fair points Chim, but 3 months isn't a long time in reefing.

hell of a lot of light Chimera. 3 X 400 w on a tank your size - wow. Hasn't reef changed back down from 400w to 250w recently?? Alot of people have good colour, I am getting there as well, with alot less lighting. In fact reading some threads on reef central, there are colourful tanks using just T5s, and more colourful tanks with MH running for just 3 or 4 hrs. just a thought, ever thought of letting your tank settle on one change before rushing off and changing things again. Maybe your acros never get a chance to adjust to any one parameter.

no power cuts at home. Factory lost power so sent everyone home, and followed shortly after

:roll:

Cookie, I thought the devils hand was a leather type coral???

fair enough.

no need to go any further reef, your an importer, you import certain products, there are other importers that import other products. JMD, who my post was directed at answered in a good way, dismissed it, so give it up. I don't want to be banned, so................

same reason the mods are keeping an eye on some threads maybe Alois

Same Sharkey, sps growing and colouring well, mushrooms hopeless.

"abstraction of the controlable variables" I don't know about others, but to keep mine running well, I make sure the bubbles a bubbling 1-2 per second, I make sure the outlet is dripping, starting at a fast 4/5 per second and don't bother resetting it until in almost stops, which takes a week or so. Take 2 minutes to open the tap and reset the water drip. The main reason the calcium drops slowly is the 60 litre water changes I do at least once a week with red sea salt. Its low in calcium and slowly brings the system down over a few months. Can't get much easier than that.

One (2 including you, layton), mans opinion. Note that he says that he was a trained chemistry technican, and you are some what of a academic as well. I don't think it would be an easy or cheap system to run, compared with someones like Steve Weasts. (change the media every so often, no other additives)

from Oregonreef.com "The calcium replacement needs are handled by the Deltec reactor, which pretty much just leaves cleaning and feeding."

Nice TM, wonder if that will ship to Auckland :lol:

Yes, a good discussion. Just be aware of the reasons some people promote some products.

They rate the calcium reactors to tank size. The bigger the tank, the more stock, therefore more calcium and alk demand. makes no sense,IMO, to say they are only bigger to make the media last longer.

undertsand that but what about this question: "Are you telling me Reef that if i put an emormous deltec reactor on my tank, it wouldn't keep up with my Calcium demands.???" is not, then can cross that off my wish list.

Deltec make 5 different sizes of calcium reactors for tanks that range from to 120g to 1300g. Everyone is bigger than the last, holds more media. Presumably as they get bigger the hold more water, can input more CO2 to drive the PH down and allow more Ca to dissolve into the water. Are you telling me Reef that if i put an emormous deltec reactor on my tank, it wouldn't keep up with my Calcium demands.??? Re read my posts, i said bigger/better.

reactors vary to suit your tank size and calcium usage. A bigger/better reactor would maintain my calcium levels. The reactor I have is rated to 1000l, a bit under what I have. This means a smalltop up every few months, so i'm happy with that and can't justify a bigger calcium reactor.

TM, a calcium reactor will not raise your levels of calcium just maintain, Yes my calcium slowly drops. When my acros weren't growing much it didn't but now there reasonable growth, it drops maybe 10-20ppm a month. Alkalinity stays between 9-10 and Mg drops maybe 10ppm a month (another lot of Mg dolomite in the reactor would keep it steady i'm sure). My Reactor does require me to adjust the drip rate every few days, tends to clog the tube a bit, but would not be without it now.

same thing with me CE. The population grew, collapsed and now there are just patches of them. Most are in the refugium, where the flow is lower High nutrients Reef, maybe, but I don't have a high nutrient tank now and still small patches of flatworms.

Pretty much what I've read as well TM. Read up, check Wetwebmedia, reef central etc before getting carried away.

are you sure Suphew?? All suddenly die and poison your tank??. Never read that anywhere. Alot of very good reef tanks overseas just live with them.

layton, Can't agree with you. I'm no expert on tuning reactors but had no issues since the day I started it. It is one of the things I put down as having made the biggest positive change to my tank. Good steady calaium and alkalinity levels.

calcium reactor looks after it mostly. Mg chips in reactor as well. Very small amounts of Calcium chloride and Magnesium chloride every few months. Reactor takes care of Kh.

and be really careful with the flatworm exit, lots of horror stories out there about using it against these flatworms. there a probably dozens more flatworms for every one you see, they are toxic and can quickly kill your whole tank. take that step very carefully.
