Need some help!!! :)

[nittinid]

I HAVE A COUPLE QUESTIONS HOPEFULLY SOMEONE CAN SHINE A LIGHT ON ME...IVE BEEN DOING A LOT OF READING ON BACTERIA AND I WAS WONDERING IS TO MUCH BACTERIA BAD? THE REASON I ASK IS BECAUSE IM RUNNING 2 FLUVALS A 105 AND A 405...AND IM NOTICING A LOT OF LIME GREEN ALGAE.
MY TANK HAS BEEN UP AND RUNNING FOR 9 WEEKS. THE FIRST 7 WEEKS I HAD NO FISH OR INVERTS IN THE TANK. 2 WEEKS AGO I ADDED 2 FISH ..SAILFIN TANG A YELLOW TANG AND 4 HEMIT CRABS...AFTER 2 DAYS MY AMMONIA WAS STILL AT ZERO...SO I FIGURED EVERYTHING WAS GOING GOOD...I DECIDED TO ADD 2 MORE EXTREMLY HUGE HERMIT CRABS AND A GOBY...I ACCLIMATED THEM FOR 8 HOURS...DUE TO THE FACT THAT THE PET STORE HAD THEIR SALT LEVEL AT 1.017 AND MY SALT LEVEL IS 1.025.I DONT KNOW HOW THEY SURVIVED IN THAT LOW SALT GRAVITY,GO FIGURE.
I WOKE UP THIS MORNING TO FIND THE GOBY EATING ALL MY ALGEA(GOOD THING)BUT ONE OF THE HERMIT CRABS HAVENT COME OUT HIS SHELL SINCE I PLACED HIM IN THE TANK.I KNOW HEMIT CRABS AS WELL AS ALL INVERTS ARE SENSITIVE TO WATER CONDITIONS,WHICH BRINGS UP MY NEXT QUESTION...WHAT CHEMICALS ARE NECESSARY IN THE WATER TO KEEP THEM HAPPY? IVE READ IODINE IS VERY IMPORTANT TO INVERTS...BUT AM STILL A LIL FUZZY ON THE SUBJECT...CAN SOMEONE PLEASE SHINE SOME LIGHT ON THE SUBJECT...PLEASE..
THANKS FOR YOUR TIME AND FOR READING...

well first, i would not be running canister filters on a marine tank. id get rid of those and get a nice sump or wet/dry. next, what are your water pars? like phosphate? what kind of lighting do you have? what kind of salt? your tank is still very new. dont be going crazy yet with a hermit crab dying or anything. your main issue right now are those fluval nitrate factories you have. getting a better free flowing system will be better. speaking of which, what about power heads? how many and what are they? the more flow all around the better...

HEY THANKS FOR THE QUICK RESPONSE..THIS IS WHAT I HAVE IN MY TANK..

90 GALLON DISPLAY
IN DISPLAY;
110 LBS FIJI LIVE ROCK
85 LBS LIVE SAND
(3) 50GPH POWERHEADS (AQUA CLEAR)
30 GALLON SUMP

AND MY LEVELS ARE

SALT 1.025
AMMONIA 0
NITRITE 0
NITRATE 5...ITS NOT ZERO AND ITS NOT QUITE 5PPM

AND AS FOR MY LIGHTS...I HAVE T5s (SIX BULB FIXTURE) I KEEP THEM ON FOR 8 HOURS A DAY. THEN I PUT THE DUSK LIGHT ON FOR ABOUT 2 HOURS AND THEN I PUT MY LUNAR LIGHT ON WHEN I GO TO SLEEP....ANY THOUGHTS THAT THIS MIGHT BE A FACTOR?

Why are you running canister filters if you have a sump?

 

[nittinid]

Well i experienced a mini cycle when i upgraded from my 30 gallon nano to my current 90 gallon...and i added the canisters to help my l.s at the time.
I just kept them in there to help build more good bacteria.in time though i plan on taking them out....just need my tank to mature a lil more...

 

[125reefer]

will this be a reef tank or a fish only.cannisters are fine for FO tanks.and a small reading of nitrates wont be the death of fish.its a reef tank you need to worry more about nitrates.

 

[nittinid]

Im still debating if i want corals or not.i was leaning towards a reef,but all the fish id like to add to my tank aren't reef safe.why do all the beautiful/exotic fish have to be coral pickers....grrrrr...
