Description: The pond is 1200 gallons, 3 years old, 60-70% cover.
Plants are yellowing and slow growing
No string algie but moderate flowing algie.
Water is clear to 2'
10 7-9" goldfish
20 2-3" goldfish
No bio-filter
37 gallon per min pump over waterfalls
Testing:
PH = 8-9
Nitrate = no colour change on test
Nitrite = no colour change on test
I think I have a nitrate deficiant condition.
Do I bring the PH down first or elevate the nitrate
Is there something else I should be testing for before doing anything?
What would you recommend?
