    Hi All,

    In designing your own tank/stand/cabinet is there any problem with having a closed lid system ? I am thinking of having a lid over my tanks, about 200mm deep, where I want to house my Vertex lighting.

    Is this ok?

    Is it better to have the tank open ?

    Would this damage the lights at all ?

    Any other considerations ?

    Thanks
    Victor

    You can add a lighting hood but just remember it must be well ventilated.

    By this do you mean holes on the sides/back of the hood (natural air flow) or forced cooling (with fans) ? The Vertex lights themselves are made of alluminum so act as a heatsink anyway for the components.

    I would leave the back of the lid open for the humidity and heat to escape. That way you dont need fans.

    Lids are good if ventilated. Many really nice fish are closet carpet surfers who's only wish is to die a dry furry death.

    Also your normal fish will fall out whenever you shake your tank without the lid on.

    Led units needs to be well ventilated. If the base of the led chip overheats it shortens the lifespan of the leds drastically.

    On the other hand you can loose fish due to carpet surfing. Especially in rimless tanks. Euro bracing and the fish tend to hit the brace, but it still can happen.

    Glass sliders ontop of tank, under the lights, that again prevent gas exchange, gets wet, dirty and block a lot of the light. They are in your way when feeding and will one day break.

    Net covers, depending on the design, works a lot better.

    Never though about this. A rimless tank with hanging LEDs and a fine, black barely visible net around he black silicone top edge could really solve a lot of my problems wih rimless.

    Speaking of which, do you guys know where to find suitable netting for this? I had some decent stuff years ago but I've run out and can't remember where I got it. Needs to be thin so that it won't block light and fairly fine to stop jumpers. 1cm hole size would probably be ideal.

    hassle with this idea guys, is it makes it a mission to remove and replace whenever fiddling in the DT, what would you use to secure it, velcro?

    Hmmm.......There are many ways going about this.NO lid means more evaporation damage on lights sometimes.Fish jumping out trying to defeat gravity.Nets prevents fish from jumping out ,but still allows damage to lights and evaporation.Evaporation also leads to dried salt all over the net.Lid does not allow gases to exchange Depending on Type (my lid allows it perfectly)stops fish from jumping out.can protect light in away.Lid with glass cover over light!!This is by far in my opion the best option.This allows less evaporation.stops fish from jumping out.Now I have this design in my tank where I have open corners on either side of the glass lid,that allows me to drop food inside.also on the back has about a 2cm gap that allows my cables and air line from my filter to come through.This also allows gases to exchange.The glass actually stays very clean and allows a lot of light to come through.These are just showing the good and bad sides of lids,non-lids and nets!Hope this helps

    WOuld a cover over a light source - I was thinking of using clear perspex - have any effect on coral/sps growth at all ? Do the livestock depend on the heat from the beams or really only the light ?
