I've had a 30 gallon fish only tank up for about 5 years and I am in the process of making some changes to it. In the past few weeks I've added 25lbs of LR
and I will be adding 25 more pounds in another month or so. I've also been changing my hawaiian puca shell substrate with live sand. Finally, I've been removing the bioballs from my wet/dry and have been gradually adding LR
rubble. My wet/dry is called a Mighty Max and was made by TRUVU. It came with some filter media called DLS material which is a combination of some type of padding with a plastic mesh layer on top. Other than my protein skimmer, my Mighty Max is the only form of filtration on my tank.Over the years I have replaced the old DLS pads with new ones as needed, but I've had a bit of a nitrate problem and I was wondering if these pads are the problem. It's hard to tell, because it could be the bio balls that have been the problem. Can I get away with removing the DLS filter media? From looking at other people's galleries I've noticed that no one seems to have filter pads in their wet/drys or sumps. Is there any type of filter media or anything else that I would have to add to the wet/dry if I removed the DLS media? What do you use in your wet/dry or sump?
