I am in need of a new salt close to NSW parameters as AF isn't working for me. The LFS's don't appear to have the variety like they used to.

Close NSW is MOST reef salts on the market IME.

You weren't using that ridiculous probiotic salt product, were you?

Not really. Even the ones that advertise as such are still typically 440/8.5/1400 or around there at 1.026. I want something like 420/7.5/1300 which is basically Tropic Marin Pro, maybe Red Sea blue (alk is higher) and maybe Brightwell? I haven't been able to try any so I don't know for sure. Fauna Marin is close too but also slightly higher alk. Aquaforest is also higher parameters than NSW IME.

At the end of the day it probably doesn't matter and doing a 10% water change isn't really changing tank parameters that much, but it would still be nice to have the option of something different.

Lol no I wasn't, just the Reef Salt. That being said I have had nothing but diatom / cyano blooms since changing. I will most likely go back to Reef Crystals.

I do a 20% WC biweekly, should I be concerned that the parameters will spike in to GE higher range through the salt?

Really depends on where you maintain your Alk and what the Alk is on the salt your mixing.

I can't even get Reef Crystals here in Regina. My choices are Instant Ocean or Fluval Sea salt and their both quite expensive here. Its a little cheaper and more convenient to order online and pay the extra shipping.

I've found that there is soooo much wiggle room in parameters that being 100% dead on NSW is irrelevant.
