I work at a shop, so i get these for cheap.
Knop additives
Coral vit j
Coral vit combi
Strontium & Molybendum
Iodene
Mark Weiss
Spectra Vital
Black Powder
preveous to using the spectra vital and the black powder i was using LSB & Reef DNA which seemed to yeald better results.
My rocks seem to be allmost 50 % corraline and 50 % small calcious red fan worms.
I only have a 25 gallon tank so the suppliments last a long time, i am also using a Titan protien skimmer, so i feel that the water is heavily skimmed and therefore these additives are more benificial to me than if i were running a seaclone for example. The only additive i test for is Iodene but i find the test kit very hard to use, and more recently have been trying to dose intuitively as my torch coral seems to react quickly to the addition of this trace element. This is also in conjunction with a calcium reactor and re-mineral m. I am soon to exchange the remineral-m for kalkwasser. Hopefully i should be able to cultivate some branching corraline algie. I have heard allot of reef keepers that only use a calcium reactor and kalkwasser though, but i suppose that greatly depends on the quality of your salt, i use reef crystals, but in future i want to try a two part salt mix as i have heard that the reef crystals can give uequal ammounts in every solution mixed.
You could say that my tank has more dope running through it than an LA hooker on Friday night. But im just playing around with them at the moment. I want to use less in the future when i get the kalkwasser sorted.
