HelifaxNZ Posted October 27, 2005 Report Share Posted October 27, 2005 I've noticed a lot of people without their tank lids. Is there a reason for this? Would having a lid benefit, like reduce evaporation and no fish jumping out? Cheers HelifaxNZ Quote Link to comment Share on other sites More sharing options...
Brianemone Posted October 27, 2005 Report Share Posted October 27, 2005 light and heat. evaporation heaps reduce heat and no top means nothing to block the light Quote Link to comment Share on other sites More sharing options...
jetskisteve Posted October 27, 2005 Report Share Posted October 27, 2005 salt creep= less light Quote Link to comment Share on other sites More sharing options...
lduncan Posted October 27, 2005 Report Share Posted October 27, 2005 If anything, people want to INCREASE evaporation. It helps keep the tank temperature down during summer. High tank temp is a problem (or borderline) for a lot of people. Quote Link to comment Share on other sites More sharing options...
Ira Posted October 27, 2005 Report Share Posted October 27, 2005 Except it means I have to refill my topoff every second-third day when the lids are off and all the windows in my house get covered in condensation. Quote Link to comment Share on other sites More sharing options...
chimera Posted October 27, 2005 Report Share Posted October 27, 2005 Except it means I have to refill my topoff every second-third day when the lids are off and all the windows in my house get covered in condensation get a bigger top up?!!! mines 220 litres (more than 20% of the size of my setup) well worth every cent buying a drum that size. turn the tap on for the day once every 6-8 weeks! my middle names lazy Quote Link to comment Share on other sites More sharing options...
Ira Posted October 27, 2005 Report Share Posted October 27, 2005 If you can figure out how I can fit a 200L barrel right here AND make it wifey friendly, I'll buy you a beer. Quote Link to comment Share on other sites More sharing options...

HelifaxNZ Posted October 27, 2005 Author Report Share Posted October 27, 2005 You could put the barrel in the roof and then you have gravity on your side and it will be out of the clutter!! :lol: Quote Link to comment Share on other sites More sharing options...
Bluetom Posted October 27, 2005 Report Share Posted October 27, 2005 I love the fact that the computer is on FNZAS :lol: :lol: Ceiling cavity doesn't sound bad, any space in the cupboards under the tank? Whats behind the curtains? If it's outside could you have it out there then pump it inside? How much beer is at stake?? :lol: :lol: Quote Link to comment Share on other sites More sharing options...

That's a window outside those curtains. I've thought about putting a barrel out there, but then I don't have a good way of getting a hose back into the tank. What I'm thinking of doing is I'll replace that shelf with a big cabinet and I can put a couple water containers in there. Quote Link to comment Share on other sites More sharing options...

Caper Posted October 28, 2005 Report Share Posted October 28, 2005 How much beer is at stake?? Hey Ira...you could be missing out here...offer a bit more than a beer, at least 2 :lol: ...and let them do the thinking and the work for you :lol: :lol: Quote Link to comment Share on other sites More sharing options...
HelifaxNZ Posted October 28, 2005 Author Report Share Posted October 28, 2005 So the concensus is to keep the lid off because of the heat issue more than anything else. Quote Link to comment Share on other sites More sharing options...
Ira Posted October 28, 2005 Report Share Posted October 28, 2005 OK, I'll offer a 6 pack. A whole bottle of bourbon if you provide the idea, parts and labor. Quote Link to comment Share on other sites More sharing options...
Gizzygirl Posted October 28, 2005 Report Share Posted October 28, 2005 Get a good size bucket or bin something to sit it on outside your window small airline tube with tap, top up your sump every 3 or 4 days.Just don`t forget to turn the tap off Quote Link to comment Share on other sites More sharing options...
Ira Posted October 28, 2005 Report Share Posted October 28, 2005 I have a 25L container for the topoff, gizzygirl topping off the tank run by a float valve in the pump section of the sump. When the topoff runs out I have maybe 6 hours before the water level in the pump section(the only part where the water level varies) drops enough to start putting bubbles into the tank. So, every 3-4 days isn't going to work. Actually, 3-4 days the pump would run dry. I think I'd have about...Hmmm, 1 and a half days before the pump runs dry. I based the sizing of the pump section on the evaporation of my previous tank which didn't have metal halides or an open top, sized it so I should hopefully have about 5 days before it runs dry...

Pies Posted October 28, 2005 Report Share Posted October 28, 2005 So the concensus is to keep the lid off because of the heat issue more than anything else. Light, then heat. ALSO there is kalkwasser, which is a very cheap way to add calcium to the tank and buffer PH. The more evap, the more top-off the more kalk can be added.

Then evaporation would be irrelevant. Quote Link to comment Share on other sites More sharing options...

How does running tank water through the kalk stirer make up for the fact the the specific gravity of the tank will continue rise as more and more 'h20' evaporates?

Ira Posted October 28, 2005 Report Share Posted October 28, 2005 It doesn't. It just eliminates the reliance on the volume of evaporated water for kalk dosage. You wouldn't totally get rid of the topoff, that would be stupid. You'd just run the kalk as a seperate system. Quote Link to comment Share on other sites More sharing options...
Pies Posted October 28, 2005 Report Share Posted October 28, 2005 No idea, maybee it would work? Pie Quote Link to comment Share on other sites More sharing options...
lduncan Posted October 28, 2005 Report Share Posted October 28, 2005 I don't think it would be as effective due to the common ion effect reducing the (already low) solubility of CaOH, so that virtually no additional calcium or alkalinity is added to the tank. It may also have the opposite effect, causing precipitation of CaCO3 from the tank water (depending on concentrations and pH).

Ira Posted October 28, 2005 Report Share Posted October 28, 2005 Shouldn't have any effect that dosing it with the topoff water wouldn't have. May be able to dissolve less per liter, but you could dose dozens of liters of kalk saturated saltwater compared to only a handful of liters of saturated freshwater.
