kaosu... I take the pinto filtration comment back... your tanks are beautiful... lol im glad we have the same filters![]()
wow... we literally have the same equipment... is that the penguin bio wheel 200... You really have a gift for aqua scaping.... I think your glass is a little thicker... Probably bullet proof... I am not using mine atm It holds water but I need to re-caulk it, 21 years old... better safe than sorry. Is there a tag on that tank with date?
you know... your right... it should be fine on the orginal caulk. 500GPH!!?!?!?!? over achiver! well it must be working cuz the fish look great! ever try adding plants into the HOB?
Also I have built up white residue on my filter and since I have been posting about them, I think its time for an overhaul.

How Do I remove this... Sad to say but I even resorted to chemicals, soaking, super hot water. Im totally dumb founded


I have 2 of those filters. They still work perfectly after 20+ years of continuous use.
I may have had to replace the impeller on one, but that is about it.
This is the media I use for them--available pretty much anywhere and is completely unchanged since they came out. The only change is the internal plastic frame. It is more sturdy now and does not bow like they used to.

The white residue is normal. I always get it on those, but we have hard water here. I can usually just flake it off. Otherwise, good vinegar works.
