growth has stopped?

[daveonbass]

ok, all my params are at or near NSW...n and p are both undectecable through use of Biopellets.

I was trying to get my Biopellets to work for months...then finally I got them started. and ever since the N and P were down to 0ppm the tank started to grow like crazy. I loved it.

But in the last month, the growth has seemed to slow and/or STOP in some cases. My best guess is that out of my 6 blub ATI, only two were replaced recently...and the other 4 Blue+ bulbs are old. Could it just be that the light has shifted and the PAR is now lacking for growth?

Other events are the addition of a HOB(side for me) fuge that is houseing 12 Banggai fry that are growing out there for a while to take advantage of the DT water. But other than the babies, the tank is the same...just the blubs are getting old. IF this is the reason...then can someone give a brief explanation why my growth would just stop...and not slow, or have any color browning out. The frags all look great still...and have good color and PE, but just haven't grown in the past month.

Thanks in advance...and yes ASAP I will be getting more Blue+ bulbs, but for now I want to know if my tank is experiencing something else as a problem.

On a side note...the non SPS corals all seem to be growing at the same steady pace, this is the main reason I'm asking...LPS and ric growth is still steady, just the SPS seem to have stopped.

Any ideas...?

If all your parameters ok , try increase feeding .

sorry, I should have mentioned...

I feed the fish in the main tank twice a day: mysis, Pellets, or flakes.
I feed the babies twice a day: live BBS, Frozen BBS, chopped Mysis, or crushed flakes.
Twice a week I feed "Papone" at night to the corals.

Other than that I have been monitoring the way the Biopellets have been effecting the corals. So far (till the sudden growth stop) it's been very positive, and the corals responded with great color changes and growth. But lately they just seem still...

So....

Should I "still" try a little more food?

fish poop provided by:
2 occelaris clowns
4 chromis
1 Magnificent Foxface
1 yellow tang
2 Banggai cardinals
and now
12 banggai fry

could there be too much fish poop...? or does it still seem like the lights are to blame due to old bulbs?

thanks in advance

My bet is that you need to replace your bulbs,I have similar set up with bio pellets,but about 6 month my SPS corals slowed down in growth.I changed bulbs in my fixture and within a week I see new growth tips on most of my SPS.

Check very closely for red bugs if you have not already. Almost impossible to see with the naked eye.

+1 exactly what I was thinking. Look at night with a flashlight there easier to see this way.

If it is not red bugs try dosing aminos. You nutrients are so low you can stunt coral growth. This is why zeovit users dose aminos and vitalizer.
