    blue hippo tang help

    These very small hippo tangs have become very common in the trade, despite the fact that silver dollar-sized hippos have a very poor survival rate in home aquaria. If you have the room (125 gallons, at least) wait for a somewhat larger specimen to become available.

    Help with clownfish!

    There are so many possibilities for your Nemos' death, so we will need much more information. What size tank, filtration, parameters (s.g., ammonia, nitrates, pH, temperature, etc)? When were the other fish added? Were they quarantined? How often do you top-orr? change water? Once we know...

    christmas wrasse

    Christmas wrasse are great fish - hearty and peaceful. This was the first saltwater fish I ever had, and that was 37 years ago. It lived for 2 years, at a time when if a marine fish lived for two months people came from all around to see how you were doing it. I still miss that fish.

    need some help

    To get these two to co-exist peacefully in a 125 gallon system you will need two things: first, lots of rock so that each can have a territory and a place to hide; and second, a tremendous amount of luck. Sometimes two fish will just kill one another, and yet an other pair of the same kind will...

    RO water or ro/di

    RODI is noticeably different from RO water. Just try drinking RODI - it is considered to have a bad taste because there is nothing in it that is detectable to our taste buds. OTOH, RO is what you get in bottled water becasue it tastes good - there are still dissolved salts in it that give it a...

    Quarantine

    Using water from an established tank won't work. The bacteria you need to detoxify nitrogenous wastes are not in the water column - they only grow on solid surfaces. Use some filter material or rock from your established tank, monitor daily for an ammonia spike, and keep something like Amquel+...

    Quote: Originally Posted by Flower I always thought: Even fake decor will have enough good bacteria for a fish tank to thrive.

    is it possible to have cold water live rock in a tropical marine aquarium?

    What do the live rocks in Newfoundland look like? Desirable live rock is highly porous to give the anaerobic bacteria plenty of surface to thrive and convert nitrate into nitrogen (see Fiji rock for a good example).

    New to hobby and researching

    Coral off the bat will die if your cycling. Live rock and cycling go hand in hand. I recommend a few small fish and live rock. Cycle tank and then over time try your hand at corals. Corals can be very expensive and need stable chemical, lighting, and salinity. All of which makes for...

    Cloudy Water

    You said " two powerheads in the tank. One providing bubbles and the other current". Bubbles are not good in a marine tank, but current is. I would eliminate the bubble function, and get that powerhead to provide only water movement. Look at the water column closely - is the cloudiness due to...

    Lost my last Chromis

    I think chromis are much harder to keep than their description would lead us to believe. Over the past 6 months we have tried more than 20 chromis in small groups (2-3) and larger (7), trying to get a school of 7 for our 220 FOWLR display. Of all of those fish, only 2 made it through...

    need help please thanks !

    First, how do you know it was ich? I find that most hew hobbyists tend to call everything that leads to fish death "ich". What were the symptoms? If it does turn out to be ich, then the only way to rid your display of ;this parasite is, as mentioned earlier, to leave the tank without...

    New to hobby and researching

    I am not a fan of so-called "nano tanks". While a smaller, less expensive tank seems attractive as a starter tank, such tanks are actually more difficult to maintain because their small water volume makes them less stable. As a result, animals die, and new hobbyists give up. Given sufficient...

    Diatom bloom crazy in new tank, Live rock......

    Here's how you can determine whether you can use tap water in your tank: call your local water company and request a copy of their most recent water quality test results. If the person on the phone says they don't have it, be persistent - they must do the analysis under law. If the analysis...

    New 90 Gallon Tank, my first time with Saltwater!

    You mentioned that you are replacing evaporation with tap water to keep the salinity constant, but using tap for this is a major problem. While the water does evaporate, the hundred or so contaminants in tap water do not - so as you continue to add tap water you are continually increasing the...
