Dosing for SPS

[scunfcu]

Let's say I have 5 sps frags ( 1 to 2 inch in size each ) in a 120 gallon tank with only 20 lbs of LR and one 2 inch Crocea clam. Do I still need to do 2 part solution or use calicum reactor to maintain cal, alk..etc?

Since livestock is low and small and volume of water is 120g, there should be enough enough calicum and misc traces for sps, LR and clam to absorb? Was thinking If I move the frags over to 120g, I can just do monthly water change of 20% to replace and maintain cal, alk.

What chemicals must be supplemented

 

[scunfcu]

Would the size and amt of sps in tank also affect the amt of supplements requirement? I would think that a sps frag doesn't require same amt of chemical supplements as sps colony?

 

[Deanos]

Yes, that's why regular testing is recommended.

Guess, I will have to try it and test the water parameter to confirm. Will have to move the sps frags over to bigger tank anyway, when they outgrow my tank.

Growing clams gobble up calcium!

 

[scunfcu]

Yep, I know the clam is cal demanding machine! Thanks Deano for the link on chemical supplements.

I will keep my sps frags and clam in 20g for now. Until I have $ to setup lighting for 120g and filtration.
