Effective in adjusting pond KH
Easy to use, but unless you know your pond capacity, go o for a lower dose first and retest after sufficient time for mixing. If you have a second pond pump (IE waterfall) switch it on

I have a 5000 gallon open-air pond with a heavy fish load - to reduce costs I collect rainwater in preference to using mains water to replace evaporation and filter-cleaning losses, which means that the pond tends to acidify, particularly during the spring and early summer. I have used Pond Buffer Up for several seasons - it is not cheap (what is these days?) but after a simple chemical test I can easily calculate exactly how much is needed to bring the KH hardness figure back to its optimum. It takes an hour or two watering the pond with a watering-can (so that the treatment is evenly distributed and doesn't disturb the fish before it hits the filtration) but it's an activity that is well worthwhile.
