Pond Solutions killed all 4 of our Koi Fish. I wish I could give them a rating of negative 5.Regretfully, we hired Pond Solutions to do routine maintenance on our small Koi pond that we "inherited" from the previous owners of our house. We paid monthly. They were supposed to come weekly and as needed, to test the water, clean the pond, and check the overall health of the environment. I estimate that they actually showed up to do what we were paying them for about 10% of the time. Sometimes well over a month would pass and they wouldn't show up until we frantically called them because the fish were dying.Most recently, they had not serviced the pond in well over a month (although they always billed us for weekly service and we always paid). The air pump (that they had installed) continuously lost power and we started calling them....placed at least 100 calls over a 3 week time span and always got voicemail. They only responded once....2 weeks ago, when the owner said he'd be out "in a day or 2." He never showed up.Finally, a few days ago, ALL FOUR of our beautiful Koi fish DIED!!!!! The pond is filthy and it brings me to tears, thinking about what a horrible, slow death they endured because of "Pond Solutions" neglect.After the fish died, we looked at the filter...it looked like it had not been cleaned in months. There is so much scum and the water is filthy....when they were supposed to provide WEEKLY maintenance.
