I've always struggled with the Red Sea Phosphate kit, but I'm also having big discrepancies with Hanna readings on Nitrates
Red Sea phosphate has been telling me I'm around .12 - having been around .03-.08 for months and months before that. Okay fine.
Hanna says my phosphates are .28 across two tests.
Red Sea nitrates says I'm somewhere between 20 and 50 - let's say 35
Hanna says I'm at 14.1
Who do I trust?
Red sea seems all over the place on other kits too - their standard alkalinity and alkalinity pro kits read differently as well.
(for what it's worth I'm doing ~23% water changes daily until I can bring these levels down.)
