Dosing question

[Sexytang]

I have a 36g bowfront that has been setup for 10 months or so. It’s got lots of corals in it. I haven’t got a alk or cal test kit yet will prolly be awhile before I get I’ve due to other things I need more. But the question is would it harm anything if I dosed a little alk and cal to maybe help some of the corals

Tank setup is just weekly 5g wc
Hob filter with carbon with zeolite crystals
Sw4 jebao on else
Black box light

I would not dose anything I can't test for. You don't know what you have! Order up test kits or Hanna's and find out where you stand.

You got a nice tank! I think you will be fine with water changes until you get your test kits in.
I really like the Hannah for Alk . Red Sea for calcium , and salifert for Mag cheers
