^ I totally agree. Many times people new to the hobby will see better results when they stop adding all that extra garbage. The only thing regular PWC
's will not take care of is Ca
in tanks stocked w/ stoney coral. (Tanks w/ SPS
coral may also have a demand for magnesium additions) Don't forget that beside the salt mix, the food fed to the fish contains trace elements/minerals as well as. Many times tanks have an abundance of them, and PWC
's work to reduce
300? I assume you mean 3 meg/l.? Also your PO4
is very high. It should be .03 meg/l, ideally less. I suspect the chromaplex may have something to do w/ that.
Its the fish that don't last. If its not the temp, what else could it be?
A couple of those things your dosing, ie iodine, are lethal to animals in levels higher than NSW
. That may very well be the cause or at least part of the problem. I suggest discontinuing dosing everything, and just do 10-15% weekly PWC
's. If you continue dosing, you will need to test for levels before making any additions. You may need to do a few large PWC
's a few days apart to get your parameters back in line.
