Control

Unlees you see one eating a live worm i wouldn't worry about it because they're most likely eating the vegetation. and are just another live food that you seem to be breading. You might want to keep an I on any plants in the surrounding area but I can't see why they would leave a meal like that. Aaron.

You don't have to put it above your tank Aaron

It is likely to be a light issue. I'm not sure how much you know so forgive me for explaining to much. When a Zooxanthellae cells which are algae that live in the Anemone are exposed to light that they are not use to they curl up, this in turn causes the animal host to do the same. It should settle in a couple of days. What sort of lighting did the shop have. Assuming that your tank is running well and that the foot hasn't been damaged on the Anemone it shouldn't be a problem. You may have to just wait and see. If it does'nt you could have problem with your water. Most Anemonies live at the top of the reef and can even be left high and dry for many hours during the day yet they survive with easebecause of a mucous that they excrete which has UV blocking propeties. Where they live the water has the highest level of saturated oxygen. they also have very turbulent water at times, this does not mean you should aim a pump directly at it. Aaron

250 isan't much higher than our on shorelines have and is nowhere near the level of a reef. The most likely reason for your tank not suffer with a low Redox would be that your skimmer was good enough to keep any resulting side affects under control. This is hardly an ideal solusion. I am still trying to find them. Please bear with me on that. After we moved I had to put them all in one of the test tanks in the garage. The front glass broke and I lost everything. The tanks ran for ten years without crashing once and I was deliberately over feeding them at times to see what would happen. My 6' tank is running on very basic gear at the moment and only has the following in it; 2 x Perc Clown I x Manderin 1 x Blue Tang 1 x 6 line wrasse 1 x Hammer head Coral 3 x leather 2 x Mushroom 1 x Anemony I have no intention of getting anymore until I put the rest of the system back together. There isan't much point in putting a Piture up as there I isn't much to look at. It's a mess If it wasn't for the ozone helping thr stupid little skimmer that is on it everything would be dead. Reef. Just out of curiosity what is the longest period of time that your tank has run without crashing. And did you ever come to an accurate reason as to why it happened. Aaron.

Why have you bought ozone into this. Its not an issue and no one has suggested its use. The issue i made was Redox Potiental. Many people have made similler arguments as to the use of protien skimmers but we still use them. I can easily find systems on the net that use, or dont use it. And have, and or show the same, and differant results. That is very misleading. Not all of them have single point calibration. And the fact is that half of the PH metres have single point calibration. Alot of them have 2 point calibration just like the better PH metres. The AquaController2 has 2 point calibration, Never bye one with single point calibrtion. The ORP is calibrated in Quinhydrone saturated solutions of PH4 for the low point and PH7 for the high. This is very accurate. To high (above 450mv) is not a good idea. To low (below 280mv) will cause the system to slowly collapse. If someone is adding supplements or have "dechlorinating or ammonia removing compounds" in there system in high enough levels to affect a Redox reading then thier tank has some serious problems. Only PH and Temperature will do that. This is not a problem, The aquaController2 has a program in it to cater for this in it's readings. This feature can be turn on and off. Most half decent controllers have this feature. Yes it is. But; Usaully the first sign of a collapse in a filter systems and/or tanks that is not related to thing that can be supplement is a sudden drop in Redox Potential, then the oxygen level. This will always happen before you see any physical signs. After That the animals will show signs follwed by the inviroment. I would rather know about any problems in that order, and have a chance to do something about it before it affects the animals. I have done so for ten years and have no intention to change. And if you do use ozone as I always have the Redox must be controlled. No they don't. A reactor uses alot of pressure to oxidize the water. a skimmer uses pressure to mix them which degasses at the same time and is not as affective at oxidation after the skimmer if they were you wouldn't have to put baffles in your sump because the oxygen would have oxydized with the water. Reefs have well over 70% oxidation. the fact that your Redox reading is good does't mean that you have a high saturated oxygen level. 250 is starting to get a bit low. A stable tank would not go that low without a cause. Who said and where is it written that you need ozone to to get a Redox of 400. That all depend on you and how you look after it. You can get checking fluids to make sure it is calibrated properly. The point is that Redox should not make sudden drops and if it does you will get a sudden drop in saturated oxygen as well. This will inturn affect the systems stability.That is all that i was saying. Aaron.

