I'm trying to give you my experiences through the past 15-plus years reefing you won't tell me the size of tank you won't tell me what filter you have your parts protein skimmer from what you have said isn't working properly if you doubt my words go ask your Coral dealer why you asking here he should be the one to help you out I don't I research I know what I'm going to buy before I get it and it's going to be comply about with all other corals and invertebrates in the tank that come from the same place using the same watered they're used to by the salinity I keep my pH at 8.4 you can buy this you can put the whole container in the tank and it will not go lower than 8.4 I don't know else you want you won't tell me anything that I asked you so it's hard to know I do know you need an isolation tank ask your coral reef dealer about that number one rule reefing always use an isolation tank for anything going in your Reef this is your best stance at controlling disease pasts larva and worms so if you wouldn't mind filling in the amount your tank is what kind of refugium or filtration system you're using by the way you talked about your protein skimmer it's not working correctly most of that can be controlled directly by head pressure the amount of water on top of the power head is head pressure do you know any of this how long have you been in reefing I have from my last tank corals you cannot buy anymore so where I buy my corals from they buy my rare Coral and resell it I have very good reproduction budding and splitting corals for other individuals and pet store I get all my reef Coral anything from I always Google it first
