So I've been contemplating on making changes in my sump, so I'm looking to get ideas and other peeps that are new to the hobby can also get ideas for new set ups or whatever. Tank is running good, but I'm just looking to get ideas and maybe try something new. Example, currently have middle chamber full of chaeto, I've been thinking about removing some and adding mud or sand. Another example is placement of equipment such as reactors, skimmer, where is the best placement for them, etc.
