Needing help with supplements
 
Just started a marine aqaurine, currently have 2 common clown fish, 3 cleaner shrimp, 5 hermit crabs, 2 varieities of plant and two pieces of coral. 10kg live rock.

I'm struggling with dosing supplements which the LFS recommended but they dont seem to be very helpful after they have sold the product.

Currently I add 5ml of "Reef Success Coralgro" each day when feeding.

I also (this is where i struggle) am trying to add the following:
5ml of "Reef success Calcium+3" per week
5ml of "Reef success Buff" per week

both of which i have been recommended to add to top up water. The only problem is my top up water comes from the tap conditioned with "Prime - Freshwater $ Saltwater"

So basically I need a little help in black and white of how much to add and when and how.

Any help would be grateful.

I do 25% water changes every two weeks using pre-mixed ro salt water from LFS using Red sea coral pro salt as a start before i attempt to mix my own batches.

well, to really know how much you should be supplementing, you should be testing your water also. Just taking it to the store and having them tell you "your water is good" isn't good enough, you need actual numbers. Calcium should be between 400-450 ppm, and your Alkalinity should be between 8-12 dKH. pH should be around 8.3, Magnesium should be around 1250-1350 ppm, or three times your calcium. When you test the water and your levels are low, then you supplement accordingly.

If you test weekly, you will know what your water parameters are, and also how quickly they drop over the course of a week. After not too long, you'll get a good feel for how your tank behaves, and you can dose throughout the week to keep your water stable without over-dosing.

A side note, its very unadvisable to use tap water for a saltwater tank. Tap water contains way too much phosphates and silicates, and will almost certainly result is massive algae problems in the long run. The tap water conditioner removes chlorine and such, to make the water safe for fish, but it doesn't (can't) remove the phosphates and silicates that will feed algae growth. It's best to use RO/DI water (reverse osmosis, de-ionized), either from a unit you buy for your home, or bought from the LFS. RO/DI water is usually very cheap (I used to get 5 gal buckets full from teh LFS for about $2 before I finally bought a unit for my home... I got tired of lugging buckets to/from the LFS lol).

How big is your tank? How long has it been set up? What kind of filtration do you have running? What kind of lights? Give us as much detailed info on your tank that you can.

I agree 100% with Conger on this one. Adding supplements to an aquarium without knowing the existing levels is a recipe for disaster. Every aquarium uses these supplements at a different rate. It is impossible to use any rule of thumb when recommending a dosing routine. You have no choice but to test.
