no more open tops for me!!!

OK, if I didn't know any better I would swear I was keeping lemmings instead of fish..... I have had 5 jump ship in the past 6 months (OK I should have learned before now) and die in the floor, most recently tonight. This is why I will not have another open top tank and there will be a fix in place on this one by the weekend...

Several of the fish I plan on keeping are known as jumpers so I'm thinking about doing the clear mesh top like in this thread.

Yep Lowes in the lighting dept. The grid we use to make frag racks with. Yep anything between the light and the water will diffuse the light but I agree something has to be done about this, it's a fare trade.

Thats what I like about the thin mesh tops. It takes a little more DIY, but it should block little to no light.

Matt turned me on to light grids (from a hardware store) as tank covers. I have them on a 90 and a 125, both lit by halides.

I can tell no difference in the amount of light in an uncovered tank and one with the light grid. Matt told me they do not block light, and as usual, he's right.
Grids are great because they let out heat, let in light, and keep fish safe.

The only way grid will block light from a halide is by using 2 or more over each other, some do this to acclimate SPS. Halide light is to bright to be reduced to any noticeable level, but PC can show a marked decrease IMO.

I would think the Halide would be more effected by the grid because it is a single point light source.

Halides produce an intense amount of light, it would take more than a single egg crate panel to block that light to any noticeable level unless you were to use a higher K with lower watt bulb(s). When we tried to acclimate some of the coral in Rogers system we had to triple then double and stager the grid to decrease the light, that was with a 2X250 10K DE setup at the time. BTW if you are going to acclimate your coral this is the easiest method aside from resetting timers.

Here is an interesting read on egg crate.
Link

When reading the thread pay particular attention to anthonys comment about the height of the egg crate and bulb for mh before you get too excited

Egg crate will slightly decrease PAR but i think its the best option for those that need a cover. It still allows for evaporation and does not need to be cleaned frequently like a glass cover. IMO, for those that need a cover the small loss of light outweighs the chance of losing a fish due to jumping.

Also as a side note i have seen eggcrate that has a thick/thin side and some that didn't. If you have the stuff with thick/thin i would point the thin side up as the thread suggests.

Could it be that you have current in water, or a bully chasing everyone "up". Kinda weird that's so many are jumping. Why do they want out?

joyski, funny you should ask that....that is what I told my wife was that I thought the G/S maroon clown was throwing them all from the tank but I have never seen him act aggressive toward any of the other fish.?.? I bought some light grid today and will fix the problem of the open top tonight....

That's quite possible if there is a leaking pump, heater etc it could cause that sort of reaction but most likely it just causes dead fish. You don't have Hydor in your tank by any chance do you? Some of those models had voltage problems for a while.

What do you all use to cut your egg crate?

btw Lowes Nitro has it in the ceiling tile area.

I used a pair of long nose straight tin snips. or a pair of side cutters works also. any hand saw or power tools would tear it apart I would think.

Dremel with cut-off wheel, like knife through butter.

Okay I have to say I've had the egg crate on my tank now since Saturday and with the LEDs I think I'm loosing light.

Are there any alternate ideas for something to put over the tank? I'm thinking of going back to the glass tops.I feel like I need something to keep my jumpers in the tank.
