been dosing with iodide.... bad news...

I would do at least a 50% change. Then another one the next day. By doing a 5g change you just essentially diluted it very little. If there is something in your water killing things you need to get as much water as you can out and replace it with new water. If you are taking straight sea water then I don't even think you should be dosing at all honestly. I have even heard stories of extreme cases were people will flat out drain their tank and fill it back up with new water.

 

man your luck you live in the keys and your clser to the water than i am i have a 15min ride to the closes beach and 30 mins to my boat its just not worth it for me to carry jugs around lol

I would do two 50 percent water changes spread over 3 days and run some cardon if you can.

 

LOL

If I was that close, I'd make it worth the trip by carrying several 5g buckets.

Agreed, the more, the better... and running extra carbon will help.

 

so 5gallons is not....

understood ....tommorrow i will go out at high tide and do a 50% water change then i will do another 50% water change a few days later. i am so lucky i guess that the ocean is my backyard .. good for water changes bad for huricanes lol.. But i do understand what to do and i will follow your tips as to what to do it seems like a 100% of my water and carbon needs to be done.. does it matter that i have a dsb about 6 inches .. should i disturb that or should i just replace the water.. meaning should i collect new sand from the ocean again.. i really hope not......tnx

 

No, you should not disturb the sandbed.

 

My first SW tank was 100% water from an incoming tide,
taken from the Boynton Inlet, Boynton Beach, FL.

I too wish I still had that luxury too!

All my live stock was caught also- 'Slurp Guns', and nets while snorkeling or S-diving.

French angels, blue angels, puffers, stick fish-found in tidal sea weeds, etc.

 

i will not...

i will not disturb the dsb .. guys,, thanks so much.. really i mean it , i love this forum and rely on people like you to help me out.. tnx... i will do an 70% water change tomm and rund extra carbon ..... if you guys have any more tips please feel free to let me know i will follow them to the letter..

 

I live right off the ocean here in Daytona. Every weekend I go down to the beach and take 4 five gallon buckets full of filtered salt water home with me. 20 gallons/week. That's my water change. Been doing it for 7 months, and everything is fine........

If I lived in Colorado, I'd buy RO, and bags of salt, but I don't. I live in Florida, and what I do works great. I recommend it to anybody near the coast.

 

and + 1 on Mr. Bill's "Do not disturb the Sand bed" There are bacteria there you dont want to loose. As well on the high tide water grab, be sure to use a clean pillowcase inside of your bucket as you catch the water. It will keep any floating critters out of your water in case you want to store your catch for later days. If not, they will simply turn into ammonia if you store the water. Believe me, there are more things in natural sea water than you and I think. best of luck with everything.
