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.
Welcome. By the way, I too like the idea of doors on the end to easily move the sump in and out. One comment on your stand build...it appears the upper frame, which will hold the tank, is supported by the fasteners only (probably screws), through the upright 2x4's. You really don't want the...
Crap! Another weekend refereeing soccer games down in Neptune. Unfortunately I won't be able to make this months meeting. I think at this point John and Bill will have stuff from three group buys for me or Jon....GFH, Glue and Bags and stuff from PA. I'll have to make arrangements.
I have no idea if it would work, but how about those scratch/chip fillers for auto glass. They sell for about ten bucks. I know it's base on acrylates (similar to one-drop super glues). Have no idea how it would hold up on a tank...salt water.
I haven't seen a sandpaper that could withstand glass. I'd be curious as to how you make out. I'd actually try grinding it using a wheel for glass...with great care not to over heat the spot being ground (keep the grinder moving).
As far as drilling...just make sure the glass isn't tempered...
One Fish Two Fish, Red Fish Blue Fish, by Dr. Seuss
Contains everything you would ever need to know, whether you have one fish or two fish, and regardless if they are red or blue.
Sorry, couldn't resist! ;D
I speak with great ignorance, but I don't think any fluorescent bulb is dimable.
EDIT TO ADD: Just searched dimable fluorescent bulbs and found that dimable compact flourescent bulbs are available. Proves my ignorance!
Rafal, those lights looks extremely interesting. I'm curious as to how this all works as well...please keep us informed.
A couple notes about sales of LED lights in the United States - The manufacturers of Solaris (PFO Lighting) have been sued by Orbital Technologies Corporation for patent...
Here are the holes sizes for Schedule 40 (more common type) bulkheads:
1/2 inch bulkhead = 1 1/8 inch hole
3/4 inch bulkhead = 1 1/2 inch hole
1 inch bulhead = 1 3/4 inch hole
1 1/2 inch bulkhead = 2 3/8 inch hole
Zooxanthelia produces glycogen as a waste product that the host may use as an energy source. They can live off this for some time. However, they do need protein and fats to grow which are not available from the zooxanthelia. So they must eat meaty foods to get these nutrients to let them grow...
Hey Bob, I no chemist....oh wait, I am! Since most, if not all of us, mix salt by volume measure, just do what you would do for any other salt. The trace amounts of other goodies that are in different salts isn't going to change the volume measure any noticeable amount. This ain't rocket...
I have to agree with scooter in one regard. We purchased 4 ORA Banggai Cardinal fish for ten dollars each a couple months ago. Now isn't that absolutely ridiculous?
I certainly would run the simple test for CO2. With that large a swing, I think it is the major component causing the pH problem. However, the one thing you didn't mention was your magnesium levels. Magnesium is part of the overall alkalinity / pH thing going on. Make sure your magnesium level...
