4dkh Solution Warning on eBay
Just thought I'd give you all a heads up if you're planning on buying 4dkh solution from "user name removed" on eBay. I used his/her solution in my drop checker for the past few days with 3 drops of API's PH test solution. The mixture only turned a slight blue-ish green color in my aquarium and I noticed that some of my fish were going up for air (I'm using a DIY setup with about 50 bpm diffused using a siphon head and bio balls) I bought API's KH test kit today to test the 4dkh solution. It took 5 drops to change from blue to yellow, making the solution 5dKH. I contacted the seller about this error, I'll update with what s/he replies with.
With all the testing equipment out I went ahead and made 2 cups of my own 4dKH solution, took about 20 minutes.
