Got some time working on my 'Shrimp Hills' Project
The Materials
Hardscape: Cut Rawda stone bars, Irregular-shaped Rawda stones, Natural Pea sized Construction gravel (Not Crushed), All for free taken from the Samples Library in our office heheh
Softscape: Christmas moss tied in a thin slate (Got the slates in the office as well)
Fishtank: Found it lying outside the compound gate. Somebody has thrown it heheh (maybe he got fed up with his goldfish bullying his cats)
The good thing is....
No Leaks!!!! (Im a lucky mot#erF@&K**)
Budget: ZERO!!!

Here's the Final look

Added the DIY CO2 with a chopstick diffuser for the moss to kickstart...
