Aquarium Advice Addict
Hi all I'm redoing a friends 55 gal at his business and was looking for advice. He wants his old gravel swapped for sand ( I got pool filter sand) and wants his old rock structure removed and a new one done. ( they're disgustingly dirty). He has one JD in there about 5 inch. Will I be putting the fish at risk changing all this and potentially causing a cycle? I'm not close to there so would not be able to do water changes more often than weekly. Is best bet to save old gravel and toss in a nylon and let sit in tank on top of the sand and also add some to canister filter If I can?
