I just add the water the way it is most of the time. I check the salinity which is 1.0245 almost always and adjust the temperature. Sometimes I run it thru carbon but not always.
Also I am not the only one on the East end of L.I. that does this.
I don't have any SPS , if I did I might not be doing things this way.
All my corals are pretty easy stuff..mushrooms, LPS,Favia,cup,acans,trumpet
I've had reef tanks since the late 80's 2 many 2 mention LOL. So I'm not new to this hobby by any means. One thing I have learned is most things are controversial... Skimmer,no skimmer, sand beds,no sand beds, lighting etc...etc..and what works for one person doesn't work for everyone.
What has been brought up in this thread is valid and is exactly what I've heard for 5 yrs.But.. That being said ...for 5 yrs this has worked great for me and my tank.No buying salt, no mixing , once I get to the Inlet it takes 10 minutes and I have 20 gal of salt water. Of course I am lucky enuf to live near the inlet which really helps alot..
IMO.. I don't believe you have to go 2 miles off shore to collect water..But that's my opinion...Where I get my water is flushed in and out every day at the Inlet. I live 2 blocks from the bay but I would not take water from there ever.I have talked to Joe from Atlantis years ago ,when I was a member of LIRA , about collecting water at the Inlet near me and he said if I remember correctly that I could mechanically filter it if I wanted but it should be good to go the way it is.
As far as fish...I have 4 Gobies , 1 Clown, 1 File Fish, 3 Chromies not much in the way of fish but to be honest , I wouldn't have any if my wife didn't make me get them. I've had them for years ..never had a case of ICH.
ICh , another controversial subject..LOL
Bottom line is that this has worked out very well for me but like I said if i didn't feel comfortable, I wouldn't do it. If at any time I thought my corals or fish were in trouble, I would have stopped immediately.Granted I only have 9 fish but at no time have I seen a problem.
Let me end this with.....Can anyone say that that since they mix their own salt water they never have any problems with their corals or fish..If so I'd like to talk to them. LOL
