Re: River reef tank help #1
the previous answer has delivered you very sound answers. 94 liters is too small for the usual angelfishes. The only species you could host are C.fisheri (6 cm for male in te wild) but it means only a couple of them.
as regards the skimmer : the technical explanation is that at the surface of the air bubble in seawater there is an electrical charge that attracts all kind of proteinic compounds, the resulting foam is thus a concentration of decaying products of various origins.
This is one thing. Another one is that the skimmer is the best and most efficient place to mix air with water thus providing an excellent oxygen rate for the animals, the consequence is also the providing of a good redox rate.
For me, skimmers are a thing to have in one's tank, at all costs.

Re: Orca TL450 or 550????? #2
This is perfectly true but when I'm dealing with someone starting I always tend to be overcautious about the amount of time he/she is ready to put into the tank keeping.
I perfectly agree with you bred occelaris tend to be smaller, as all clowns raized. They sometimes tend also to havefunny behaviors: I have a couple of A.percula, the male refuses to swim deeper than a few inches ( no swim or bladder problem though).
It really is all a question of time and money investissment.
for the crew : snails are great of course, take hermit crabs of different species : best are the small tricolor, those with red legs, also a species with pink legs and orange claws (or the opposite ), and the pyjama. The green legs or the elegans grow to large and behave as bulldozers in the tank.
also avoid the temptation of the small urchin as they may not be that reef safe with soft corals and zoanthids.
for the shrimps : thor amboinensis is great in groups depending on the fishes living with them, or Lysmata sp.
the red debellius is discreet but beautiful whereas the orange/white amboinensis is tough with corals sometimes but always to be seen. avoid the camel shrimps absolutely if you fall for zoanthids. Periclimenes sp. are very beautiful transparent shrimps, rather living in symbiosis with other animals : anemones, urchins, or stars.some are cleaners as the 2 species of lysmata are.
the first crew members are to be added when the nitrite peak has disappeared, just before or at the same time of the first algal boom.

Re: Orca TL450 or 550????? #3
hello
I do agree with you Pouch that occellaris do need a small territory in fact, the only conterpart is small tank = small depolluting system ( i.e. small skimmer) and that is the bad point.
No need to fix your rocks with anything and anyway do not. Place your rocks in a stable arrangement without sand, when the whole doesn't move anyore, you'll be able to add sand afterwards.

Re: Orca TL450 or 550????? #4
occelaris are bit too big for this size, firefishes are just great but beware of their jumps outside the tank. they are just wonderfully and at the same time delicately coloured be they the fire or the purple one.
in this case, a couple of very small fishes such as trimma sp. or eviota sp. would be great. I know that in England you are lucky enough to find Dorhyramphus excisus regularly. I have a friend here in Paris having them in a small 36 liter tank and keeping them with success, feeding them with mysis. I have other friends having another one too. It is a very beautiful and original species.
for a more moving tank, you could get a couple of the blenny Ecsenius sigmatura instead. You'll get plenty of choice and we'll help you.
but first and foremost pass all the first steps of maturation.

Re: Orca TL450 or 550????? #5
hello
it is always the debate between choosing a so called plug&play and to make one's own choice to equip one's tank.

Fortunately here in France, those plug&play tanks are not so vivid apart from Red sea.
The problems are always the same : lights are not sufficient ( here 36 w for some 58 liters) at all in your case. I do not know the efficiency of the skimmer. If case you had ceramics inside, do not put them in, there are of no use in reef tanks and more the source for nitrates than anything else.
pumps also are often too scarce so you often have to add at least one.

58 liters is a perfect size for a new start, smal enough to fit in the home but large enough to host a few things.
at the same time, 5 liters change of water a week is not unmanageable at all. I am sure this shall give you a maximum of pleasure and we will give plenty of help on the site.

Re: TMC 120 skimer #6
"why don't they put that in the manual? "

Because Ryan, there is a very poor link, if any, between our hobby and the scientific research field unfortunately.
With the knowledge on coral biology, because it's what it is about in a reef tank, people would be able to conduct a sound way of keeping corals, to choose from the species viable in our tanks on the long run and moreover to make the right choice among all the more magical unlabelled potions coming from the ornamental aquarium industry, and the right choice of tank running habits.
We, the elders in the practise, have also a certain reponsability in that state of things : we have turned tricks into unexplainable rules, and some of us have not turned into these scientific readings.....Others have and are wonderfull ambassadors of the practise.

Re: TMC 120 skimer #7
there are various objectives when you're using a skimmer

the first one and most obvious is the removal of decaying matters from the water. There comes a problem when you distribute plancton as food for corals. In thsi very case, you should stop for a while your skimmer ( a while is 1/2 hours). Then when on again, the remaining plancton is exported with the foam.

A less obvious one is the oxygenation of the water. Of course, the water movement provides with some oxygen through the gas exchange abilities of salted water but it has other impacts. The injection of O2 into the water raises the Ph ( good for the fish) but also a high PH enables a more efficient calcification i.e. coral growth for corals. At the same time, it raises or keeps the redox high wich acts as a kind of buffer for the capacities of reduction and oxydation of decaying matters, in case some should appear. A high redox is a most welcome value - sound tanks have between a 300-400 microvolt value).
And whatever people will say, skimmers remain one of the most efficient place for mixing air and water.

So yes you should always keep your skimmer on except during the distribution of planctons to corals

Re: Bubble alge #8
yes they should. be careful to pick a reaaly small crab, it can take its time to feed on the bubbles but it usually comes to it one day or another.
The esmerald crab may lead to problem with corals instead, particularly softies such as Sarcophyton sp. as the crab may feed on the mucus and thus troubles the polyps.
really bigger crabs may be a danger sometimes to really small, slow fishes. But on regular basis, always keep an eye on any crab and feed it if necessary as they may become used to it.
I have a rather "big" red Trapezia sp. in a Stylophora sp., and I have taught the crab to come outside the "bush" and get its food whenever I am feeding the rest of the lot.

Re: algea and fish advise #9
h?h?

whether it can be kind of consolation to you, I am faced here in France with exactly the same problem. Being the webmaster of a French site, I sometimes have to deal with idiotice advice or sales newbies report us.

the only way to prevent you from that is to speak with people used to the practise of marine/nano practise, if there's any difference between the two, which I really question.

Re: Bubble alge #10
hello
it is a rather difficult task, the emerald crab ( Mythrax sculptus or sp.) readily eats it but you have to keep an eye on the bigger specimens as they remain opportunistic.
the one thing not to do is to pierce the bubbles otherwise the spores will spread in the tank more again
