Keep SPS with NSW with vibrant color

[patrick123]

Anyone keeps SPS tank using NSW and still have vibrant color? I was told that NSW around Singapore are highly polluted and are not ideal for keeping sps. Anyone has success doing it using NSW?

Been Using NSW for quite some time. . . No issues . . . U however need to maintain your KH/MG/CA concentration closely . . .

And do not store NSW in air tight environment . . Best to use it on the same day you bought it. . . . or store in a huge pail with a pump or Aerator running. . .

Copperband, Thanks. Any picture to show?

Anyone else?

2nded copperband, been using NSW for my mix reef since Feb last year (life of my new tank). Do water change every wk at 50 lts, with a raise of sg from 1.020 to 1.024 with TM salt preferred (just three cup to maintain KH/MG/CA)

Attached of my FTS taken on Nov last year.

Wow. Nice tank you have there thairun. Any recent photo to show?

[thairun]

Thanks JuzzMarine,

the latest photos taken last week of my 5 footers FTS at left and right. But sps look not really hold a good colour due to high nutrient of NO3 at 5-10ppm believed to be high porosity of live rock accumulated detritus or NSW itself hard to maintain low nutrient? No problem with growth and PE.

Beautiful

I see that you have a bare bottom tank? Did you add additives to compensate NSW? i'm currently cycling my 15 gal nano bare bottom using NSW and planning to keep SPS. Though i know iwarna uses NSW and has nice tank but i want more opinion that it can be done and i'm sold! Thanks Thairun

Apart of my bare bottom main tank, I run a 2.5'X2.5' cube DSB refugium with algae and 100's of mangroves to curb zero phoshpate but sadly not nitrate. Also, I run another a fragging tank 3 footers to make a total of 1000ltrs system.

In every batch of water brought by my LFS, I will check once all parameters so necessary additives will be added accordingly beside to assure the pureness integrity. Mainly I put particular attention to the KH/MG/CA additives. Most of the time it comes at natural state and I raise to 20% more. Ever I raised more than that and resulted in snow storm (marble theory?)

I use kalk reactor for my DI top-off water to compensate my 2XCR (Coral Lab and Korallin) at effluent of ph 6.2- 6.5. Some MG granule added in the Korallin to cope up with heavy intake of my coralline algae and corals. I drip kh builder and strontium when necessary and add coralvit, amino acid and iodine weekly.

I think that will help you forsee the attention needed for NSW in MHO. It always hard to get a good batch of water at zero TDS! Use to be at 10 to 20ppm, fyi.

Am still in a direction in learning wave action and lighting regiment to bring sps colour

Happy reefing!

Sorry, it typo error. I mean bought from lfs for a cost of $2 per jerry can. That mean a week cost me a WC only $6 exclude salt mix to beef up sg.

For your information, the nsw come from off shore Changi near Johore shoal. The following are test generally taken for the water approximately;

Sg - 1.020

Ph - 8.2

Kh - 7

Ca - 350ppm

Mg - 1110 ppm

PO4 - undect (Salifert)

NO3 - Undect (API)

FYI
