Matt,
That is a perfect answer!! Thanks.
(Maybe we should have this conversation on my thread)...
You explained one key thing from your observations over time.
Corals handle/adjust the gentle climb of nutrients/N/P and things that come with the increase.
But Corals HATE drastically reducing N & P or anything else (when you get behind and want to fix problems).
So being ahead of the INCREASE AND maintaining Stability is key.
So many ways to do this. Some work better than others, and some work but you must be diligent on the routines (Any Neglect destabilizes everything).
This time I'm taking a different approach from the Hectic past.
[PHOSPHATE]
-> Even though folks insist that GFO or products like PhosGaurd are a no/no.
--> I think gentle small quantity, or intermittent use is OK to keep P in check if it start getting a little too high, but before it's WAY TOO HIGH. (Running GFO full blast is the problem since it Drops P quickly)
[ NITRATE ]
-> I am weary of Products such as NOPox/Vinegar/Vodka due to side effects. And other methods like bio pellet reactors which can get out of control or cause crashes due to Bacteria Bloom Death.
--> My Approach for N (still not fully solved...takes time) is more natural.
--------> I am increasing my use of MATRIX Media (both in quantity and proper placement/flow)
--------> and (not common) but I am running Two Skimmers (One Wet and One Dry). Since I have the EuroReef and the Spare RLSS DB8i. (This helps with a good Nutrient Export while I continue to feed fish aggressively)
[ NITRATE & PHOSPHATE reduction + Major/Minor Trace Elements replenish]
-> Good old Regular Water Changes, or Extra as Needed.
Of course running the Algae Scubber doesn't hurt. It's self regulating as I have learned.
Don't bother Matt , somehow I didn't see your answer to Wally
Greg, the only thing I would add is that there is never a good time to take drastic measures. Or, maybe I should say, drastic measure should never be taken. Small measure yes- over a long period of time but never drastic measures...
Wally, I have spent a lot of time putting down gfo on my thread and I stopped using it for a long time.. as for nitrates, I tried the natural approach and have had some success with my huge fuge- it's 36 x 36 and 14 inches deep. It is packed with cheato and many other types of macro algae. If I run it 18 hours a day, it can pull n down to below 1 ppm.. but I wonder how many beneficial trace elements it pulls out - not to mention that it is fairly ineffective at pulling phosphate down as well..
Recently I started using gfo again in a passive, step by step method that has worked pretty well for me. I use it in a fine mesh bag (the new black Red Sea bags) and rinse it well which loses me a fair bit of the very fine material... I don't mind. Better down the drain than in my system- even still it is accumulating..
the fresh bag of gfo sat in a low flow area for a week, then it was moved to a higher flow area, a week after and another new bag of gfo was added in the low flow area.. then after another week the older bag was moved to a high flow area, the newer bag was moved to the medium flow area and a brand new bag was added to the low flow area. This has allowed me to gradually and consistently reduce p without any yo-yo. Yes, it's a bit labor intense - and I will turn the high flow bag every couple of days..
each bag stays in the system for 4-6 weeks depending on how often I have to switch out the oldest gfo.
I don't mind phosguard- the aluminum based product you are using but for the money, gfo is cheaper I think because of its higher efficiency..
As for carbon sources like nopox or vinegar etc... I am not opposed to using them either if they are used lightly and consistently.
I take care of a decades old system with a 8 inch sand bed that was a bit neglected for years.. testing showed that n was way over 100 an p over 1 - not .1.
I used nopox for about 6 months to pull the nutrient down or mostly the n. Then I started dosing potassium nitrate on top of the nopox to get p to come down. As well as some gfo to help. So far it's working..
N is now about 5 and p is .7... it's creeping down slowly..
So all this to say that when these products are not over used, they can all be helpful.
I think the biggest downfall of 90% of the products on the market is not the product itself but user error.
We tend to live by the mentra "˜if some is good, then more is better' but when it comes to reefing, this just isn't true very often.
I think I like adding a small amount of a carbon source to a system- it charges up a level of the biotope that is beneficial to the reef.. where I've started using nopox, not only does it help with n reduction but I've noticed a proliferation of very tiny pods on the glass..
The trick is always finding the right amount and not overdoing it..and that can only be discovered by moving in small increments..
