WAVES Posted November 2, 2007 Share Posted November 2, 2007 so I checked out the milwaukie brand unit (since the other is out of stock), it reads this: Range 0.00 - 2.50 mg/L PO4 Resolution 0.01 mg/L Accuracy ± 0.04 mg/L to 1.00 mg/L Someone help me out, what does .04 to 1.00 mean? Does that mean it can be anywhere in between, or does that mean something like .04 PER 1.00 mg/l? Sorry Dan,,, ill shut up now and quit hijacking your thread.

I'd assume that meant it was accurate withing +- .04 mg/l until the result is up to 1.0m/l then all accuracy measurements are off. Quote Link to comment Share on other sites More sharing options...
drock59 Posted November 2, 2007 Author Share Posted November 2, 2007 Nyles, you may have hit the nail on the head. I have been having constant and pH issue. I have tried all the suggested remedies over at RC and nothing seems to work. However, if my pH is not swinging a bunch, just hovering down low at 7.9-8.0, is that a real problem?

I would say no, as long as a ph is 7.9-8.4 area and stays stable it should not effect to much. Quote Link to comment Share on other sites More sharing options...
Nyles Posted November 3, 2007 Share Posted November 3, 2007 I agree, as long as its not swinging ph rapidly, like dosing all your kalk for the day at once... Quote Link to comment Share on other sites More sharing options...
drock59 Posted November 3, 2007 Author Share Posted November 3, 2007 Obviously, this problem will not be solved in a short time frame but I want to recap what we have covered. Ph= fine as long as it not swinging Levels=A little low on the calc and mag but nothing drastic Phos=possible but going to be difficult to test. Lighting=I am still considering this possibility, but I hate to mess with it too much. New bulbs around Christmas. Still consensus that Phoenix 14k is the way to go on the DE front?

Yeah I agree with everything you have covered here... phoenix 14k's are great bulbs... as for lighting, maybe you could try playing around with your lighting schedule, cut it down some or increase the time and see what happens...

drock59 Posted November 3, 2007 Author Share Posted November 3, 2007 I cut it by an hour and I will see what happens over the next few weeks. Quote Link to comment Share on other sites More sharing options...
impur Posted November 5, 2007 Share Posted November 5, 2007 Dan make sure your alk/calcium are on the high end with a lower pH like that. My tank has a similar pH and swing, and i've noticed much better results when my alk/calcium are higher, like 9+dKH and 450+ppm calcium.

drock59 Posted November 6, 2007 Author Share Posted November 6, 2007 Cool Miles, thanks for the input. I will try and get my Calcium up a bit more and I have kept my alk at about 11-12 for a long time. The pH thing is really annoying by the way.

impur Posted November 6, 2007 Share Posted November 6, 2007 No doubt. Seems to be the most common problem. Good luck. Quote Link to comment Share on other sites More sharing options...
drock59 Posted November 17, 2007 Author Share Posted November 17, 2007 Well its been a bit over a week and I have yet to see any real improvement. However, my pH has been ridiculously low. I have a window open in the fish room and it is super cold, but lots of fresh air. Im dosing kalk, and my alk is up around 11dkh. What the heck? Anyway, I thought I would share some before and after pics. Before Today Before Today Some other brownies And lastly some corals that look decent a year ago: Full Tank: Quote Link to comment Share on other sites More sharing options...
impur Posted November 17, 2007 Share Posted November 17, 2007 Thats just too wierd that some are brown while others aren't. Have you tried raising the pH range in your CA reactor or taking it off all together and dosing for a month or something? Quote Link to comment Share on other sites More sharing options...
Nyles Posted November 17, 2007 Share Posted November 17, 2007 I agree, I raised the ph in my cal reactor and it solved my issues. Worth a try anyhow if your not already up in the 6.9 range. Quote Link to comment Share on other sites More sharing options...
drock59 Posted November 17, 2007 Author Share Posted November 17, 2007 I thought it was weird that just a few select corals are brown too. My reactor pH is already about 6.8-6.9. Ive had the reactor for about a month and a half but this problem started about 3 or 4 months ago. I dont think its the reactor. Maybe my skimmer isnt sucking in enough air to fully aerate the water. Seems like a stretch. Quote Link to comment Share on other sites More sharing options...
WAVES Posted November 18, 2007 Share Posted November 18, 2007 FYI I bought a phosphate colormeter after the first part of the discussion and I discovered I was wrong. Dan if you end up in PDX, be sure and bring a water sample. Quote Link to comment Share on other sites More sharing options...
WAVES Posted November 18, 2007 Share Posted November 18, 2007 Hey look at that my 1111 post. DOH! Ruined it! Quote Link to comment Share on other sites More sharing options...
drock59 Posted November 18, 2007 Author Share Posted November 18, 2007 Joel, will do. This still kind of baffles me. Now I am seeing a bit of lightening in some corals, which usually means I need to feed more. However, I dont want to feed more as I do not want the corals that are brown to become more brown. Such a dilemma. Quote Link to comment Share on other sites More sharing options...
izzypop Posted November 18, 2007 Share Posted November 18, 2007 Cool Joel on the colorimeter. I am so surprised they haven't caught on with so many people keeping sps. Quote Link to comment Share on other sites More sharing options...
drock59 Posted November 18, 2007 Author Share Posted November 18, 2007 I think people would rather spend the money on SPS than a colormeter. Quote Link to comment Share on other sites More sharing options...
reefgeek84 Posted November 18, 2007 Share Posted November 18, 2007 I think people would rather spend the money on SPS than a colormeter. I agree...although I am considering looking into one. Quote Link to comment Share on other sites More sharing options...
Nyles Posted November 19, 2007 Share Posted November 19, 2007 Maybe my skimmer isnt sucking in enough air to fully aerate the water. Seems like a stretch. Funny you mention that, when my system browned I found salt creep on the air intake on my skimmer, limiting its performance. Quote Link to comment Share on other sites More sharing options...
Jay Posted November 19, 2007 Share Posted November 19, 2007 After reading this entire thread I want to thank everyone for awnsering many of my questions. I am also struggling with brown sps corals and now have many new ideas to work from. Thanks. My tank is looking better lately but still have brown sps corals to deal with. Can the color return? How long for that to take after everything is corrected? Jay Quote Link to comment Share on other sites More sharing options...
Nyles Posted November 19, 2007 Share Posted November 19, 2007 I have seen some types return to coloring in a few weeks, while some of the SPS I have take months and months. On average mine took about 3-4 weeks, but like I said it varies on species. Quote Link to comment Share on other sites More sharing options...
