Question
Hi Leigh, I live in NorthWest Indiana, wanted information on building a watergarden around 4000 gallons. I had one with my old house 1000 gallon with fish and plants. My problem is filtering system. Clogged up and fish died. Plants were OK.
Second problem is new house using well water. Very hard and lot of iron. It is not good for aquarium, fish die, too.
Can fish and plant servive with softwater thru water softener?
What is a good water filter system I should have?
Thank you very much

Answer
Yes they will probably survive on sotened water. I don't think thet is your problem. Look into a biological filter.
There are many websites telling you how to make a biological filter. On your search engine put in biological filter. If you find nothing E- mail me at [email protected]
Iwill try to give you a detailed description with a picture.
