Could use some advice (What would you do...?)

Hello everyone,

Some Background:
My name is Nick and I have been lurking through the threads of reefcentral for a little over three years now. Two years ago I took the plunge and purchased a standard 90 gallon reef-ready tank with the hopes of running a successful reef aquarium. The tank was set up 6 months later (once I moved into my apartment) and has been running for roughly 18 months. I have recently encountered some problems and could use some advice.

The Problem:
Over the past 6 months i've been experiencing excessive algae growth and coral loss. To add to the mix, I noticed ich on my foxface today (more on this in a bit). I understand that usually uncontrolled algae growth is indicative of poor parameters, but I have been testing mine and getting consistent results within the normal recommended range. The parameters of the tank (tests taken today) are:

Salinity: 1.025 (refractometer)
Ammonia: 0ppm (API)
Nitrite: 0ppm (API)
Nitrate: 5ppm (Red Sea)
Calcium: 440ppm (Red Sea)
Alkalinity: 8.5 (Hannah Checker) and 8.3 (Red Sea)
Magnesium: 1300ppm (Red Sea)
Phosphate: 0ppm (Hannah)---I understand this may be misleading because of excessive algae growth.

Equipment:
Lights: Pacific Sun Metis Hyperion R2 LEDs
Skimmer: SWC 180 Cone Skimmer
Water Movement: 1 MP40wes and 2 Koralia 1400
Controller: GHL Profilux III
Dosers: 2x BRS 1.1 mL/min Dosers--controlled by Profilux
Reactors: I use a BRS dual reactor filled with BRS high capacity GFO and Carbon ROX-changed once a month
RO/DI- BRS 5 stage delux--always reads 0 TDS, filters changed regularly every 2-4 months or as necessary.
Sump- custom built 30gal with ~15 gallon refugium filled with live rock and chaeto
ATO-JBJ and aqualifter

NOTE: I have roughly 80 pounds of live rock~70 of which was BRS dry reef saver rock and 10 pounds were live rock added to the refugium to seed coralline and bacteria.
20 gallons of water are changed roughly every two weeks.

More on my ich situation:
**7 months ago**
All fish that were added to the DT were quarantined in a separate 20gal QT for 6 weeks to ensure they were eating and free of disease. This rule was ignored for a CBB that was added to the display tank to encourage eating of live pods on the live rock. Well, the inevitable happened roughly 1 month later and I lost several fish due to ich. I removed the CBB, foxface, the last surviving anthia and the royal gramma back to the quarantine tank for copper treatment and observation while the tank went fallow. The tank was left fallow for 4 months (intention was 2 months but I took 18 credits of classes over the summer and become a wee bit busy). So, after the two weeks of copper treatment (I used cupramine and ensured my copper levels were at 0.5 mg/L with a red sea copper test kit) and a 4 month fallow period, the fish were added back into the display tank.

During the fallow period, I continued to feed my RBT anemone frozen mysis once a week. Roughly one month into the fallow period, I began to notice diatoms growing on the sand and live rock. I reduced my photo period and changed my gfo media. This didn't solve the problem. The diatoms continued to grow and eventually covered most of my rock and sand.

My logic:
Even though the fish were removed, the system was still being fed due to the larger RBT that I was still feeding once a week, which should prevent excessive die off that would cause phosphates. The only thing I was adding to the tank was my 0 TDS topoff water, but I suspected possible phosphate leaching anyways. I tested my RO/DI water (stored in a 32g BRUTE can) and felt closure once the phosphates were measured to be 0.08-0.1ppm (I performed the test 3 times). I proceeded to buy another reactor from BRS and filled it with GFO to set the phosphates back to 0. Now all topoff water measured 0 phosphates when added to my topoff reservoir.

**Present Time**
Still battling the diatoms and as mentioned earlier, I noticed ich on my foxface again this morning. :( I have refilled my quarantine with salinity-matched saltwater and plan on pulling the fish this weekend to begin another treatment of copper and another fallow period.

