What should i fix first?

I also have guardex 4 in 1 OTO test kit. The sellers left it for me.
BTW are the nicer kits K-2006 or TF100 are only available directly thru manufacturer? I cannot find them on amazon or on discount anywhere. Just checking...

Assuming you are on the East Coast of the US order from the link in my signature. If you are on the West Coast, there is a different distributor, I believe it is PoolSupplyWorld. The Taylor K-2006 should be available on Amazon, though I recommend using one of the two stores I previously mentioned.

I would order from tftestkits.net. The owner, Dave is frequently helping here on the forum.
