High Salinity.

[wa_lanz]

just got a refractometer and found my salinity to be 1.028...

been searching but cant really find more info so would the gurus care to share wat are the effects of high salinity to sps. eg, slow growth rates or lousy coloration etc..

[scarab]

Don't go searching for info lah, just bring down to 1.025. I think high sg stresses the corals. Not much info available on the actual effect, I've also search before. Before I got my refractometer my sg was 1.029. That time got STN problem and reduced polyp extension.

Indeed.....

But i once heard from an expert from zeovit forum, he mentioned that low salinity level is better for sps from fiji.. Maybe fiji water has lower salinity? I dun know, never been there. This may be the reason why most cannot hold fiji sps colors.

Maybe can do a search in RC?

[wa_lanz]

yeah lo.. couldnt find much info.. all stress on other parameters except salinity...

only manage to read from RC that one guy's sps coloration improved after correcting his high salinity level..

hopefully thats the reason and the end to my ugly sps coloration...

Errr........that's where I did the search

Opps!

Maybe gotta post a question there liao...

that's what i heard too. still can't manage to verify it.

Take a ticket fly to fiji and verify lol.

High salinity stresses corals. In SPS, the colours may be affected adversely and weaker specimens may experience STN. They may not encrust as quickly either, i.e. slower growth.

NSW ranges from 1.025 - 1.026 in most places. The Red Sea is a little higher I believe.

I keep mine between 1.024 - 1.025.

Opposite of me....here dropp only 1019-1020

how to increase ? .. dose some seasalt directly or any method please....

[Venezia]

pls do not dose sea salt directly. u may harm the organisms in your tank especially if the salt falls onto them---> salt burn.. then the tissue affected will start to die off

Bro, pre-mix the salt in a pail 1st, den pour into ur tank...

Drop the specific gravity slowly. Like 0.001-0.002 over a day to minimise stress. It would be more accurate to read salinity in parts per thousand (ppt).

Thanks I'll do mix first the salt in apail..
