    Non-Member not going to join...

    in General Discussion

    Just like most everyone else, I was a bit leary of joining. But the $20 is worth the For Sale and Group Buy sections alone... Also being that it's a local club, people here are genuinely out to help.

     

     

    Hey I was the one who started the food thread in the first place, and I was slightly dismayed by seeing it moved as well, however I understand why it was done. At first I too was interested in getting into WAMAS, till I inadvertantly was practically given an outstanding tank by another meber, who talked about WAMAS, after poking around the general discussion area, it was an obvious choice to join.

    Is there such a thing as too much light?

    I know the RGB spectrum, I'm not completely daft.

     

     

    I mean to ask could the brightness actually cause harm to the fish, i.e. blind them everytime the lights come on.

     

    I know the RGB spectrum, I'm not completely daft.

     

    I slept though chem, not biology :wink: I passed my spectrometer test in 101 thank you. What I'm having trouble comprehending here is the units they use for LEDS, I'm not sure what they mean, I have a rough grasp of the spectrum in terms of 10K 20 K 15K etc. How ever in theory could this be duplicated with the application of LEDS?

     

    My main question is what is 25,000MCD, 60,000 MCD, 15,000mcd etc what is MCD is it similar to or a sort of specrtum measurement? Or is it a measure of brightness like lumens, foot candle, candlepower (yes i relize those are diffrent types of measure)

     

    So is it possible to get the correct amount of intensity out of leds to be as good as a MH buld, if you spend the time to make your own? Anyone care to shed some :idea: on the situation?

    I showed the led fixture to some one else, and they decided to buy if for $60 and put a screen in front of it and use it as "mood" lighting for his rec room, good riddance, it ony cost me $20 minus the resistor and wiring work done by hand. I've read more about the led fixtures, and it looks like you need to buy the ones meant for marine use any way.

     

    I'll go with a PC light foxture

    I don't know wether or not this is a stupid quesition but, I'm working on building my own hood for a 5 gallon nano tank....

     

    In the hood I've made there are 125 LEDS being fed by of course a massive 12 volt DC power supply.

     

    90 are white LEDS

    35 are blue LEDS

     

    I hooked it up in a room roughly 25 by 20 feet with the lights off, and it was like an air plane was comming in for a landing!! :drink:

     

    It lit up the entire room like day light, the olny reason i did so many is because my calculations showed that 125 LEDS = 10 watts (roughly)

     

    Yea I know i coulda saved money and gone with a florescent fixture, but the LEDS were brighter (maybe a mistake?, and last longer)

     

    Is it the intensity of light, or the amount of light that corals need? I also don't want to blind the :bluefish: :fish: , I'll be putting in the tank.

    I can just see a snail/welk jumping an unsupecting fish like a DC mugging lol ... :lol: , but I found stuff on google as well that said they were oppertunistic feeders... means they'll eat what ever they can get their grubby little hands ???? on, dead or alive

    RDSB/REFIGIUM nitrate reducer?

    Whats that pvc fixture off the back of your tank? With the inline pump... I have an inline pump sitting around my house that in theory pushed 800 GPH of water i think... it's not written on there and I have no idea how to calculate it. Anywho I was going to use one of those, in some application or another... to drive my UV sterilizer when i can afford it, but I thought for now i could use it to drive the bucket for now, i think if i did a closed loop system it would work, any opnions? :bluefish:

    IRT having the pump push or pull, I'd go with push. Some grit is bound to get kicked up from time to time and you really don't want your impeller being subjected to that. It would be even better if you set the bucket up where it can be gravity fed from your tank.

     

    Why would I want to gravity feed it? I'm asking not arguing? Whats the advantage...? How would I do it? and what would prevent it from flooding in a power outtage?

    Current/Waves/Flow

    · Edited by jason the filter freak

    Since I have a pretty decent tendancy to start argumentative threads I thought I'd ask this, and becuase my power sweep power heads keep sezing...

     

    Whats the best way to create current in a tank, I have a 55 gallon tank with about 60 - 70 Lbs of LR, it has a silica sand bed.

     

    If I don't count any of my power heads that are currently in the tank (5) the olny thing creating current are two out puts from a fluval 305, and 405 (directed down over my heaters) and on the oppsite side of the tank pointing along the lenght and toward the surface to churn the surface is the output from my sump (400 GPH)

     

    Whats the best way to create current/waves/flow that's healthy and conductive to the tank :fish: ... 1. where's the best place to place power heads, 2. where/ which direction should the be pointed, 3. how much current is nessecary, 4. how much is too much?

     

    I'm not interested in sea swirls, or other similar devices

     

    I plan to make some of these with Maxi Jet 900's http://www.wamas.org/forums/index.php?showtopic=8317 I was told my 1200 would be too much for the tank.

    RDSB/REFIGIUM nitrate reducer?

    in General Discussion

    :why: uNFORTUNATELY, IT SEEMS i CAN'T find anything byt silica sand, nor am I guessing the other stuff is all that cheap... there are no marine supply store around be, and darned if I'm going to pay shipping and handling on .... sand. I'm guessing though if the water flow can be kept fast enough I shouldn't have a problem with it... Next question. I ready most of the thread as well, but being full time in both college and the buisness wolrd I'm struggeling a bit here...

     

    What's any ones opnion here, should i have a pump pushing water into the RDSB, or pulling it out?
