Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
For those that are running a T5/MH combo, I would love to hear some of the combinations.
Currently I am running a phoenix 14k and 4 t5 - 2 420nm and 2 460nm.
considering a change on the t5s
Any tumbling will cause some break down, but if you keep the tumble slow it will be kept to a minimum.
Foam filters will prevent the media from leaving in general, but depending on the filter, it will not catch all of the smaller particles.
Taz,
Can you help me understand why you feel the new bulbs will resolve the issue?
It sounds as if you are saying the only time the issue goes away, is when the impacted area is dark.
It is a little late in the game, since entries are due on 12/31, but I figured I would post the contest anyway.

My understanding is the flow for Carbon and GFO are conceptually the same.
The slowest possible flow applies to both media. This ensures the most contact time as the water passes through the media.
The difference in flow for GFO is a result of a GFO property, whereby GFO clumps together if it...
To answer your question, not every tank requires a skimmer. However, a skimmer is usually recommended if you are keeping SPS since they are less tolerant of "dirty water".
This is not to say you cannot keep SPS without a skimmer...as I mentioned before..too many variables.
Everthing looks great!
It seems like you have made quite a few changes in a relatively short amount of time.
Do you think you will be able to parse out which products were having an impact?
Not sure if they are already broken.
I would not use a chisel. Not enough precision for my taste.
Dremmel and/or Hacksaw would probably be a better option IMHO.
I think when people give advice like, a skimmer or ro/di is a must have, they are saying this because they are playing the percentages.
There are few true "must haves" in this hobby, since there are so many variables involved.
However, I also feel that suggesting the need for skimmers or RO/DI...
Just guessing, but that looks like a bad seal based on the pic.
silicone caulk looks like it disappears in the corner.
i am not even close to a caulk expert, but at the least I think he would have to drain the tank, dry it out, seal it, cure, and re-fill.
What a PITA!!!
Sorry to hear about...
So if we are to assume that the data in this link is accurate, the spectral shift that has been talked about would be limited to flourescent lighting.
While all bulbs lose PAR (which of course presents a different problem), nuisance algae relating to old bulbs should not occur with MH bulbs if...
Thank you for the link. Much appreciated.
Here is a link from RC discussing this topic in 2005 that I just came across.

Seems there was varied input at that time as well.
