Mayday...Mayday

I need some serious advice before I spend some $$$ or cause massive stress on my tank. This will be a little long but if you can endure, I appreciate your comments and advice.
Tank:
Our 55G tank has been setup since 9 Sept 02. We started with water produced by an Aquarium Pharmaceuticals Tap Water Filter, this lasted till about Feb 03, when we switched to distilled water. That got expensive and we have been using RO/DI water since mid-March 03. We have 260W PC/VHO. We have an in sump Pro skim, heater, nitrate sponge. We have six power heads in the tank that produce good circulation, however some dead spots. We started with about 15 lbs LR and 50 pounds of base rock (package from LFS) and a SB of about two inches, later increased to 4-4.5 inches.
Sig. Problems/Observations:
We had a nitrate spike in late Jan, which has subsided but never returned to what we consider normal levels.
We started getting what we considered a lot of green algae growth early on. Out LFS, (since changed) said it was OK. We now have a raging green algae problem and hair algae (patches all over the rock that looks like bushy broccoli heads).
We understand our bio-load looks excessive but the fish are small, Tangs under 2-2.5, all others 1-1.5, except blenny. He’s 3-4.
We have lost about 5-10% of our snails, each month. Mostly astreas, some Mexicans.
We will remove the chromis, tomato clown and blenny when we find a way to do that. We’ve tried traps, nets, and more traps. All to no avail. Since we may remove the LR to replace it we will remove the fish then.
What we are thinking of doing:
Replacing all rock with cured LR from a LFS. Boiling the current rock to kill hair algae, and everything else, and returning the good pieces to the tank to become LR.
Remove chromis , tomato and blenny and sell/return.
Refrigium ??? (need help on how and why)

is the filter strong enough do you over feed the phos might be one of the problems you need to lower your phos to 0 and your ammonia and nitrate or trite to 0
 
We feed once a day about a .25-.5 inch square of blended variety of fish foods. Very little is left after a minute or two. All is gone after five minutes. We used Phos-zorb for about two weeks and our phos went way up, so we took it out.

You don't have enough biological filtration for the fish load. A tank that has been set up since september should be fairly stable, and should definitely not have any ammonia in it.
Getting a lot of cured live rock and replacing the base rock would be a good start.

I seem to remember you have been having problems with you tank for awhile. The best advice I can give you is to do nothing. Test for all tank parameters on a weekly basis. Feed a little less..It is fun to see our fish eat alot, but it is not necessary. Set up a regular water change schedule. Pull out the hair algae on days you do water changes. Your no3 and po4 problem is trapped in the hair algae. Do not add any livestock. Do not add any chemical or aditives except those to maintain alk and ca. if necessary. Allow your tank to mature and to become stable. As long as you keep trying new remedies and changing LR your tank will not be stable. The hardest thing to learn in this hobby is patience. Try my advice.. do alot of "nothing"

That yellow tang of yours should be eating that algae like a mad fish! I put anything green in my tank and he tries to eat it:eek:

By boiling the lr you have now you will kill any beneficial bacteria as well that are responsible for helping break down excessive nutrients. Just remove it and scrape it off with a toothbrush.
Adding more lr should help though . A refuge has worked wonderfully for me. No more hair algae in the main tank, thriving pops. of copepods, and 0 nitrate readings. Try a search on the subject and you will find tons of info. I
