I guess the difference in soil color is due to the water. Dark brown/black are soaked in water while the dry one are brown in color. Thanks again to bro Bai for sharing this set up process.







hi.. sorry to dig up this thread, just want to check, which air pump is enough to power up these 4 sponge filters? as I am interested to setup something similiar to your setup as well, but not very sure on how is the flowrate of the air pumps calculcated.




I can't advise you on which air pump. As I'm using medo air pump which can support up to 40+ outlet.
For the picture tank it's running a air driven sponge filter and a modify to submerged pump.
For your info now I'm using a sponge filter which come with a pump. Interested to know can pm me your contact, I can show you the picture and location to purchase in whatsapp. As I have not upload picture to photobucket lately.
The sponge filter with pump is Brand: Dophin - Model: SFP16 or SFP34 - Flowrate is 170LPH.
