I believe it's calcium built up in my tank and hood, it's a white color and tan color. What's the best way to clean this off? Tank is fully drained yo thoroughly clean it.
Also what's best way to prevent this from happening besides getting a RO unit?
Yep, vinegar works pretty well. I recommend using the cheap distilled ones. Those are good enough.
To prevent calcium deposits in the tank, just make sure you top the tank off a lot.. make sure to refill the tank when there's a lot of evaporation and also checking the water level doesn't get too low too often.
Will be doing this tomorrow. I wish there was a way calcium deposits could be eliminated by something being used in filters! Might need to invest in a auto top off to help...
Could I use 0000 steel wool on the glass with the vinegar? I'm using a blade and while I got most of there is still this haze that is not going away with the blade.
I wouldn't recommend using anything metal to scrub down your glass tank regularly. Even a razor blade without applying pressure scratches up the glass - eventually those scratches build up.
I use CLR for calcium deposits. My tap water (well water) has a pH of 8.3 to 8.5. Needless to say, I can run into some major calcium deposits. And I don't have the patience for vinegar. I've never had any issues with using CLR. It is important to rinse well, of course.
And I suspect the prevention is RO/DI water. Avoiding air stones or any source of bubbles helps minimize the buildup around the hood/lid area.
If you keep the tank water level up that becomes less of an issue but still needs maintenance on hoods etc. You need to find a schedule of scrubbing that works for you: razor blades or nylon, neither is a cure-all...I'd be willing to put up with once/month hood/water level deposits at most...but that's me & my laziness. How much does it bother you?
