Has anyone used these?
Are they resonably accurate?
thanks
I use them everyday, comparable to other test kits I have no idea since I only use the hagen ones, they are reasonably accurate to my knowledge..as accurate as any of the other similar styled ones
I use Aquarium Pharmaceuticals Master Test Kit
- includes GH, KH, Nitrites, High PH, Low PH. Works well.
I know that Art Williamson had problems with Red Sea Nitrate/Nitrite test kits.
Wherever possible I use Aquarium Pharm test kits - and even have one for chlorine. I also use an A.P Nitrate kit - essential if you are cycling your tanks.
Though I have an almost complete set of hagen kits, i usually only use the ones that are not avail from A.P., Calcium, Phosphates, and Iron in particular, though I havent had problems with Hagen.
In fact, offer a good price, and you can pick up my Hagen kits i dont use.
