big problem!!! =( plz help

hey guys and gals.... i got a problem but have no idea what it is...

my tank has been going for about 5 weeks

all the lvls look normal 0, 0, 0

what a good ph lvl? mine is at 7.8 probably to low?

salinity 1.023

the sand i bought first and put the live sand over is turning black in one area =/ anyone know what thats from and if its bad?

couple days ago my blue hippo tang died =/ he had been in the tank about a week and was doing fine.... swimming around... eating... ect. and one morning i woke up and he was just lying down on the sand and he was dead about an hour later.

the next day my spotted damsel (er whatever its called) i found in half in the back of my tank.

today my maroon gold striped clownfish is looking rather sickly and hasent eaten for 2 days, also looks like he may have a little bit of fin rot on one fin.... he looks like he is gonna die soon =(

is there anything i can do to help him?

also my striped damsel lookes like he is breathing very hard.

i have a descent amount of inverts... 1 serpant star, 1 cc star, 2 emerald crabs, bout 10 snails (who seem to be multiplying rather fast) about 10 little crabs, and the other day i got this little slug thing that looks like walking algae and a decorator crab (not sure if thats his real name, just what the lfs called him) he looks very camoflauge and sorta like a spider.

is there any way the decorator crab could have anything to do with this?

i think ive been feeding them the right amount.... i got these little packets called tetranatures delca whole brine shrimp and bloodworms which i feed about 3/4 of the pack a day. they gobble it up pretty fast, probably in about 3 mins but there is always some left on the sand.

also , do feather dusters need special light?

thx so much guys/gals

That is most likely your problem right there. MArine aquaria requires a ph of 8.2-8.3 on average. If after doing a water change you have seen no possitive results, then I would suspect inadequate water flow (GPH) and/or a covered tank. Sometimes if the room does not get a fresh supply of air, ambient CO2 can also lower ph. Opening a window will cure that.

At 5 weeks it is most likely a diatom or other nuisance algae. If it's vevelty and slimey to the touch, it could also be cyanobacteria. What is your source water?

The tang, damsel and clown have most likely succumb to the low ph and quite probably low O2 levels. FWIW , a tang is not a very good choice for a new tank. They are best added after 6-12 months to allow the tank to stabalize and mature.

More info about the tank set up and your routines would be good

If the fish where not able to defend themselves and get away, then yes but otherwise healthy fish should be of no concern.

IME, these foods are a very poor diet for marine fish. Bloodworms, brine and water fleas are not the greatest source of nutrition. I would suggest a high quality fortified marine flake food, sinking pellets and other foods designed for marine aquaria.

They can live in a dark cave providing they get enough water flow to provide food.

Cheers
Steve

is there any around the house material that would be safe to add to raise the ph?

None that I would recommend at this point. Before trying to "add" to the problem I would suggest some additional feedback from you about the points I made above.

The solution may be simple, but not without some more info from you.

Cheers
Steve

im pretty sure my water flow is ok, i have one powerhead that says it good for a 50 gallon tank and mine is 35, i also have some sorta filter i picked up that looks like its helping to add to the flow. i have about 8 lbs of live rock, about a 3" dsb, and a heater.

i know thats not a very good setup but im only 17 and make about 60 dollars a week hehe.... i plan on getting a protein skimmer next, and some more live rock.

i know its bad but ive been using the filter on my tap water for the water... i add the dechlorinator. soon as i get some money im gonna go buy the ro water from my lfs and do a big water change but i dont get payed til' thursday =/

Is this pump located at the surface or near the bottom? IME this is very very low for a marine tank. The GPH of the tank should be a minimum of 210-250 GPH for a 35 gal tank

Hang on or canister? Do you know the GPH ?

Great choice

You still have not said if the tank is covered/sealed in any way?

Cheers
Steve

the filter is a hang on, not sure about the gph.... it isnt covered=/ are there covers i can buy for it that will fit it?

the powerhead is at the top.... is it safe to bring it down to the bottom and submerge the cord in water? it has a little thing to hang it on the top so i just assumed thats what i do.
