10g4Me Posted September 20, 2022 Share Posted September 20, 2022 Background: I'm a first year reef keeper, about 9 months in. It should be noted that I have never tested my calcium before this date but will be testing it weekly now. While purchasing the toadstool yesterday, I took my water to get tested at my local fish store. I only have soft corals and only do water changes (RedSea salt) within the last couple of months. A couple months ago I did dose reef roids and AB+ a couple times as well. Problem: While testing calcium the Hanna checker was getting 600+, while alk was 8.1. I plan on getting it tested again on Wednesday at another local fish store to see if maybe there Hanna checker was messed up. Is this normal? Any advice for a concerned reef owner?
