Question about hardness test

[CarlD]

My older son has gotten in keeping fish over the last year. He kept his first fish, a betta named "Ridely" alive for 6 months, changing the water religiously. So now he has a 20 gallon aquarium with mollys and plattys--and the latter keep having babies--and guess who gets stuck testing the water--the guy who knows how to test pools! I was gonna name the fish "Maki", "Nigiri", "Sashimi" and "Sushi" but he really did NOT appreciate that. But with "Mercury" getting pregnant alot, 4 fish is now 8 fish....

Careful, that's how I went from one 10 gallon tank to 2 10 gallons and a 40 gallon tank inside, and an 1100 gallon koi pond in the back yard! If you need something to do with all the mollys, get a cichlid, he'll take care of the problem for you.......
