08-05-2006 20:03 by rob r	sunlight yes
08-05-2006 20:09 by Ed	Nutrients.
08-05-2006 20:10 by george	phosphates and nitrates!!
08-05-2006 20:16 by milo	and extra oxygen in the water.
08-05-2006 20:32 by tommy	so you are sayin to much oxygen , and light
08-05-2006 20:33 by billysfc	It's completely natural to have algae in a marine tank. Even if you can't see it, it's still there just waiting to take hold again. Keep a good clean up crew and if it doesn't reach plague proportions, don't worry about it.
08-05-2006 20:34 by Ray	Algae are simple plants that will be present in every healthy tank,they use nitrates, phosphates and carbon dioxide to synthesize food and produce oxygen as a waste product,they will only absorb o2 at night in small quantities and do no harm to any set up other than smothering higher plants in a freshwater aquarium.
08-05-2006 21:11 by tommy	yes but it is all green on my white rock and looks rly bad
08-05-2006 21:12 by tommy	so there fore i have turned out the light and stopped the oxygen which i have had on for about 3 weeks and going to leave it for 2 days and see any diffrence
08-05-2006 21:14 by george	and use a nitrate and phosphane reducer....eg green x!!!
08-05-2006 21:22 by tommy	is that a prodcut .. were can i get it
08-05-2006 22:52 by Ed	Excess nutrients will cause algal blooms and start sending your parameters all over the place as ray said it is normal its just unsightly to us humans .Plenty of live rock as much as you can afford,do away with the externals,use a sump if you can ,cut back on feedings to 2 times a week and some decent circulation pumps ,dont forget the skimmer thats debatable there is a big for and against depends on what you keep .That simple it should work perfect and some patience.
08-05-2006 23:02 by billysfc	Is this a new tank, 'cos as you get a corraline algae ( purple or pink) growth on the rocks, the green algae doesn't seem to stick to it anyway. If it's new it's just something you have to put up with for the time being until you get some good corraline algae growth going on. If you don't have any live rock you need to get some, or buy an invert with a good growth of corraline on the rock it comes with. Try syphoning the algae off the rock with a bit of air line when you do a water change. Have you got a marine keeping friend, can you borrow a good if small piece of rock off him for a month or so ??
08-05-2006 23:29 by tommy	my tank is full of live rock its the trigon 350 and has been running for over a year now .. i fink i need to A. cut down on food B ...let it do it its self i mean i have just added 2 large lumps of rock which are starting to go purple so maybe the green is there due to that
10-05-2006 08:57 by Alan	How many grazers have you got? You should have at least 1 hermit for every 2 gallons of water as well as snails at a similar ratio the use of snails with hermits needs to be done with care though as some hermits will eat snails I go vfor large turbos to big for the hermits to bother. The snails manage the glass the hermits do the rest.
30-06-2006 08:28 by blondie 1	hello! I desperately need advise on my tropical fish aquarium. I got suspended green algae in the water, ive tried water changes and cleaning the filters, the light has been left on alot (thanks to my wonderful children!!) so the algae has gone mad. Im trying a 7 day treatment from my local aquatic shop, ive been treating them now for 4 days (Carbon filters removed) and it looks to be getting worse not better! Should i carry on the treatment or take out the fish and strat again?? Please help me!! I have had the tank for 6 years now and never encountered this before?
30-06-2006 09:26 by Alan	Water changes are the key and the removal of detritus the algae will do absolutely no harm to the fish. Do you have a gravel substrate if so when doing water changes use a gravel cleaner and gradually work your way through all of the gravel so it is spotless this will reduce the nutrients in the tank greatly. Every week carry out a 20% water change siphoning through the gravel as I described also make sure the filters are as clean as possible only clean them though in waste tank water never under the tap. do this as necessary but while tackling this problem I would say every week. In addition use a good tap water conditioner such as stress coat. This will neutralise chlorines heavy metals and chloramines. If you keep this up for a month the green water should pass also as far as lighting on the tank goes keep to a routine photo period with my tanks they get switched on in the morning at about 630am and then off at night at 10 or 11pm so about 16 hours I never have an algae problem because I keep the nutrient level low that is the key to controlling algae in a tank. I think you may be at the beginning of something called old tank syndrome it needs to be addressed fairly swiftly to avoid the nasty side of old tank syndrome where the ph crashes and filter bacteria peg it and ammonia goes through the roof. I would abandon the use of the green away you are treating the symptoms not providing a cure.
30-06-2006 21:15 by blondie 1	Alan, thanks for your help I will start water changes straight away! I have a gravel cleaner, and always clean my filters in tank water. How long do you think it will take before i will start to see an improvement? I can hardly see my fish and want to get it sorted as soon as possible. Will it be ok to stop half way through the treatment? I have bog wood for the display,if I remove that whilst doing the water change and gravel clean will it help?? Will it also help to keep the tank covered up? blondie! PS Tank light now on timer and cupboard locked!! x
05-07-2006 09:07 by Alan	It should be sorted within a month or so. Stop using the green away now and immediately carry out a large water change.
