    Whats the Best DIY RO/DI to install?

    Take a look at the Reef Typhoon system at AirWaterIce. I have been using their systems for many years and find them to be reasonably priced, durable and very effective.

    your filter pref ?

    I think the most impactful advance in the past several years has been the use of macroalgae in FO and reef tanks. You can just put some into a sump or an isolated part of the display tank or, as I do, use an algae scrubber. Macroalgae really do a great job of cleaning up the water, and your...

    water quality / alternatives

    You probably can't get "distilled" water. Distillation involves heating the water to steam, then fractionating the steam by condensation and saving the purest fraction. It is an expensive process since heating is involved, and the water is only barely adequate since distillation doesn't remove...

    Fishless cycling of tank with raw shrimp

    Don;t worry about old school. I set up my first tank in 1972 using an AquaKing HOB and undergravel filtration. Wet/dry filtration was state of the art to me. I still use wet/dry, but have added algae turf scrubbing because it makes sense to me as a biologist. Fish will tolerate a lot, but it...

    once live "dead " rock

    There is no need to cure the rock. Curing is used after live rock is shipped. During shipping there is a lot of die-off in the rock, so curing will allow the natural decaying process to complete before you add the rock to the tank. It can't hurt, but isn't (IMHO) really necessary. Bleach...

    Fishless cycling of tank with raw shrimp

    The whole goal of cycling is to provide ammonia to nourish nitrosomonas bacteria, who consume ammonia and convert it into nitrites (which are also toxic to fish). However, nitrates are consumed by another bacterial strain (nitrobacter), and converted into nitrates, which are far less toxic. So...

    your filter pref ?

    As folks on this site will tell you, I am old school and am running my 220 gallon system with a wet-dry filter. They work fine for FO tanks since they are highly aerobic and as a consequence can produce some nitrate. Generally, if you keep up with water changes this isn't a problem for fish...

    Why do my fish keep disappearing?!?!

    There are so many problems with your system that I hardly know where to begin. I have a 30 gallon tank that is about 4 weeks old now (not completed the cycle yet), but I started with fresh saltwater and sand from my local beach (possibly polluted, not necessarily rich in the bacteria needed to...

    once live "dead " rock

    If there happens to be any dried organic matter still in the rock it will only help with the initial cycle of the tank. Use the rock, and thank your friend for saving you a ton of $$$.

    Cloudy water

    There is good news, and bad news. The good news is that adding the 4 clowns together you are probably avoiding aggression between the clowns. The bad news is that they might gang-up on later additions to the system. The good news is that your ammonia is zero, the bad news is that it may rise...

    Roll Call

    I'm here now, but have been living in a monestary in Austria (true) for the past 2 weeks with poor Internet service. I'm back now.

    Which External Fiilter - Help Required Please.

    Wow, you have really done your homework! The only quibble I have is your use of an Eheim air pump. Marine systems don't use injected air, but rely on surface currents produced by powerheads and return pumps. Some have even predicted that a stream of air bubbles can produce problems with...

    That is right but they are also 65$ at my lfs. I can't spend that muchsince this is going to be a FOWLR system, save the $$ by eliminating the skimmer and get the fish.

    Aggressive Tang, help.

    It is a yellow tang. My father is starting up his 60 gallon tank. I thought about just putting him in there for a couple of days as a time out. A yellow tang, finding itself in a 60 gallon tank, will become more aggressive. This fish needs 6 linear feet if swimming space to be happy. Whenever...

    55gal fish selection after 3 crashes

    Butterflies can be difficult fish, especially in a new tank. The only success I have had with this type of fish is in a well established system where there is lots for the animal to graze on.

    Avoiding Snail Eggs

    Patience, grasshopper! If the snail eggs do hatch successfully (unlikely) and the fry grow to adult size (very unlikely) they will consume all of the available nutrient, and die off. Marine tanks have a way of balancing themselves out. Instead of worrying about the snails, worry about the...
