SPG - What do YOU target?

mathias999us · 11/05/2008, 08:04 AM

I see a lot of people target different salinities in their systems. Randy Holmes-Farley recommends targeting 1.0264 (35ppt) to match natural sea water as closely as possible - advice which I've always followed.

However, I see a lot of people run their systems lower than this. I've tested the water from local reef-specialty shops, and I've seen them run their reef systems as low as 1.021 with excellent results. Also, I've seen a few people running 1.027 and higher.

Question
What SPG do you target in YOUR systems, and why?

mg426 · 11/05/2008, 08:23 AM

1.026 here.

Gregsgsr · 11/05/2008, 08:40 AM

1.025

I run my tank @ 1.025. If your tank is a "fish-only" tank, I think you are safe dropping the salinity a little lower.

35ppt... natural conditions (so I've been told)

AquaReeferMan · 11/05/2008, 10:27 AM

1.026 in all my tanks.

35ppt

cdness · 11/05/2008, 11:47 AM

1.024 - 1.026 depending on evaporation (still waiting for the ATO)

Typically I keep it at 1.025

mathias999us · 11/05/2008, 12:06 PM

Wow, those are some pretty consistent answers.

Pheeshes · 11/05/2008, 01:32 PM

i keep mine at 1.023 which is half way between the two places i get my live stock from. the coral farm here in ohio keeps their system around 1.020 (sometimes even lower) and phishybuisness usually keeps their systems between 1.024-1025

easye123 · 11/05/2008, 01:37 PM

I keep my sps tank at 1.041

mathias999us · 11/05/2008, 01:37 PM

1.041? Whoa!

runningstix · 11/05/2008, 02:15 PM
