Temporary high phosphates for SPS?

[Proteus]

I guess it depend on the state of sps now. If its healthy it may not notice.
Ie: I'm looking after a few pieces that were in the state of stn. I dipped th all in RPS and added to my tank. Last night I removed LR from sump to put in new skimmer stand and after puting rock back in I stirred up some debris most Likely bring nutrients. Today while light come on I noticed that while all corals looked good one of the affected pieces had turned to RTN.

So I would suggest maybe to be prepared on a WC it corals react badly

I have quite a bit of nitrates in my tank and never had a problem with SPS. Now my nitrates are around 5ppm but last month it was at 40ppm.

My sps always have been doing great no matter what the nitrates. Recently I bought 10 fresh cut SPS frags that were kept in ULN tank and very light in color, almost bleached. I only lost one frag and they other are starting to color up nicely, not turning brown at all, rather getting some nice fluoresence and colors.

From about mid June to September my temps go from 77 at night to 81 (or 82 on a really hot day). And this is with central AC. Without central AC the temp will go beyond 83 which is too high for my comfort level :-) At any rate, my tank seems to do fine at 81/82. As already suggested, do make sure your tank is well oxygenated (which most tanks are anyway, with skimmers, etc) if your tank is trending to the 80s.

Well, mine was getting up close to 82 a couple times already when we had warm weather. Luckily, the warm spells only lasted a few days so far this year. But it is going to get much warmer the next couple months, so I think it would have been big trouble.

We do have central A/C. But ironically, the basement warms up too, when it runs, as the air circulates the entire house. We set our A/C temp at 76, which is still warmer than most of the year. The problem is we have a 3 level house, all exposed to the northwest (including the basement level, as we are on a hill), and the sun really heats it up later in the day.

I ran the 2 tanks combined on 1 sump last summer and it worked well. The other advantage is that I decommission 2 pumps (return pump and skimmer) and one sump, so that also saves heat and electricity. On the combined sump I have a single Sedra 20000 with multiple T's that returns both tanks (one up a floor level) as well as to my bio pellet reactor, chiller, and GFO/carbon reactors. It is a very powerful pump, with lots of head pressure, and quiet, too.
