Hi all, For years I have had a 450 gallon FOWLR acrylic tank. As you can imagine, this is a very large surface area to keep clean. I was using a Mag Float rated for my 3/4" thick acrylic. This worked fine for a long time. I more recently have a much more stubborn algae that would not come...

Hi all, I have a large 450g tank with plenty of LR. The tank has sort of evolved into a more aggressive setup. I have plenty of room to add more fish. Currently there is only a Snowflake Eel, Foxface Lo, Mono, and Lunare Wrasse. I want to add more fish and since I am not doing corals I do...

I have a 450g tank with about 380 lbs of LR. I have an Atlantic Blue Angel (I think that is the proper name, I'll attach a pic) that has lost much of its color and his fins are getting ragged looking. He no longer seems to be eating and just hangs in the lower back corner of the tank. I am...

Hi all, I have had an Atlantic Blue Angel in my 450g FOWLR with 380 lbs of LR. I would like to add another Angel to this tank. Can I get some experiences from everyone who knows which other Angels can peacefully coexist with my Atlantic Blue. Also, I put a Lunare Wrasse in this tank about...

I have a large FOWLR tank with plenty of LR. I have one of the Coralife fixtures that have blue actinic lights and MHs. I have been mainly running the blue actinic during the summer and now I have been putting the MHs on. When I put the MHs on I realized that the tank hada greenish appearance...

Hi all, I searched AA on the topic of pilot fish and came up with very few posts. The only warning I saw was that they get very large. I recently purchased 3 pilot fish for my 450 gal FOWLR. I put them in QT with a Yellow Tang and I was planning on acclimating them for a few weeks before...

Hi, I have a pump that I keep in a large vat of fresh water. Every few days I turn the pump on in order to topoff. I have a large 450 gal setup so I loose alot to evaporation. Also, my sump is in a hotter room than the main so I keep one of the panel complete off the top of the main. I...

Hi all, I have 6 emerald crabs that I introduced to my 450g FOWLR tank. There is about 380 lbs of LR in this tank. At first these crabs were very lively and not at all timid. After several weeks I realized that they have started to withdraw. There is no sign of them anymore. I thought...

Hi all, I have a cycled 29g tank I use for QT. However, I have not had fish in this tank for a few weeks. I am concerned that the lack of a source of ammonia would cause a destruction of the aerobic bacteria. I am quite certain that this would happen eventually, but what is the general...

I have a gasping fish that I think is a result of high nitrites. How well do fish recover from this scenario assuming I get the levels down fast? Thanks, Pete R.

I have to replace a return pump. I am thinking about a Dolphin AS2700 (1.5" outlet) or a BlueLine HD70(1" outlet). The return water will go through a short run of 1" hose and into a UV stelilzer and out to 1" hose. It will then be split an reduced to 3/4" hose that rises about 4 feet to the...

Hi all, I always practice QT before introducing new arrivals into my main. My question is: Are there any considerations when QTing a bottom sifter like a Sleeper Goby in a QT that has no substrate. When I feed the other tankmates in QT they eat "normally" but the goby does not seem to be...

Hi all, I have not yet added many inverts to my main tank. I can't seem to get a good handle on how people try to minimize introducing parasites from the inverts (mainly snails and crabs). I have been very disciplined at QTing any new fish and this has proven to be very benfeficial. I am not...

Hi all, I was wondering if anyone could give me some feedback on purchasing snails and/or crabs on ebay. There seems to be some good deals on large volumes of snails and crabs but my skeptical side says to be careful. Please pass along any successes and/or disappointments. Also, any sellers...

Hi all, I have a layer of green algae on my substrate that I guess I let go too long. When I am syphoning the gravel the algae is sort of clumping up and not easily being removed. If I am planning on getting a clean up crew should I not worry about this? Thanks, Pete R.

Hi all, I have a Clown that clearly has Popeye in one eye. Please see my specs in my signature. Since this is such a large setup I am thinking that he will recover on his own. He is able to eat and is not being harrased by tankmates. My water parameters are all ideal. What do you all...

Hi all, I am disinfecting a QT that had sick fish in it. I want to get the QT nice and clean and ready for new arrivals before putting them into my main. I am comfortable cleaning everything in the tank with bleach, but I am not sure if I should bleach the biowheels. Will this ruin them...

Background info: I introduced a Yellow Tang and a Copas Tang into QT right after purchasing them. I have been very vigilant about quarantining all new arrivals and I am yet to have an outbreak in my main. I immediately started hypo, gradually lowering the sq to 1.009. Everything looked good...

Hi all, I have been in search of a formula or formulas to calculate a desired sg of saltwater given a known volume of water. Does anyone have one handy? I use Oceanic (the blue bucket) which gives a rough starting formula of 1/2 cup of salt per gallon to achieve normal sg, but often I want...

Hi all, In trying to do the right thing, I recently changed from a 10g QT to a 29g. I had a basic small Whisper filter in the 10g with the standard bio foam block and the charcoal puch. I had no trouble keeping Ammonia and Nitrates down with a Yellow Tang in this tank. So I assume the foam...

I have a Yellow Tang and Scopas Tang in a 29g QT. I have a very large main FOWLR tank that I can't risk contaminating. The fish looked great when I got them and I began Hypo (sg = 1.009) which they have been in for about 2 weeks so far. Just yesterday I noticed the Yellow Tang had a few large...

Hi all, I have an AquaC EV-1000 and I was wondering if anyone with this model or a simialr one has had a similar experience. When I adjust the water level in the skimmer using the exit gate valve I seem to get foam production when the level is a few inches up the cylindrical column...

I have been shopping around for an auto feeder for my large acrylic tank. My acrylic tank has a small cutout for feeding on the top, otherwise there is no other place to put one. All the feeders I have seen seem to be the type that clip on to the back or side of the tank. Are there any...

As I've mentioned on other posts, I have a large tank with 380 lb of LR. In the event that my main gets infected my only treatment option will be Hyposalinity. I know that Hypo will kill all inverts, and I think my coralline will be affected as well. If I treated for say 4 weeks can I...

I am setting up a 29gal QT. I am torn between getting an Emperor 400 Bio-wheel or a Whisper 30 filter. I have heard good things about the Bio-wheel but I have used a smaller Whisper in the past and it worked well. Does anyone have any suggestions which might sway me either way? I assume the...
