Have to get humidity down: glass tops or canopy?

[hqgc]

I am getting mold in my finished basement and need to quickly get my humidity down.
My 180 evaporates around 5 gallons every three days.
I know a glass top would help , but would a canopy(without glass top) make a difference?

a canopy will help also ,if its sealed or tight if it gaps it wont do much good, if your not renting you can consider installing a airexchanger or simply buy a dehumidifier

I bought a dehumidifier off Kijiji for $150. It keeps humidity around 35%. Before the dehumidifier the house would usually be around 50%, but sometimes up to 65%. My 90 gallon tank evaporates about 15 gallons per week. Before the dehumidifer it evaporated about 10 gallons per week. Understandably, lower humidity in the house does make the tank evaporate more.

Pertaining to the original question though, glass tops work better than a canopy (unless canopy is well sealed), and have the benefits of keeping temperature lower since you can cover the tank with glass, and still have fans to blow the heat from the halides away. However, I wouldn't suggest you seal the top of your tank in any way if you don't have a sump, and especially if you don't use a skimmer.

If you do seal up your tank, keep an eye on your pH with a calibrated digital pH meter as it may fall due to CO2 buildup if the tank doesn't get enough fresh air. Check before sealing it up several times during several days, then do the same thing after. Record the time and the reading, and compare readings at the same time as pH will fluctuate during the day, but should follow a daily routine.

having a bathroom fan on will help or a fan venting to the outside-as for the mold-wash your walls with deluted bleach to kill the mold and it might be an idea to paint with a kitchen bathroom paint-or tint some kiltz

I think if water is condensing on/in the walls, then you do not have adequate insulation in those walls. As well, just for information, I have found a lot of places where the homeowner has done work him/herself and has not put the vapour barrier on the proper side. The vapour barrier always goes on the inside, the warm side. (in the winter.)

I guess the one downfall of glass tops is that you don't get the full benefit of your lights?

Doesnt a glass top hinder evaporation, which in turn leads to increased heat retention?

My experience with glass tops is significantly increased heat...?
