Supplement Question

[gouramiguy]

I have a ten-gallon nano reef with a few mushroom polyps in it. I have been using liquid calcium, iodine and strontium/molybdenum supplements in the tank. Is there such a thing as adding too much? I've been following the directions on the bottle but am wondering if these supplements are building up, since I don't have many corals.

Does any one else use these and, if so, at what ratios/intervals.

Thanks!

Those can all be overdosed. This article covers what needs to be dosed:

Calcium and alkalinity are the basics. I wouldn't dose iodine, strontium, or molybdenum, especially without testing.

never dose anything you don't test for in the first place and determine a need to dose. on a 10g setup you can do a gallon a day water change and never dose anything and have a very successful setup.
