sadly my fish seem to be coming down with ich so i ran to walmart for a heater and aquarium salt. My aquarium stays 78/80 and the heater i got unfortunately keeps the aquarium at 72 I think lol so i'll be taking it back. While I was there I picked up some filters that were on sale. I have a 10 and a 55g and I want to add some extra filters for a couple reasons. Anywho... they had a 2-10 g whisper on sale for like 7 bucks so I got it for the ten and then they had a whisper 10-30g on sale for like 10 buck so I picked it up for the 55g. Is that okay? Did I do ok?? Also I should probably take the heater back I guess since it is not adjustable. Were the filters a good investment or should I take them back as well and get something better? My aquariums already have filters... I just wanted to add some extras
