Tropic marine is good.

nonono...dun use epsom salt. it will offset the sulphate and chloride balance in ur tank.

contains alot of sulphate and will have bad effect if u dose heavily.

still recommend u to use commercial brands which are safer.

u can use epsom salt provided either u have regular water change to clean out ur sulphate

or u also dose baking soda and calcium carbonate to manage the balance.

it's not a recommendation to try.

Can use epsom salt if you mix with magnesium chloride with ratio of 10:1 (mgcl : mgso4) into DI or distill water. Save lots of $$$.

I'm using this mix for a year now in my sps tank any without problem. Maintaining about 1450ppm everytime.

Mangesium chloride - $16 for 22kg (which can last may be more than 10 years) and so far use 2 epsom boxes for a year.

Magnesium chloride from chemical manufacturer in Tanjung Penjuru. Epsom salt from guardian pharmacy.

You can find the info from Reefkeeping , etc,, however, 10:1 ratio should be ok. Or you can refer to the link previously I posted for the steps. I dose about 25ml every 3 days to maintain my magnesium for my 650liters tank.

All the info we need for dosing calcium and mag.

There are many chemical manufacturers around. Important thing is to find out the purity of the magnesium chloride.

I bought a 25kg sack from:

International Scientific Pte Ltd

33 Tanjong Penjuru

S(609029)

Tel: 62611744

Email : sales@ispl.com.sg

Their Mgcl properties :

Descriptions

They sell in sack form. You need your own transport to carry. Also, the magnesium chloride will melt upon contact with air as it absorbs moisture. So what I did is to put into ziplock for every 2kg. 2kg can last at least 6 months for my 650L tank.

[Victor007]

great. really thank you so much for the information.

wonder if u did manage to get ur hands on some calcium chloride too ?

u have enough to sell some to me ? hahaha.

any bro willing to share the cost in getting a 25kg sack together ?

Cheers.

I don't use calcium chloride as I have calcium reactor. There are reefers here know where to get the food grade ones and cheap.

Yeah, I can share with you as its dirt cheap and I'm left with another 2kg only. $10 for at least 10kg, looks good. May be others would like to bulk purchase as well.

[Ah-lim]

yo victor, I dun mind sharing cost,

but its around west area, i see the place...stress....

[Victor007]

great. so we have three ppl here altogether. think should get 50kg in total.then share among three of us.

haha.so around 15kg per person. now who's going to drive there ?

rocky u know the place, maybe u drive there to buy, then we both go to ur place to pack into 2kg packs ?

then there will be 25packs. each of us take 8 pack and the one who drive there takes 9 pack.

everyone pay $10 for 16kg ? i dun mind paying $2more for the petrol fee.

pm me. cheers. we can discuss this together.
