Calcifying problem

Oh yeah, are you aggressively shaking Nitrate reagent number two for at least 30 seconds before testing? That makes a world of difference in accuracy!
 
Par 38s on one tank, 80 degree optics at about 8 inches off the tank, then t5s on my other tank that are a year old that will actually be replacing this weekend. My photoperiod is run off a carribean photoperiod. Im not sure exactly what its at now, My Apex takes care of that.

As for the kits, the mag is rsm and only about 5-6 months old. I ordered all new kits just to verify that they work. I am kinda going crazy with this. I also ordered 2 part, and zooplex and phytoplex to dose with.
 
At the risk of seeming silly, that age on the t5s and the distance of the par 38s could be working against you. (Don't hit me...please don't change the t5s all at once!)
 
Im not going to change to t5s at the same time. What height should the par 38s be at. The corals are on the bottom of a 40 br at that height. So the bulbs are actually about 2 ft above the corals. 15 inches are water with the 80 degree lens
 
Most people are running them at 8"s, some are at 6"s.
Have you checked your water for gelvins? They could be filtering your light, inhibiting growth.
 
Im not sure what gelvins are but i know the water is diffusing and reflecting the light. I have tried my raising my sps slowly on these lights but nothimg wants to grow much higher.
 
Do you have any pictures? Could it just be your perception that things are growing slowly? Also, some corals do grow much more slowly than others and most SPS have to have a stable base before they start to show much growth at all.

well i picked up a carbonate hardness test real quick and these are my up to date parameters:


amonia: 0
nitrite: 0
nitrate: 0
ph: 7.6
calcium: 420 ppm
phosphate: 0
dkh: 8-9
mag: 1250

any thoughts?! this is killin me watching this


I would say your Ph is a little on the low side too.
 
You list your PO4 and NO3 as zero. Have you had either tested with a Hanna meter? If they are truly zero, the corals are starving. "Some" nutrients are needed in a tank. If you are stripping all nutrients out of the water, there is nothing to help feed the corals. This was mentioned briefly on page 2 of the thread. Curious what brand of salt you are using. Also, what type of skimmer are you running on your tank?

Keep in mind that trying to watch corals grow is like watching paint dry. Corals go through "growth periods" and if you have the slightest alk swing, that can stunt growth for months! It's only after stable conditions are achieved for a prolonged period of time that you will start seeing new growth. Of course, we are all very impatient and want our corals to grow NOW! If only the corals listened...lol.
 
Heh thx craig. I have not had my tank tested with any hanna meters. Im in upstate ny and I dont know of anyone that has any around me. I use reef crytal salt mix and i use a octopus xps 1000sss skimmer. And my skimmer took some time to adjust but that thing skims like crazy. I understand corals grow slow but the skeleton is actually getting smaller and almost decomposing? Im not sure if thats the proper word but for example ive had a branching 2 head frag of frogspawn for a couple months. The heads have split into 6 heads but the skeleton between them is completely gone except for about 1/8th inch from the heads.
 
Strictly out of curiosity, do you live in a green, well insulated home? Double pane windows and all? Some people experience elevated CO2 levels in "efficient" homes due to lack of ventilation. This has discouraged calcification by acidifying the water! i know, it sounds silly...but documented!

I should of actually mentioned that. My system is locacted in my basement. I run a fan nonstop near the basement door. I tested the ph in the afternoon. Other than more circulation how can i lower the co2 levels in the basement.

Can you extend the airline from your skimmer to get air from outdoors. Another option would look into co2 scrubber bulk reef supply carries them

You know not all sps grow fast, some grow painfully slow.
Flow: higher flow will slow down sps growth, It make the coral grow a thicker stronger skeleton.
Nutrients: Too low of nutrients can cause slow growth. doubt that is an issue here.
food: Food will increase growth.
Light: well it depends on the coral.

Thx i was debating doing that and throwing some plants around the tank. I will get some air tubing tomorrow
