View Full Version : what else to test for?

10/26/2006, 05:11 PM
OK.. I'm still having water problems and just can't put my finger on it.

My toadstool, hammer, frogspawn, and polyps just arent opening up like they used too.

But my Zoa and clam is doing great and growing very well.

The only thing that is low is my Alk which is 7 dKH. (I've been out of town the last few days and haven't added any buffer) I mostly try to keep it around 9 dKH.

Here are my parameters: All test done with Seachem unless noted.

Nitrate, Nitrite, & Ammonia= 0
Salinity 1.025
Phosphate .015
ALK (7 dHK Seachem) (6.44 dKH Salifert)
PH (8.1 Seachem) (8.2 Salifert)
Calcium (425 seachem) (430 Salifert)
Magnesium (1230ppm Salifert)

What else could I look at?

I also changed from MH's to T-5's but the first 2 weeks I had the T-5's every thing looked great.

I am far from being an expert, but I've had problems with borderline Alk at 7dKH. Try to bring it up a little bit. The rest of water parms seem ok, though you might want to bring Mg 100ppm higher.

I usually keep it around 9dKH but I've been out of town for the last 4 days and haven't had time to add any additives other than Lime water as top off water.

When is the last time you did a water change ?

What is your water change schedule ?

10/26/2006, 07:02 PM
I do about a 30 gal water change every 2 weeks. I'm dew this week end for one.

Well then I would focus on getting your alk up for now and see how things improve. The regular water changes should be taking care of all of your trace elements.

While raising the alkalinity is good, and maybe magnesium too, I doubt either is impacting soft corals, and I'm not sure why they'd be suffering now based on those reported vlaues. The problem may be elsewhere.

They were good before? How long? Any new organisms in the tank?

Well.. I think now that I checked my Magnesium my problem may be with my lights. They are some what new.

I have asked a few lighting guru's about and my lights are on too long. I'm going to work that end of it and see what happens.

OK, if that works out let us know. :)
