frontoes Posted November 14, 2014 Share Posted November 14, 2014 Hey guys, Just wanna grab some opinions with regards to wet and dry trickle filters. I'm currently using one to house a 5ft tank. At the moment I have it structured as from the spinning arm down to filter wool, through a thick black sponge and passing around 4kgs of bio balls which remains dry. I'm thinking of replacing a portion of bio balls into matrix or marine pure balls however I'm not sure if it would work best if either the matrix or pure balls being fully submerged or left dry?I heard that both stuff works wonders reducing nitrates which I'm trying to aim at..Cheers Edwin Link to comment Share on other sites More sharing options...

frontoes Posted November 25, 2014 Author Share Posted November 25, 2014 Should i remove the filter wool and sponge and just have it from the spinning arm straight into bio balls to colonise bacteria? Link to comment Share on other sites More sharing options...
Link2Hell Posted November 25, 2014 Share Posted November 25, 2014 you need to pre filter before it goes over the bio balls so they don't clog upso unless there is something like filter wool around the pipe in the weiror you are using a filter sock on the drain pipe you will need to have thefilter mat over the bio balls and if you have a sponge use it submergedbefore the matrix on end like a partition is good so it acts like aHamburg Matten Filterhttps://www.google.com.au/search?q=Hamburg+Matten+Filter&biw=1920&bih=1004&tbm=isch&tbo=u&source=univ&sa=X&ei=SSB0VN6LL4iGywPtqIH4CQ&ved=0CBwQsAQ Link to comment Share on other sites More sharing options...