My Questions and Options:

1)Any ideas on what could be causing my algae outbreak? If I am missing any information that may be necessary to help with my situation please alert me. One idea I have is that perhaps my dry rock has reached a layer rich with dead organisms that are now leaching phosphates into my water.

2)What caused the second round of Ich? My only suspicion is a small frag of duncans I added about 2 weeks ago to test the stability of my water parameters. For the record, the duncans look great but my small $10 test frag of sps does not. Perhaps the Ich was on the frag mount as a protomont or tomont?

3)A plan of action. Hopefully, with the help of this community, I can find the underlying cause of this problem and address it appropriately. I have considered pulling the fish, sterilizing my rock and replacing the sand...essentially restarting but this is something that would have to be a last resort option.

Not sure where to put this...but I feed my fish three times a day. In the morning I feed them pellets. In the afternoon I feed them LIVE blackworms kept in a blackworm keeper in my fridge (water changed daily with de-chlorinated water). In the evening, I feed them pellets again. All servings of food are small and I can see them eat 90-95% of the food (some gets away and is presumed eaten by CUC or pulled out by my skimmer).


I truly appreciate you spending your time reading this thread and am open to any suggestions.

Best Regards,
Nick
 
Generally, a full month of copper is recommended for ich.

Are you sure it is ich? All sorts of mild irritations like scrapes or stings can causs a white bump. If there is only one bump on one fish, I'm not sure it is ich.

How often to you clean detritus from the rock and sand? How often do you do WCs? How well is your skimmer working?

It wouldn't surprise me if you have enough detritus built up on the rocks and in the sand thay both have become a bit "clogged", which can lead to WQ problems.

You mentioned a fuge with LR, are you careful to frequently remove detritus from it? In sump fuges with LR rubble often turn into what is effectively a settling chamber, leading to a build up of lots of decaying organic gunk.

Just got back from class, the CBB now has 4 white bumbs on one of its fins, and the foxface has 2 more on its side. I double checked with some pictures and i'm certain it's ich. Thanks for the note, I will treat with cupramine for 4 weeks this time. Should this treatment be 4 weeks back to back? Or how long should the time in between treatment be?

Good ideas, I must say that vacuuming the sand is something often overlooked during my maintenance routine. This weekend I will add the fish back into quarantine and do a rather large water change to vacuum the sand.

As I mentioned, 20g water changes are performed bi-weekly. The skimmer has been performing great and it is cleaned every 4-5 days.

Thank you for the response :spin3:
 
I didn't see anything about a clean up crew....
What do you have for your CUC???
My general rule is 1 cleaner per gallon and snails would be your best option if diatoms are the problem... (big fat turbos are cheap and will do more work than their 1 gallon share)

Oops, forgot to throw this into my original post. I ordered my cleanup crew from reef cleaners and got the basic recommended package for my size aquarium, which is:

roughly 80 dwarf ceriths
30 nassarius
30 florida ceriths
30 nerites

I then added 15 blue hermits + various shells to reduce the likelihood that they fight eachother for larger shells.

I will check my LFS for some turbos to keep the diatoms at bay, although I'd like to find the underlying cause more than anything.

Nick:

I hate to say this, but your fallow period on your Display Tank seemed to be about 5 weeks too short. See this thread for an excellent discussion on ich:

http://www.reefcentral.com/forums/showthread.php?t=2041951

I recently fought a bad outbreak of ich in one of my 250 DT's, and left it fallow for 10 weeks just to be safe. I made a similar mistake by adding a wrasse I didn't quarantine.

I can't help you with copper treatment, I treat my fish with hypo salinity. The fish in my 250 that were infected all recovered nicely in hypo, some of them were in pretty bad shape.

It might be helpful if you posted some photos of your tank. I used 100% dry reef rock in both my tanks, and fought diatoms and hair algae for about 10 months. It's finally settling down.

Your parameters look fine, how are you maintaining your calcium levels?
