1. Should i buy a gravel vacuum to suck up all the old food pieces in the bottom of the tank, will that work for this purpose?
2. Do i need to do a complete water change of the water in the aquarium since it doesn't seem like the partial water changes have helped in bringing down the ammonia levels? ( i know not to mess with the bacteria that has built up in the filter itself, only to rinse it in the old tank water if necessary and to use water conditioner when putting in new water) but since the ammonia levels are extremely high, if i do a complete water change of the tank water after i use a gravel vacuum to suck out all the old stuff, will that help or hurt the situation?
The ph, nitrites, and nitrate levels are all fine, it's just the ammonia level is WAY too high. Help! Thanks
