I already have strontium and purple up. What other ones do I need? And what is the best test kits out there?
I recently started using tropic Marin test kits. I think they are a great "mid-grade" test kit.
Cheaper than Salifert and Elos. Better than API.
Haven't used the purple up, but I have it.I would stop using the purple up unless you completely understand the relationship between calcium and alkalinity.
IMO 2 part would be a better way to boost calcium in relation.
