No need for additives???

Someone who own beutiful and mature SPS reef told me that he add no additives at all...
All he do is refreshing 10% of his SW water per week (or at least 30% per month). Nothing more.

Any comments please?
 
With a CA reactor it should not be a problem imo. Really no reason to add anything if your CA,ALK,Mag are good.
 
I think what it is, is some people have a good understanding of their system and it is successfull for them. If you look at World Wide Corals 300gal display is is simply amazing, and they don't use additives. BUT they also siphon detrius daily, change water whenever needed(sometimes 2-3 times a week), etc.

Then you look at people who run a full zeo system that has crazy colors. Then you see someone who just adds the basics and it looks great. I think whatever system makes the most sense to you go with it, just be dedicated
 
I can't imagine a full SPS reef without some sort of additive though. Its chemistry and the corals need certain elements present in the water column to grow and survive and in our tiny closed systems there is no other option than to add these supplements. He very well may be getting away with weekly 10% changes, but he would still have better luck if he would employ some sort of dosing regiment to help slow down the drastic parameter swing.
 
I do the very same thing tanks only a year old tho...

No need to does ca or alk because I dont have enough coral to make it drop much and 15% weekly keeps the prems perfect.

sps and lps
 
i do the same just change water every week for my 90gallons that work. i have mix reef and alot of SPS. everything look great.
 
my alk, calcium, mag dips during the week and i do 10% water changers every week on my full blown sps tank.
Is it the salt you guys use? How do you do it?
 
for something that is consumed, like alk, ca, mg, unless you are doing 100% water change, it is physically impossible to replenish by water change only. if you keep doing 10% water change only, eventually your CA will only be at about 40ppm after a 10% water change.
 
I remember seeing a Totm recently of the Greenwich Aquarium tank.
An amazing system maintained by large weekly water changes!.

Anybody got the link?. I can't find it now...... :(

WI reefer55 and Nam Nguyen,
Could you please post some photos of your reef tanks?

here is some picture of my tanks.

that is some picture i have for the tanks right now. sorry for the terrible picture.
thanks alot

Nice tank Nam.

I think zero dosing is possible as the newly mixed water should already contain everything needed... the harder question is finding the combination of how much water change/tank volume and consumption that work for each tank.

I am still dosing as I found it is easier for me to keep up/control the tank, while still doing 10 gal/week on my 150 gal.
 
Very nice tank Nam. You must dose something to keep growth and colors up. I agree with what was said that if you do just water changes then your Ca will slowly continue to drop. Water changes alone will keep up for at least a while. I use high quality reef salt with weekly water changes I feel that helps replenish trace elements. I dont rely on water changes to keep my ca and alk in check though. For that I dose kalk in my ATO. Dosing also keeps the ca and alk stable, no swing between water changes. I have just started to dose Koral Color it see if that stuff works but I have my doubts.
 
honestly my tank just do 5gallons water change every sunday. and my oponion is all you need just stronger skimmer. (mine is Royal Exclusiv Alpha 200
Cone Protein Skimmer ) and good light. that is all i think about my tank. maybe im just lucky or so i never check my cal, alk level at all. i dont check anything on my tanks.
 
what salt mix do you use?
I know you said you never check ca level, but curious if you can run a check to find out what it is.

I am wondering if it may be irrelevant to maintain ca at 420, even if ca is 42, as long as there is ca, the corals will consume it.


BTW. I notice all those pictures are from september 2009, how about some more recent pictures of the same pieces and fts.

thanks

Is this guy running any kind of reactor? what size of tank? how big are his sps colonys? is he using a "hot" salt mix like reef crystals or similar?