Time will tell. Aaron.

There are plenty of oxygen kits out there. If you get one make sure it can measure up to 100% in salt water. Most of them are for ponds and swimming pools. I just use the ORP on my AquaController to tell me if I have a problem. If it drops the water will lose that lovely clear look. There are many ways to increase the ORP in your tank, and many things that can cause a drop. If the oxygen drops an increase in organics in the water is most likely but you wont notice an increase in skimming because the lower oxygen level will lower the performance of the skimmer no mater how good it is. Are you using an oxygen reactor to increase the oxygen and help the skimming. There could be something wrong with the way you are running it. This is just one possability. Aaron.

I've never seen that before. Do they cause interferance with electronic probes. Aaron.

How big was it. Aaron.

If it is not algae related, the Redox Potiential could be low. Do you have an oxygin test kit or the means to measure Redox Potiential. Is your skimmer pulling more or less out than normal. Aaron.

Malu Anemone. They can also have purple or blue tips. No need to treat them any differantly than others Strong light is a must, you can feed them peices of muscle, but you don't reallyneed to. do not put it into it's mouth put it in the tentacle's You should of got them to hold it for you until you got a metal halide. Have you had Anemonie's before. Aaron.

Pies It should be stamped on the bottle. The reason I asked was that they are filled by weight not volume , it just seemed strange to hear litre's not weight. Pies and Wasp All the co2 tanks I have seen are alloy not steel. Acid and steel are not a good mix. They must be oil free. Wasp Get the biggest you can afford. It wiil pay for itself in the long run. This is one of those things that you will regret if you don't do it right the firt time. Another thing you need to consider, if you don't have one already is a precision needle valve Aaron.

I own mine too. It just had it's 5 yearly presure test. Pies What weight do they fill it to. Aaron.

I made my own pump for this purpose. They're not cheap considering how simple they are Do a search here in pumps. http://www.directindustry.com/ I made mine from acrylic tube and sheet with silicon rubber for the diophram's and one way valve's. They work in the same way that a diophram air pump works, however the diophrams and valve are alot bigger. This enables living things to pass through without being damaged. The diophrams are driven by a DC moter with a shaft going to them pulling them backwards and forwards. While one is being pushed open the other is pushed to close. One great thing about them is that a big one running slowly creates a pulse of water instead of a constant flow. Aaron.

I think we might need a picture for this one. Aaron.

Pies I've never seen that before can you put up a pic of it.

Handbook of fish diseases. Dynamic Aquaria. Two or three others somewhere. Aaron

Baffles are a must. You don't need a large flow. Don't use pumps with impellers, use diaphram pumps for the refugium.

Refugiums should not go through the filter system. It defeats the purpose. It should be a closed loop with the tank. You can put it anywhere you like. On top is best because of the type of pump. If you have a refugium you must use diaphram pumps. Aaron.

Pies I think you mean 5kg not 5L. Pies is right. Its alot cheaper to run a big tank. Compare the prices of your options including the running cost first, you may regret it in the long term. I've got a 4.5kg and regret not getting a 10kg. Size was my issue there. Aaron.

Reef is right, it will probably come back bigger and soft corals like good water movement. Only start to worry if it shrinks or goes shinny. Aaron.

This needs to be put in a "sticky" or "usefull links". Why do we not have any in "saltwater" Aaron

I Had a blue check goby. I spent more time watching him building and rebuilding his cave than I watched the rest of the tank. I must get another one. A word of caution; Make sure your rocks are stable as they can undermine them. Aaron

Cracker That tank looks fantastic. I think I'll do one that size. Aaron

It sounds to me, that he knows where his food comes from. If you feed your tank try feeding it.
