I am a novice/intermediate aquarist. I have a 90gal tank that is 4' long and 2' tall. I had it set up and everything was fine, then I moved across the states. I have changed the substrate from gravel to sand and I put in fake plants. When the tank was set up previously, I had a bio wheel filter for it. Now, I have an Aquatop canister filter that has carbon and ceramic rings for the media. I filled the tank and let it run for a week with no issues. Yesterday, I added some aquarium salt and as soon as I did this, I noticed what look like spider webs coming from the fake plants. I can remove some of them with the fish net, but it all just comes back. The tank is fishless. Does anyone know what this webbing is and how to get rid of it? Will it affect fish when I do put fish in there??? The only light in the tank is the LED bubble wands and natural light from the window behind the tank.
Thanks for your help!!
