Wolf, Thanks for the feedback. The method you described is how I currently change really large volumes of water. My fear in using this technique is that I'll wind up draining a significant percentage of the new water with the old stuff. IMOHO, getting the concentrated old stuff out is a top...

Another sugestion... If you're going to use plexi for the dividers, use sheets as thick as possible. I used thin plexi and it bows a bit.

Crude Filter Kludge Requires: - 1 bucket or old tank - 1 Powerhead - Clean Towel, sponge, etc. (no soaps or chemicals) - 1 5/8 inch or appropriate-sized hose Try making a DIY sump and overflow. Rig your system so that the water drains out of your tank and through the towels/sponge. You'll...

I notice there's been a lot of lively discussion re: treatment & diseases of fish, where we all make recommendations to one another primarily based upon our own successful experiences. What about cases where medications/treatments failed? What products and/or procedures have failed to live up...

Oh, I almost forgot... aside from water changes, two means of elimination Nitrates are: -Providing an environment for anerobic bacteria... (i.e. a deep sand bed, coil denitrator, etc.) -Introduce Nitrate-Eating plants... (i.e. a refugium or that pesky hair algae). As a bonus, the plants eat...

7up, I've always found the phrase "Nitrate Factory" to be a little strange, but here goes: -The idea of biologigal filtration is to convert bad things (waste) to harmless things -Ammonia is worse, followed by Nitrites and then Nitrates -Trickle filters, crushed coral, UG filters, etc. excel at...

The inhabitants of your refugium should happily devour waste stuffs from your show tank. IMOHO, that's the idea of a refugium. :)

Here's a Juvenile Koran (actually, the text it was name for should be spelled Quran or Qur'an, but what the heck)... Here's an adult Koran... BTW, I've seen them much brighter and prettier than this... Here's a juvenile Emporer (Imperator)... Here's an adult Imperator... hope this helps!

Thank Fat_Ed, but Old Yeller is right... I stole the photos & instructions from a site ;)

Surf, You may want to post this one in the equipment & DIY group.

Clipped from a site... Step 1 Ok, first buy the wood. Don't skimp here. The whole look of the stand will depend on the quality of the wood you buy. I went with 3/4" A/C plywood. The A/C are grades of the sides of the plywood with A being good (no knot holes, and C being Ok, a few smalls ones...

Thanks, Mariner! I was basically of the same opinion until recent power outages caused my to contemplate the relationship between corals and fresh air further. A few weeks ago, I was travelling on the East Coast, when my power was shut off for ~10-12 hrs! Yes, 10-12 hrs. (Long explanation)...

Probably a dumb question.... As I've now got corals and various sedintary inverts all over my system, my infrequent water changes are presenting a problem (I say infrequent because I'm so lazy that water changes are a rare event). Anyhow, If I try to do even a 15% change in the tank (after the...

7up, Something to keep in mind is that Hair Algae is nature's way of balancing other problems in your system. I don't think 10PPM NO3 is a problem... in fact, some folks that keep clams and such argue a bit of NO3 is necessary. My 100 gal. is much higher than that (This is my only tank w/o a...

Thanks, Newbie. I think that's a project for next weekend ;)

Hey 7up, Let me take a stab at your questions... 1)-For a 75, a 20 gal sump would be OK. Generally, IMOHO it's a good idea to go with as much sump as possible. The "H" in 20H might be a problem. As you'll need the two ends for drain line and return pump, you'll probably want the system to be...

There are really two purposes for having a refugium: 1. To improve water quality 2. To breed critters without predation Some people have the luxury of placing refugiums above their skimmers and can, therefore, build skimmers for both purposes. I don't really have that luxury. I do, however...

I've performed the following mod to my overflow returns, in order to minimize the risk of flooding from the inevitable California power outages.

I've got 2 CoraLifef (1 8W & 1 25W) and they've worked OK so far??? Easy to hook & use...

The idea is to get the fish to eat it, thereby enabling them to excrete noxious garlicy oils that repel parasites. I don't believe floating a bag of garlic in you tank will work. I believe the idea is to get the fish to eat the garlic any way you can. Don't float the bag - Feed the fish...
