chimera Posted July 13, 2004 Author Report Share Posted July 13, 2004 I scraped off as much cyano from the rocks last night then mixed up enough RODI/ASW for a 20% water change. I let it aerate last night then changed water this morning (I lost about 5 litres on the floor when the tube coming from the eheim pump popped out the sump and sprayed around the room like a 14 year old boy with his first porno) I also tested the water coming out the nitratereductor (bacteria have been building up for a few weeks now) and Nitrate levels are about 1ppm compared to the main tank at 20ppm so that should help significantly too (relating to overall quality of water chemistry that is, not the cyano). Anyways, I will monitor it over the next few days and let you know the results. Quote Link to comment Share on other sites More sharing options...
Interfecus Posted July 15, 2004 Report Share Posted July 15, 2004 Interesting cyanobacteria facts (from my plant bio course): 1. They were the original photosynthesisers and by altering the early atmosphere made the use of oxygen in respiration (breaking down food, not breathing). This allowed complex life to evolve. Without this change, we wouldn't be exterminating them from aquaria today. A bit ironic really. 2. Approximately 3.5 billion years ago, they used to form huge mounds called stromatolites up to 30 metres high in shallow seas. Compressed by the weight of the tower above, the bacteria on the bottom were compressed until they formed fossils. 3. They still contribute about 30% of the world's oxygen production, bubbling up to the surface of the sea. P.S. Mass slaughter of these helpless organisms will incur the wrath of the New Zealand Bacterial Rights Group (NZBRG). Bet you're afraid now .

Ira Posted July 15, 2004 Report Share Posted July 15, 2004 30 meter tall piles of algae...That'll put yours in perspective, Chimera, what're you complaining about? Quote Link to comment Share on other sites More sharing options...
chimera Posted July 15, 2004 Author Report Share Posted July 15, 2004 best i get a 40 metre tank then and try and beat the record Quote Link to comment Share on other sites More sharing options...
chimera Posted July 17, 2004 Author Report Share Posted July 17, 2004 Since posting last Tuesday, nitrates have dropped from 20ppm down to about 10ppm (colour appears to be little over 10, perhaps about 12-13) and phosphates have dropped from 0.20 to 0. Since then, I have done a 20% water change with ASW. The reduction in nitrates has also been helped by the nitratereductor working hard out (1 drop per second works out to something around 20 litres per day or 100 litres since last Tuesday) I am mixing up a batch of RODI water at the moment for another 20% ASW water change tomorrow night. I have physically scraped off as much cyano from the rocks as possible. It is still coming back but not nearly as quickly as it was a week ago. I have the MH's now so will look at designing a hood for them to hang in today and see if this helps remove the cyano. Will have to design it (according to jetskitsteve) so the lights sit higher up for a few weeks then bring it down once the coral's have adjusted. I might put in 7.8K lights in (some spares that came with it) then change to 10K in a months time. Hopefully the better lighting will help reduce the amount of cyano too.

jetskisteve Posted July 18, 2004 Report Share Posted July 18, 2004 7.8??? you sure? prob 6500k if so don't bother these are great for growing algea just do as planned with the 10k. Quote Link to comment Share on other sites More sharing options...
chimera Posted July 18, 2004 Author Report Share Posted July 18, 2004 something around that ok, will go straight to the 10k's..! Quote Link to comment Share on other sites More sharing options...
Pies Posted July 18, 2004 Report Share Posted July 18, 2004 Lots of people use 6500k for coral tanks. Some people belive that 6500k bulbs are better for growth. Eric Bourneman uses 6500k + 20K on his stoney tanks. Quote Link to comment Share on other sites More sharing options...

chimera Posted July 24, 2004 Author Report Share Posted July 24, 2004 I think the theory of those getting cyano when using NSW vs those who have not had it using ASW maybe true (or at least partially) IMO, using NSW means you are more likely to get cyano whereas using ASW you are less likely to get cyano. I say this from those who have posted previously regarding cyano and the type of SW they use. I also base this on having my tank and using ASW for several months, then switching to NSW and getting cyano within a month. Coincidence? Perhaps.

