My tank was 30.2 c today, all looks ok, problem is that the coral grow too fast.

Not sure if you can drill a ar620 tank. Depends what type of glass it is.

No The maroon are too aggressive.

Bummer about the fish. White spot does seem to be a problem at the moment because of the hot temperatures. My tank got up to 29.7c yesterday. I would try to get something that is more white spot resistant like a 6 line wrasse. Blue tangs will generally get white spot with the fluctuating temperatures.

in nz do we have pure zeovit tanks.?? i am talking about tanks with pure sps corals, as this is what zeovit was meant to be for.

here is a thread about purigen. http://www.reefcentral.com/forums/showthread.php?s=&threadid=482205&perpage=25&pagenumber=1

Can Habib help??

Check out the blue face angel in the show tank, What a beauty

Thanks for that wasp. i did not know that . The reason i asked is that i was reading the Rowaphos advert and it said that some phostphate removers are iron based and aluminium based and it had zeolite in brackets, so i assume that zeolite has aluminum in it.

IS this not based on aluminium oxide. i thought aluminium is bad for your tank. is aluminium a big part of zeolite. can anyone confirm??

The Merck/deltec tst kit is a laboratory grade professional test kit which is obtainable from deltec but generally too expensive for the avearge hobbyist, the second recommended test kit is the one manufactured by Salifert,which is also sensitive at a low range but still makes it difficult to differentiate between the colours due to the poor optical clarity of the sample containers.

INFO What is it? - A refractometer provides quick measurements that indicate the exact amount of dissolved salts in water. This rugged laboratory quality hand held refractometer is incredibly accurate and exceptionally easy to use. The dual scale precisely and consistently tests +/- 1% from: specific gravity 1.000 / 0 ppt. to specific gravity 1.070 / 92 ppt. How does it work? - Simply place a few drops of aquarium water on the prism and place the prism cover on top. Hold it towards a light. Look through the adjustable eye piece. It reads in percent and specific gravity. Ideal for hypo salinity to brine applications. An absolute must for brackish water, marine fish and reef aquarium keepers. Light travels at different velocities in different mediums. A few drops of aquarium water are placed between two pieces of light transmitting material. Light goes through a high quality optical prism. The light beam bends at different rates with different density solutions. This is called refraction. Simply looking through the eye piece will give you exact salinity and specific gravity measurements. Why do you need it? - It is well known that inexpensive glass hydrometers are grossly inaccurate. It is generally agreed that the vast majority of plastic specific gravity testers do not yield consistent or accurate results. If a hydrometer is wrong by +/- .002 or more specific gravity units, calcium test results can be inaccurate +/- 75 ppm. to 100+ ppm! Meaningful testing for all ions related to successful marine fish and reef keeping is impossible. In order to evaluate the initial quality of marine salts and/or accurately test for calcium, magnesium, alkalinity and other important ions that may require periodic supplementation, it is essential to first determine the honest specific gravity or salinity of your marine aquarium water. Without first determining honest specific gravity or salinity adding the proper amount of supplements to obtain optimal levels is at best a guess. This refractometer takes the guess work and confusion out of testing specific gravity and salinity.

Yep it works great. however was changing a few things so did not have it going.

???????????????????

Before going to work today I thought I would do a quick top up. I turned on my DI and went and did in few other things. At work I get a call at 7pm to say that my lights aren’t on and that there is water coming out of my sump. I could not believe that I forgot to turn the DI off. and topped up about 1500L of fresh water. I rushed home and added 40Kg of salt into my skimmer over 1 hour to get the salinity up to 1.025-1.026 As lucky, as I can’t see any loses after adding freshwater for 12 hours, Salinity dropped to 1.010 And to top it off it off this was my 3rd time in the space of 2 months. You would think I learnt a lesson the first time.

MARK , On the subject of people advising you against salifert phosphate killer, You have not given 1 link that says it has damaged someone’s tank. I can’t even find any info on the Net. It is almost the same product as Rowaphos so how can the advice you are getting saying it has damaged tanks. It appears that you have deliberately and maliciously written untrue statements regarding the Salifert Phostphate killer without even providing any links or facts, Salifert worldwide has been informed and will be looking at the options available.

It takes more than zeovit to get a tank that good. Whilst zeovit does work ,Zeovit is a tool. It takes experiance and knowledge to get a top quality tank.

Do we have a scientific forum yet?

did you test this against a refractomer? Hydros have know to be way out

I dont have a problem with rowa or salifert phostphate remover. But of course i import both products. You have to beware who gives you information as this post shows. I have the largest collection of Acropora in the country and run over 2 Litres of PHostphate remover without any problems. here is a good quote i found on reefcentral

Well give us a few links of all the others that are having problems with the salifert phostphate remover?? Why would you want to use it as it is iron based and will destroy your tank . it is iron based as you will be aware. http://www.reefcentral.com/forums/showthread.php?s=&threadid=419143 Where is the link??

So what is rowaphos/aquamedic made of MARKKKKKKKKKKKKKKKKKKK??? where does randy say that it is the salifert phostphate remover that causes RTN? All iron based products are also going to lower kh. and could cause rtn. its not salifert phostphate killer is it. so how is salifert different to the other iron oxides?? all iron oxides can also cause rtn as they also lower kh http://www.advancedaquarist.com/issues/june2004/review.htm why stop there. carbon will also cause rtn and bleeching/ why direct it at salifert, what is your hidden agenda. Then you say that you will use rowaphos/aquamedic. which is the same thing, how are they going to not cause RTN.?? and quote by Randy Holmes Farley Salifert is not designed to be fluidised, it even says it on the packet. NODLE. Sorry to spoil your post.

what total rubbish, what is wrong with it?? As for Rowaphos, it is even more expensive, however as a option it will be available again in a few weeks Rowa can be fluidised, but salifert cant. Both are iron based, salifert is dry and rowaphos is wet.

Day 10 update on MM. Tank started to show signs of diatoms all over the glass and sump. algae growing well , however have had some die off. Corals looking good and acros are open all the time. will post updated pics in a few weeks.

ONCE AGAIN SPARE US THE DRIBBLE.
