I currently use the Acurel Media Pad for nitrate reducing in my biocube intank media holder. I typically used filter floss up to this point. Any who, I'm just now realizing that Acurel makes individual media pads for ammonia reducing, phosphate reducing and carbon infusing as well. Is it a bad idea to combine all 4 pads (ammonia reducing, phosphate reducing, nitrate reducing and carbon infusing) together and use them within my intank media basket? I guess my thought is, the more the merrier. Lol! Or maybe that's a bad idea. Excuse my ignorance if this sounds completely ridiculous, I started my tank March of this year. I've learned a LOT but I have a lot to learn as well.
