How much and how often do you feed your fish, and with what do you feed them?
I feed them Hikari Tropical Flake food and Hikari Freeze Dried Blood Worms. I just started feeding these 5 days ago. Before that I had been feeding them Tetra's "Pro Crisps". I don't overfeed, but I have recently changed to feeding them 2-3 times a day for 1-2 mins. Before I was feeding them about once or sometimes twice a day for 1-2 minutes.
Have you tested your tap water too?
Should have mentioned that. My tap water is between .25 and .5 ppm, so I don't think that that is the problem.
What kind of kit do you own?
I use a Nutrafin Fresh/Saltwater test kit.
Excessive feeding or overuse of dechlorinators (ie Novaqua).
I only use the spesified amount of declor for the weekly 15% water change.
You live in the middle of farm land. Is there any chance you did a water change and your tap water is now loaded with PO4 due to the spring run off?
We don't get well water so I sure hope they don't have runoff from the fields in my tap water. (Mental note to self: Drink bottled water :lol: )
From what I've read, if you have high light and/or limiting NO3, you should most definitely expect GW.
I have 100 watts over 38 gallons, so medium light and I just started adding Flourish Nitrogen, Flourish Potassium, and Flourish Trace. I really don't have time to deal with algae right now.
Thanks for all the help,
