I need some feedback as I put together my 75g. I have not used a top on my tanks in over 10 years. Consequently I have lost a few fish because of it. I like the open top look and function of my tanks. The only reason I am considering a glass top is I want to keep fish in my new tank from jumping out. Do you have any thoughts or opinions about using them? Any alternative options to using glass tops?

Not sure if it's "right" or "wrong" for any reason, but I have a hinged glass top on all of my tanks. Keeps the critters from escaping, lets in light and cuts down on evaporation.

I think they make mesh screens for aquariums too which help with gas exchange. I like glass tops because they stop stuff from jumping out and evaporation but they also stop dust from my room from getting into my tank.

I prefer to have them. In the winter, the dry air evaporates a lot of water off my tanks. I made custom DIY lids from Lowes for my 40b's (cheap 3mm glass, but it works). my 75g has the standard folding lids on it.

I use glass tops on all of my tanks. Every couple of weeks I clean them with CLR and rinse with hot water. I like them

I live in an area where it gets pretty cold and dry during the winter so I use them on most of my tanks to reduce evaporation loss. I'd prefer not to use them at all, but I choose glass tops over other options. They collect precipitate from the water and get dusty pretty quickly, blocking the light and looking dirty.

I've done it both ways. I prefer going topless. I like the easy access and the overall look. I also like floating plants which are hard to see with a top.

Hi @matt11390,

I think having or not having a glass lid is a personal choice. A clean glass cover (i.e. VersaTop) will reduce the light at the substrate level about 10% verses no cover. However, if you are looking at using an LED fixture on your 75 gallon unless you are going to suspend it will above the surface or purchase a fully sealed LED fixture (per IP67) you are going to want a glass cover because most LED fixtures fail for two reasons (undersized/poor quality power supply and moisture effecting LED's or circuit boards). I also recommend a LED fixture that has 120 degree lenses for better, more even spread of the light at the substrate level.
