Hi All,

I've been reading quite a bit on the forums and other articles as I want to start making my own supplements for my tank. So far this is what I've got up to:

1. Calcium = Alpha-chem slaked lime (Calcium Hydroxide);
OR else (CaCl) - Where can I get this?

2. Alkalinity = Bicarbonate Soda - why is this necessary if ur dosing slaked lime since that is high in PH?

3. Strontium = Where to get?

4. Iodine = Alphachem Iodine

5. Magnesium = Epsom Salts (MgSO4)

Dude i dont mean to be a stick in the mud but long term using simple chemicals for Calcium and alkalinity you will have an ionic imbalance. For magnesium ie epsom salts alone will result in too much sulphates as opposed to other ions and the chemistry will be skewed no matter how much/many water changes are done.

i guess to boost certain parameters to recommended measurments its ok to use ,then to maintain it u can buy somthing like Seachem adv. calcium for Ca and Mg and Strontium(if u find it let me know :p).
Baking soda is fine to use afaik.
Iodine is not a big factor, too much use will cause algae growth.Best to buy a reputable product which will last u a while.

Key words would be `long term`, as problems only surface after using for long periods of time. Alot has been documented mostly on reefcentral.com about imbalances especially concerning using CaCl2 as calcium additive and Bicarb as buffer alone, very difficuilt to rectify other than huge water changes once established.

Robin, we need some direction from you, on how to make sure these imbalances don't happen :)

only add if you have to. Alot of chemicals (eg strontium) are required in trace amounts anyway and probably occur in high enough conc in the salt you buy. As Midasblenny pointed out, by adding too much you going to screw up ionic balance - eg adding MgSO4 will give you desired Mg, but also increase harmful SO4 levels.
Is there anything wrong with your tank that you need additives?

nothing 'wrong' with the tank, but just like everyone else i would like to add supplement to improve growth of corals.... i understand that magnesium, strontium and iodine may not be necessary in frequent amounts but im sure calcium is required quite often... also based on wat ive read on forums basically every1 is dosing something and promote the use of these things as they say their aquarium & corals have improved...

Agreed that those elements are necessary but the most important IMO is kH Buffer to keep the alkalinity stable.

Agreed, if one wants to dose chemicals then one should add them in the most balanced ratios possible, whilst still keeping the "system" affordable. Having said that, it IS possible (IME) to supplement DIY calcium and alkalinity in a fairly balanced ratio - have you read these threads:
