Hi every one ;
I wanted to share with you my newest project.
I have a 500 l tank with 2 canister filter and 2 small sun sun filter helpers which have each one cylindrical BSB , but since i have 12 adult discus and 4 catfish and my nitrate is hovering around 20 ppm and have no sump i thought to build an above tank sump containing 12 small cubic BSB s .

It basically consist of a 4 inch diameter pvc tube that has been put a series of holes using circular saw cutters ,also put a lid on one end and a screw lid on the other then introduced water coming from on end and leave from the other end back in to the tank. I have used aqualat laterite for the first time and now i have to wait for 8 weeks to see if all this works .
