So i have been looking up care for my zoas from the frag event and there were several mentionings of iodine suppliments,i am wondering; how do i know if any suppliment i add will adversly effect any of my other coral/inverts/and or fish?
I personally wouldn't add anything to supplement zoas. They are hardy corals. Just feed your fish and they will get what they need.
Lugol's Solution is a great iodine/iodide additive. That being said, 99% of aquarists don't need to supplement iodine, and none do it without having a test kit to make sure you don't over do it. I wouldn't worry about adding it though, just keep up with water changes and you should be good to go.
Your inverts such as peppermint shrimps can benefit from iodide, it helps them molt. I use idode for my softies and inverts, it helps bring out the color of zoas and palys a little bit, and thats about it.
I just got a hand full of snails to help with some of the algae in the tank and they are going to town. though there is one type of algae i don't think they're touching and I don't know if its Coraline algae or something I need to be concerned about...
It is red slim algea. If they dont eat it soon then kill the lights for a couple of days, it dies off easier than other algeas. most hermit crabs and snails will not eat the algea. Check your phosphates would be the best thing to start at.
I agree with Andy, red slime (cyanobacteria). I'd suction out what you can. It usually comes off in sheets. Definitely work on your nutrients, but having good flow and good lighting will inhibit it's growth, as well. I tend to see it in my tank when my T5 bulbs start to get old.
The trick with red slime is that you can treat and remove it all day long, but if you don't correct the cause of it to begin with it will keep happening, such as old light bulbs, over feeding, not enough flow or filtration etc...
fluval has an phosphate absorbing media but no instructions on the packaging as to how it is used, i'm assuming it goes into a canister filter. would it be worth investing in a canister for a 29 gal tank? those are the ones that caught my eye any way. thoughts ?
