High Ph
« on: September 20, 2011, 11:12:18 PM »

I have a 450l pond and the Ph is regularly high  Undecided. Don't ask me for precise readings: I can only tell you that my testing solution is closer to dark blue that light blue  Angry. So, my question is: what causes high Ph in the first place, and what measures, other than adding 'Ph Down', should I take?

Appreciate your help.  Smiley

On a second matter, my pond receives a few hours of direct sun  Cool from about 9am-12.30pm and dappled sunlight (trees everywhere here!) until 3pm. Given these conditions, what plants should I have that will thrive and possibly oxygenate the water?

The pH is fine, as long as it won't fluctuate you don't have to worry. Rain will probably soften up the water a little when that comes anyway c: There could be a number of minerals and stuff (lack of better word) that can change the pH.
Goldfish will easily enjoy a pH ranging from 6.5-8.5, so do not fret. As long as it won't change back and forth, they'll be fine Smiley

Many people come to this forum all the time asking "My pH is high, I tried to lower it, now my fish won't swim!" and stuff like that. The answer to that is always: Do not meddle with the pH as long as it's not crashing or rising on it's own. (And then it's most likely because the tank's over crowded or the filtration is inefficient, usually both.)

Hope it helps c:

Nossie' right Bob, I wouldn't worry too much about it... and if you try to adjust it lower it will just increase again in time back to its natural level... adjusting it will more than likely upset the fish as well, they dont like the Ph to change to quickly, it sometimes causes them to flash about... also the PH reading becomes blue at about 7.0, under 7.0 it has a definate green tint to it and it starts getting yellower as it decreases... my ponds sit at about 7.4, which is a dark blue colour... I suspect yours is probably about the same. cheers

Thanks for filling in the blanks, Ron (on the colors of the strips).

If the pH is 7.5 it's basically the ideal for goldfish, and obviously that's a good thing Wink

Thanks for the advice. I was expecting to receive notification of your replies but nothing appeared and I didn't check! My bad.
Ok, I won't worry about the Ph and, since I posted my topic, have done nothing to the water. Today it was not as blue as it has been and I will let nature run its course.
Nice to hear from you again.  Grin
Cheers, and 'GO CATS!!'
