JoeQ Posted December 27, 2023 Share Posted December 27, 2023 Is it common to have Phosphate in tap water? Link to comment Share on other sites More sharing options...
Pepere Posted December 27, 2023 Share Posted December 27, 2023 I would suspect it varies from region to region. My tap water has very low levels and I do 50% water changes weekly. My water is also very soft both gh and Kh. I add phosphorus, calcium, magnesium, iron and Potassium at every water change in addition to Easy Green as it is rather low in those nutrients. It is very reasonable for Easy Green to be light in those given widely variable source water and water change schedules… I learned about phosphorous by putting in a phosphate reducing pad that came with my canister filter and having my Anubias get suffocated by green spot algae…. Testing phosphorous levels in tap and tank water led to removal of the pads and weekly dosing of phosphorous…. The anubias recovered but many leaves melted. But now they are pristine and thriving… Link to comment Share on other sites More sharing options...

But now they are pristine and thriving… I recently got some seachem liquid tests on account of not exactly being thrilled with API. At the same time I got the seachem Phosphate test when it caught my curiosity. The nitrite/nitrate test seemed accurate (ill have to compare tomorrow). The phosphate test caught me by surprise with 1ppm from tap and 3ppm in tank even tho I cut way back on phosphates!!! Of course I'll retest tomorrow with fresher eyes... Maybe I cross contaminated some how... Regardless, that pushed me down the Phosphate rabbit hole Edited December 27, 2023 by JoeQ Link to comment Share on other sites More sharing options...
