Skimmer intake had been run outside, I added 15g of Kalk to my 5 gallon ATO. Previously I was running about 25g in there so there shouldn't be any risk of overdosing but I'll watch the numbers.
Any idea how fast GFO becomes saturated when it's sitting in 1ppm phosphate? It's my understanding that phosphate can build up in the rock and sand and then release as it's absorbed by the GFO. So even if the numbers staying stable on the phosphate you don't know for sure if it's still sucking it up or not. Right now there is 15g of RowaPhos that I added just 3 days ago.
