SPS tank want to be

[FuEl]

And here is my current doesing schedule for Ultralith

Ultra Bak 10 drops(~0.5ml) / day 5 in moring and 5 in evening

Ultra Min S 10 drops(~0.5ml) / day 5 in moring and 5 in evening

So for 250 ml bottle will last me for more than a year.

That mean around 35 cents / day (This can take care both NO3 and PO4)

Ultra BIO 20 drops(1 ml) / 10 drops twice per Week

Ultar lith .3 l / every 2 weeks

But i believe when live stock increase will need to adjust this schedule accordingly

So 1 months cost for me now is ~ $31.5

Ultra Bak + Ultra Min S -> $10.5

Ultra Bio -> $5

Ultra lith -> $16

compare to use PO4 remover ~ $90 / 2-3 months ~$30 - $45/month

plus methode to lower NO3 (Not sure how to calculate this)

Now My sump quite simple and easy to maintain

- Skimmer

- Ultralith reactor

- Carbon reactor

Glad you are happy using Fauna Marin's Ultralith System. Very natural coloration of SPS. People who get put off by the initial costs probably have not worked out the maths as you diligently have.

Most people got put off might be due to reactor cost(I lucky got 2nd hand). To me in long run this more cost effective and easier to maintain comapre to :

Control of PO4

- FR for PO4 remover.

- PO4 remover

Control of NO3

- Weekly water change for 20% (for big tank this is no joke now I change 10%(~60l) every 2 week)

- Big refugium

- Denitrator (Cost could be high too and rick of lower Ph in sulpher base denitrator)

I try ultralith because 2 reason maintainence cost for long run and ease of maintainence

Drip the effluet from the denitrator onto a few pcs of small rocks or coral chips in a container, helps with the PH/KH issues sulphur denitrator causes.
