Well according to test strips these are the results: Nitrate 0
Nitrite 0
Ttl Hardness 150ppm Ttl Alkalinity Moderate/80ppm Ph 8.0.
The date
stamped on botton is 03/2006 A lot of algae is in the filter
itself...............Thanks

The Ph seems to be really high for a freshwater pond. I keep mine
at 7.4 or below.

My pond, now 13 months old, has always given 8 to 8.5 for Ph. I've
had no problems.
I have some string algae, and the pond planting is going wild! Algae
is a fact of life, I wouldn't worry about it.

Is that the Ph of London municipal water? Sounds like seawater to me.
What's your salinity?

LOL No idea

No offense intended about the drinking water in London. You can get a
hydrometer pretty cheaply at a pet supply shop and find out. Make sure
you get one with as wide a range as possible. Or better yet, just ask
your water authority what it is supposed to be.

I've used pH rolls for decades, for various things. One source is

Thanks, Nick. That will work great for determining the salinity! (note
sarcasm) lol
