So I have had my FOWLR tank for almost 2 years. The first fish I stocked it with aside from green chromis was a pair of Osc. clown fish. every month or so I would add another fish which some included (pajama cardinal, royal gramma, yellow wrasse, coral beauty, yellow head sand sifter...

I have a halloween crab that killed my Blue Tuxedo Urchin. I got the Blue Tuxedo about a month ago and he always cruised the tank with no woories. Last night I found the Halloween crab over it but when I noticed it, all the spikes/hair from the urchin were removed, in other words, it looked...

I quarantine all my new fish for a week or 2 before placing in my main tank. My quarantine is 10 gallons and I have read that it is not good to quarantine a blue hippo tang (Dory) due to the stress of it having to get resettled when put in the main tank. It eats good in quarantine but does...

I have 2 Clowns, 2 green chromis, 1 valencia goby, 1 yellow wrasse and 3 PJ cardinals that all I feed is Mysis and Brine shrimp. Is there some type of extra nutrients I can sub every few days or week to help them out or is this all they need? Thanks

I had my yellowhead goby for 6 months with no problem till I found it 90% eaten yesterday and found wrapped around my insert. I did purchase a Halloween crab last week and think it might of caught it sleeping at night and ate it. Is this possible? Anyone had this happen before? Should I get...

How long should a fish be housed in the QT tank before moved over to the main tank. For Example, some fish require a stable tank with algae and LR which it can graze on throughout the day. If all the QT tank has is a pot for hiding and nothing else will the fish eventually get stressed and die...

I have a missing bicolor angel fish that went missing over night. There is no way he was sucked in the filters and not on the floor so he didn't jump out. I lifted up my insert and only LR to make sure he was not wedged under but did not see anything. Could my 5 HC's have eaten it over night...

I have had 2 snails just die and be gone this last week, The shells are still there but they are not. Do they leave the shell and look for another and get attacked and eaten in the process? 1 is an Astrea and the other is a Turbo. I found the astrea upside down one day at the bottom of the...

My tank is a FOWLR and it has been running for about 6 months now. After my cycle and numbers were at 0 everything was good till about 3 months ago I had a slight spike that went up to 15 or so and I found out I was overfeeding them causing this. After weekly water changes and twice a day...

I have a 55g corner FOWLR but only have 15lbs of LR. It is sitting behind my Insert I got from Instant Reef. The tank has been setup since January and I have not had any issues with any levels. Now my question is, if I decide to add another 10-15lbs of cured LR what would be the plus on this...

Should I just get 1 scarlet cleaner for my 54g FO tank or do I get a small pair? I currently have a goby, clown and 2 damsels. Will possibly get a small flame or regal tang in the next few months. They say they do better and are less shy when in pairs. Just looking for your guys opinions, Thanks

My tank has particles floating all over the tank and the 10lbs of LR in it has a brown coating on it that looks furry/hair like. All readings are 0 and my salinity is 1.024. This started happening after cycling and my tank has been up for about 6-7 weeks. Could this be a phosphate problem? I...

I have a 54g corner tank w/ 2 power heads facing each other at the very top, a canister filter and surface skimmer. I have 2 chromis and a gold head sleeper for now and it looks as if the sand will not settle. It had settled during cycle but after cycle I turned on the skimmer and it pushed sand...

I have read books that say to top off your tank as needed with Fresh RO water. Would it be ok to top off with extra mixed water you have laying around from a previous water change? Or should that water be dumped after some time?

I read an article and some books that say to keep a QT tank at 1.016 when acclimating new fish before introducing them to your main tank. I just started my QT 1 week ago and bought 4 chromis 2 days ago to help with the cycle. 1 died over night and the others over the next day. Was this due to...

I just finished cycling and am goin to do my first water change. How long do I need to wait after mixing the salt in my vats and do I need a power head or air pump to mix it or can I just stir the water while adding the salt? Thanks!

I just finished cycling according to my LFS and the readings I've been getting the last week. I cycled with no carbon in my canister filter and without my skimmer. Is it ok to turn on the skimmer and add carbon now? Also, do i do a cleaning on the sponges on my canister filter or wait since...

Hello, I just started cycling this week, I am on day 5 and the tank still looks a bit hazy/foggy. It does not look like sand and all I have on is my canister filter with no carbon and 2 power heads running facing each other. Is this normal? How long before it clears up? First SW tank by the...

i will be setting up a 55 gallon FOWLR tank was wondering what would best fit my tank. 2 750 gph power head/wavemakers or the 1 1600 twin wavemaker/powerhead pump. If I got the 2 I would place them on opposite corners facing each other but if I got the 1 I would place it in the back corner...

I will be buliding my first SW tank soon and have begun the planning stages after months of book reading. 1 thing I plan on is artificial coral with live sand or crushed coral. My question here is, is it OK to buy the artificial corals they sell at the LFS or Petsmart? or should I just buy the...

I am doing a 55 gal acrylic corner tank with FO, artificial coral, live sand or crushed coral, and possibly not sure, a piece or 2 of live rock just to help out the cycle. I am up in the air between T5 HO 24W 10000K/Actin bulbs and the LED lights rated at 400 lumen .06W 6500K. One thing in...
