High Phosphate in Tap Water
So, my tank has been up and running almost a week and generally things are going well (ammonia is at 1.5ppm having peaked at 2.0ppm, most likely due to the Aqua Soil Amazonia), nitrites stable at 2.0ppm, nitrates increasing (currently at 7.5ppm). All of that is pretty good and suggests that the filter is starting to cycle.
Then, the less good news, my phosphate test kit was delivered yesterday and the tank (and my tap water) are reading 2.0ppm. I wasn't necessarily expecting 0.0, but I'd hoped for 0.5ppm or less in the tap water. I was hoping to stay ahead of algae from the start, so I'm a little worried that this is on the high side (and obviously water changes won't help). Is this a high enough starting point that I should be thinking about reverse osmosis or distilled water for water changes?
