Corals vary from 4 months to about 7 months top. Thanks for te compliment.Viv said:Very nice! I like the way you showed that, I was thinking as I was looking at the individual corals what it looked like in the tank as a whole...and then got to the full tank shot...are they new corals? They look great!
That's the thing though, the sump is supposed to be a setteling area. Deatris breaks down to it's component parts (most annoingally for us nitrate and phospate) very quickly in a high flow area like a filter sock. If you were to just let it settle out on the bottom of your sump, then suck it out every week or so I think you would be much better off for it then changing the sock every 2 days.Whiskey: I've been running filter socks since day one, it has always helped to keep particle matter out of the display, and also keep stuff from settling in the sump. I change them every 2 days(before anything really nasty can build up).
I have no idea how long it will take to fill up, just that it will be fast, because immagine how much sand you would need to fill your tank/sump with a DSB then figure that will last around 3-5 years. The problem here is not that it will fill up, but that when first added it is unstable, then it has to establish it's self, then it starts pulling nutreants in and anamals grow down in there, then it starts to get full/crash. In a normal DSB tank it takes about 1/2 to 1 year for the unstable bit/establishing to get over with, then it pulls in nutreants for a couple of years as anamals grow, and finally near the end of it's life starts to get full, and cause algae, then finally crash. I am worried that "sweet spot" might be really short with yours causing more harm than good.The remote DSB is more of a trial more than anything.Like I said, I would have definetely loved to get a bigger skimmer, just have no more room. Do you have any idea how long it will take that amount of sand(about 40 lbs) to fill up, I have no problem changing it out sooner than 6 months, I just don't dont know how long. Ideally, my nitrates will drop to 0 from 7, and phosphates will remain at 0(D&D Merck Test Kit), time will tell. I will have to run more nitrate and phosphate tests to keep a closer eye and what my levels are doing.
So you are running about a 12 hour total photoperiod, with a 9 hour MH photoperiod?My lighting cycle is a bit longer than what many people have. Mt actinics go on at 7:30/8A.M. One Halide comes on at 8, the other at 9. 7100K come on around noon. One halide off at 5, the other off at 6. Actinics off at 8. 7100K off at 7.
Thanks for the compliments.
Not really unclear, I just wanted to simplify it.rutz81 said:Whiskey:
Your lighting addition is correct! Sorry for being so unclear..lol
Indeed it does I have no doubt that your nitrate will drop like a rock, but you are exchanging nitrate for a phospate sink that can only hold so much.I was reading a thread from Calfo about how a remote DSB in a bucket works great to reduce nitrates,
They are not, the bucket would do the same thingso, I took that and rather than using a bucket, I used a section of the sump. Maybe I'm not seeing how it could be different?
Here we disagree, you have a filter sock before your DSB section, in this sock your particulate deatris breaks down very fast into phospate, and nitrate, and a host of other things, bactera need to make a soup to pick up these elements, the flow will sweep these things right into the DSB section. I don't know if you would be better off with or without the sock, but I think best case would be to have ONLY your skimmer output entering this area, but it would still fill up.Also, as long as I have a filter sock before the entrance into my remote DSB section the usual DSB animals shouldn't be able to survive without their proper nourishment(detritus).
A needle wheel skimmer can skim wet too, it is just a matter of setting the water level high enough, is yours maxed out? Particlate matter will settle out in the sump, where you can syphon it out with your water changes, if you have the setteling area there. That is what most of us do.Not using a filter sock would work great if I had a beckett skimmer and could skim wetter and remove all that detritus, but, being that I can only skim somewhat wet, I have to rely on other things to remove the particle matter, I think?
I use my nitrate as a tool, I have yet to attain 0 either, but that tells me that there is something I am not getting clean, deatris on the rock, skimmer not wet enough, or rocks not done sheading yet. The nitrate is not going to kill anything, so for the time being I use it to tell me how clean my system is, along with watching out for algae on my glass.PLease correct me if I am wrong on any of my ideas, I am just putting a few different theories I have read together into a mixture that will hopefully turn out o.k..
