My five year old 75 gallon chichlid planted tank has a mix of pea gravel and some brand (can't remember) of fairly course black inert sand. My plants thrived for a few years and after long periods of neglect started to die off. I still had a few plants hanging on, and recently restocked with amazon swords, java fern, and anubis. The java and swords are struggling. I recently did a major water change, restocked my canister filter with fresh media, removed all of the algae covered rocks, and a substantial piece of Juniper root (looked cool, but not sure what it did to my water) and added a nice piece of cholla wood. I've also got a corner sponge filter on the way to be used along with the canister. Plan to pressure wash and/or bleach the big rocks. I've also found someone to rehome a couple of really big plecos and other fish that are crowding the tank. I plan to keep a pair of the Kribinsis and rasbora and tetras. The water parameters are all good now and I'm wondering if I should go ahead and change out the substrate, but not sure how to accomplish this with the fish and plants, without removing them. Any pointers appreciated, thanks in advance!
