Introducing New fish/ Algae Problem

[Ibby]

I have a 100 gallon Acrylic tank. Been set up for 3yrs now. was all choral (and then we had 2 babies) since I have switched to fish only. Water checks out OK. Salt level @ 1.023. Temp 76. Sand. Sump and protein skimmer underneath.

First. everytime i intro new fish I lose one. Mostly the newest ones. Is there anything I can do to help this process. I float the bag, let in a little water and let it sit for a good 20-30 min.

Second. My Live rock is starting to grow A LOT of algae. I recently moved them? could this do it? I want to get some cleaner fish, any rec? My yellow tang passed away a few months ago (had him for 3 yrs) and my sailfin tang doesn't seem to eat too much. I have 2 choc chip stars. :HP I lost my Koarn angel only 2 weeks after i got him. I am sad and don't want to lose any more fish :confused: :confused:

thank you

What are your amonia, nitrate, and nitrite levels?

Do you have any crabs or snails

You should consider
a), Allowing them to drip acclimate which is: Pouring the new fish in a bucket (5 gallons is good) and run a peice of airline with a valve into the bucket and tape them or attach them in the bucket and tank so that they won't come lose and just use gravity to syphon some water from the main tank into the bucket and it will slowly match the water params the same as your tank, thus reducing stress right?
b) The other option would be a quarantine tank maybe 20 gallons with a little protein skimmer, power head(s),some live rock, and bare bottom. Lighting could be minimal and would suffice with N.O. (Normal output) Florescents, as bright lights will add to the stress the poor animal already has. With the quarantine you could keep your new fish for a few weeks untill you are satisfied that they won't perish, and that they are not sick.

HTH!

I had the same problem. I would float the bag, introduce 2 or 3 small fish and at least one of them would die every time. The LFS, SeaHorse Aquarium Supply, has a website with a great explanation of a dripline as well as a ton of other information. Cut and paste the URL below into your browser and select "SeaHorse Tips. Scroll down until you see the picture of Cyano bacteria on the live rock and it is the next tip. Woody also has a write up regarding quarantine/hospital tanks that is definitely worth a read. There is a lot of stuff on his site, not all of it mainstream but all of it worth pondering.

I hope this helps. I have not lost a fish since I started using this method.
