and there it is....the best of both worlds!!!I use a mesh from May through November and a glass lid from December on. Too much heat loss on top of the the evaporation if I leave the mesh on year round.
My glass lid has 1/4" spacing on each side and 1/2" spacing front and back, I like these tabs I found on Amazon that clip to the lid vs the tank which eliminates the salt creep buildup.
Sorry, yes, 20 gallons of RODI water. 20 gallons of DI resin would indeed be crazy20 gallons of rodi water I assume... 20 gallons of di resin is crazy... I use about 60 gallons of rodi water a week... which for me is about 1 cartridge fill (buy in bulk and refill).
Home Depot. Depending on tank size I buy 1 or 2 sheets, cut it with the diamond wheel glass cutter they sell, and pop it on the tank. If I'm feeling really fancy I take a file or dremel to the edges to polish them.Who sells glass tops?
Glass tops work as a great diffuser on puck leds.
My glass only reduces PAR by about 20. That's some thick glass you've got there!Lots of pros & cons listed here. I will share a number:
Slightly salty, 1/4 tempered glass lid reduces PAR by 125 to 150 directly under the lights. The further away from dead center, the greater the PAR loss. Just factor that into your decision making. I've not tested through acrylic yet.
Sort of, but ph is not related to oxygenWindows closed, CO2 goes up, O2 goes down, pH goes down. Open a window, O2 goes up, pH goes up.
If you are cutting evaporation in half, then you are probably cutting gas exchange in half as well. I don't worry about evaporation, since I have an ATO.Glass lids for life.
I see no reason to worry about gas exchange in a system with a skimmer and sump.
And I find the cleaning concerns are way overstated. I have to clean my tank glass every 2 to 3 d. My lids ... maybe once a month?
5 to 10% less PAR to cut evaporation at least in half... glass lids all the way for me.
Mesh lids for wrasses for sure... My Mesh lid saves a life of about 2-6 fish per day lol....
