there must be something wrong with my skimmer a well, Its been producing so much micro bubbles and all the foam is building up in my collection cup and my tank water looks so clean. Can anyone help me and Ira with our skimmer problems?

they sure work. here is some info from a german page If you feed much and you have many fish in your aquarium nitrate will accumulate with the time. If you cannot lower the concentration with water change, trickling filter or living stones you need a nitrate eliminating filter system. If nitrate is more than 20 ppm in the water negative growth of green or blue green algae will occur. Some kinds of fish do not tolerate high amounts of nitrate, too. Autotrophic de-nitrification has some advantages compared to systems that work with heterotrophic bacteria. With the ADN filter you do not need an organic compound. Theses substances like alcohol, organic acids, sugar, PHB = poly-beta- hydroxy-butyric acid ("Deniballs") etc. may pollute the water. Additional a very strong bacteria growth will occur. These bacteria are polluting the water, too. The handling of heterotrophic filter systems is very complicated or you need an expensive controller (look at Roto-Bioreactor). The small disadvantage is the long time to start the filter and if you have very rough changings in the nitrate concentrations, the filter will need a little more time to adapt to the new concentration. But in an aquaristic system you will not have difficulties. Like other autotrophic bacteria - nitrifying bacteria - they will work in a coral reef tank without problems. The advantages are much bigger than the disadvantages: long life time of the filter substrate low biomass growing - therefore low bacteria pollution of the aquarium water high flow rates no additional organic compounds are necessary easy de aeration intensive mixing wihin the filter with a good pump - therefore high efficiency if you wish with Redox control (ORP) for filter sump or for stand allone

it will take about 3-4 days before it will work as it will need to produce a slim coat inside the skimmer. also the air going into the skimmer needs to be reduce for a week and then fully opened.

the best way is to follow the instructions. i have doubled the dose with no problems. the plan would be to do the following. turn off main pump syphon as many flatworms as possable add salifert exit as per instruction turn power heads on full wait 30 mins add carbon to main tank and wait 5 mins turn on main pump. thants it repeat in 1 week

well look what arrived last nigh. 4 great looking idols. after 6 hrs they started to pick on rocks, so lets hope they start to feed

Mine seems to grow best in medium light,

no problems, keepimg them alive, i ordered four. got a tank full of algae

Just ordered my dream fish. moorish idol.should arrive next week fantastic fish,

IRA i must agree with pies. 28c is very hot for a cold water tank. if you are going to keep new zealand marines then you will need to get the temp down to 17c, for tropicals it is about 25c, so i think you will need a chiller. Its very hard to keep the temp down on a small tank without a chiller. i quess you are using a cheap hydrometer as well, so the salinity could be anything as most hydrometers are calibrated at 25C As they say, YOU CANT DO MARINES ON A SMALL BUDGET AS IT GET VERY EXPENSIVE IN THE END, AND IF YOU DONT LISTEN TO ADVICE ,YOU WILL FAIL.

IRA, hows your triple fin. Has it survived the ammonia cycle.

pies..hows this for a acropora

Hi warren Power cost is about $400 per month. But that includes other tanks of about 2000 litres. I do have a problem as the power turns off when I turn the microwave on. I will have to run a ext cable from another area to relieve some of the load. Don’t run a chiller yet. It is fairly cool in the room were the tank is located. Tank gets up to 29c some times but hangs about 28c in summer and 26c in the winter. Nice clam Steve must be the diesel in the Takapuna seawater. Get some anemone pics up......

come on pies and jetski, lets get those pics up.

i thought it would be a good idea if we posted some tank pics to show some of the newbies how a reef tank should look like. here is some pics of my tank taken today Full View

works for me

fluoros are ok for mushrooms some leathers, why not try t5s much brighter. never seen a decent tanks with fluoros.

IRA, if you are going to keep tropical marine then you will have to cycle the tank with tropical temperatures, if you are keep local marines then you will need a chiller. as temp needs to be about 17c. You can’t just heat the tank up one day and then change it to a tropical marine tank as you will kill all the bacteria and all the marine life.
