Hello I havn't posted in a while so here it goes. My sister got a betta for christmas and a 1 gal. aquarium, I felt sorry for it so since I got a 10 gal. I decided to put it in there. My parents bought a house and when we move I decided to empty a small garden pond that was in our flower bed (Hard liner) I found the 4 gold fish I bought 2 yrs ago in there and a minnow I had put in there still alive. So sadly for the moment the goldfish (minnow died) are in the 10 gal. till I can get them a permanint water garden. I know it is to small of a place for goldfish but they will be gone when I get money to make a water garden, and I am short on money. Well the Betta is in the 1 gal. and the water is getting cloudy and I need to find a way to filter the water could any body help me on the cloudy water and filter situation? Would plants work on helping keep it clean? Thank you for your time.