JackJackJack Posted July 24, 2004 Report Share Posted July 24, 2004 sounds like a decent theory to me, and all the examples i can think of support it. although they have cyano problems in the US and nearly all of them use ASW? im guessing the cyano comes in the water? or does the water promote its growth? only way to find out i guess is find someone who went from NSW to ASW Quote Link to comment Share on other sites More sharing options...
jetskisteve Posted July 24, 2004 Report Share Posted July 24, 2004 Hey Reef donate me some salt & I'll test that theory 4U Quote Link to comment Share on other sites More sharing options...
reef Posted July 24, 2004 Report Share Posted July 24, 2004 No need to test the theory. I already said that all people I know of have cyno and they all use NSW. Nsw might have some type of bacteria in it or maybe it is the extra nutrients from run off. Mind you, when I was using sea water I did not get cyno. Might be the dirty water at Takapuna beach.

chimera Posted July 24, 2004 Author Report Share Posted July 24, 2004 Well Im going back to ASW for "a little while" (reason is, I need about 600 litres of water when I get my new tank setup and I aint gonna wait for a RODI unit to produce that much water and spend $100+ on salt!!!) Until then though, I'll use ASW. I want to see if it clears up (which wont exactly say whether it is a definate or not) but it might suggest the cyano is less likely to appear with ASW than with NSW. First time going back to ASW was 17th July (change about two weeks prior was NSW) I have done another 20% water change tonight with ASW and will continue at 20% each week until the new tank goes in (hopefully within 3 weeks) Cant wait for the new tank, my fish will be so much happier with that much more water available to them!

Nicks Posted July 26, 2004 Report Share Posted July 26, 2004 Mind you, when I was using sea water I did not get cyno. Once again Reefs memory is slipping. I can remember a long time ago that reef had patches of Cyano in His tank!!!! FYI. Cyano is present in all tanks, it is just out competed by other algae/bacteria so is not visable. It does not need an increase in nutients in the water (although it helps) as it can fix nitogen from water, substrate, rocks ect to form its own Nitrates. Hence it can be present in very clean tanks. I beleive that is is very simplistic to say NSW=Cyano. I actually think that people who say that are Stupid and don't under stand basic reef chemistry I do not have an out break of Cyano as reefs says. I have had over the many years in keeping marines using both NSW and Mixes. The last out break vanished when I moved tanks. Anyway I am a believer and will stick to NSW Quote Link to comment Share on other sites More sharing options...
chimera Posted July 26, 2004 Author Report Share Posted July 26, 2004 It was never said that NSW=cyano. It was said that it is possible that NSW=more likely to breed cyano than ASW. BTW, I've found the best way of getting rid of cyano from your rocks is using a tooth brush Quote Link to comment Share on other sites More sharing options...
Interfecus Posted July 26, 2004 Report Share Posted July 26, 2004 Note: Not all cyanobacteria can fix nitrogen, it depends on the species. Some will only flourish if dissolved organic nitrogen (ammonia, nitrates etc) is present. Quote Link to comment Share on other sites More sharing options...
reef Posted July 31, 2004 Report Share Posted July 31, 2004 I believe that is is very simplistic to say NSW=Cyano. I actually think that people who say that are Stupid and don't under stand basic reef chemistry NSW =CYNO. The main reason for this is due to the high level of dissolved organics that are usually present in most seawater collected because of pollution. Using NSW from a clean source will most likely not cause cyno. Quote Link to comment Share on other sites More sharing options...
jetskisteve Posted August 1, 2004 Report Share Posted August 1, 2004 How do you explain yor cyno at the moment then Alois Quote Link to comment Share on other sites More sharing options...
reef Posted August 1, 2004 Report Share Posted August 1, 2004 Some minor specks of cyno in my tank is due to the tank load and overfeeding brine shrimp. I am surprised you would even notice it, You sure you did not see coralline algae.?? Mine is nothing like yours which is out of control, i can still have a substrate in my tank.
