters: one regular Oxygen Plus Bio-Filter, the other one is DIY plus. The DIY one is easy to made:
1. place the regular Oxygen Plus Bio-Filter in a quart container;
2. fill the rest space in the quart with ADA soil;
It works better to lower the pH level.


We clean the bottom every two days for most of time. When necessary, we may do more. Suck out waste and the left-over food. No problem with sludge and mug. And no problem with planaria or round worm, since there's no place to hide.

They are doing pretty well so far!

The bottom is like a mirror, pretty but not easy for crs to walk around now. But it will get better after moss grows over the bottom.

Hm, time to clean it now!
