I've recently bought a new pump & big new filter box. Water should now be changing more than 1.5 times an hour. No green at all, but water has gone cloudy, although looking clear on exit from both filter boxes. No idea what's wrong as I thought more filtration would be better? Worried that I may be pumping too much water, or it may be simply that the new box hasn't got up to speed yet. Has anyone any thoughts? Fish seem happy enough. I've a 1,000gph & a 800gph pump 25 gallon filter box & a 40 gallon filter box. I've ordered some extra filtration pads in the hope it may help.
Levels all ok, but that's the one, a bit milky. Ive just found a Koi looking a bit raggy, looks a bit unwell although swimming feeding perfectly well. Do you think I should treat pond and fish with an antibacterial additive like Bacterad. Thanks for your advice.
