Ok this rookie is seeking alittle guidence from the almighty gurus of this wonderful forum. I have a 125 tank, two aquatech 60 pump/filters, a pro clear 125 wet/dry. I am considering adding one more aquatech 60 and a magnum 350 for mechanical filtration. Question is will what I have now work for two 20 inch plecos, 16 inch pacu, two 8 inch oscars. I have always raised koi in tanks and have always went over and beyond with filtration with these fish due to there waste production. So its been a long time since Ive tried warm water fish but after spending some time on this website I cant help myself but to give it a go. thanks Caleb
