Test kits

[seaweed88]

I have had a 90 gallon mixed reef sitting unattended for a very long time. I went today to do some water checks because it is time to get this back up or in the shed with all the other tanks.
My question is which test kits are being recommended now. I know things have changed since I last paid attention. Thank you for the help. Picking up new kits will be the first step in getting this tank up and running

Red sea and salifert. Hanna for low phosphate

I have Hanna for phosphate and calcium. The rest are Salifert. How long will the Hanna test material last? I know the Salifert kits are over a year old.

Salifert has a sticker on top of box with exp date. The regent has exp on it too. Usually 2 years of use time. Hanna calcium is not so accurate. Salifert is better for that.
