Nice! mine are in a FOWLR and reef salt levels. i use reef crystal in mine. not real sure how large they are i would guess 8" or so ill post a pic or two soon.
You could make your own salt mix. Save money and adjust the mix to get the PH, and other results you want. You could probably leave out the trace minerals. Here is a link to a recipe. http://www.monsterfishkeepers.com/fo...d.php?t=290665
thanks for the recipe... they are in full marine salt now... i wish i could add other fish but they are way too big now.. and would eat anything i added... will update with pics today...since i am so snowed in here..
