First of all, I have no idea why I didn't get emails on all these responses!
Good news: The new DC4HD arrived today. Now that is seriously fast service from Neptune. Man that guy knows how to take care of customers!
Hop: Interesting idea. I'll have to think about that. It will make keeping the floor clean more difficult but there may be value in not getting electrocuted.
Marc: Good suggestions! Of course I don't keep anything electrical on the floor but unfortunately had some stuff temporarily down while I re-rigged some equipment.
My reactor is actually larger than the sump. I built it to sit on the rims. But I do have a plan to route the bottom flange so that water will spill into the sump instead of the floor. Tough lesson to learn but that's the way it goes.
Wow on that link! Has there been any determination as to why it got cloudy? Maybe from dying animals?
rdmpe: Always check in on my thread to see how disaster can strike!
Pic of my recent Vortech gasket mod:
Well, I believe it was Dave at IceCap that suggested I do this and it has taken a while to get around to it, but I do see quite an improvement. I hope this will help Eco-Tech in future designs.
As many of you know I have had a lot of problems with these pumps not the least of which is very high running temps. So high in fact, that my tank has crazed. What I have found is that the dry side magnet has been rubbing on the gasket and over-heating it to the point that it was getting deformed and transferring too much heat to the glass. This is in part due to my tank having 3/4" thick glass.
I took the standard gasket and cut out the center. This allows the motor to contact the tank properly but leaves space so there is no friction with the gasket. I used Super Glue Gel to glue it to the motor and got immediate results.
Not only is the pump operating at a normal temperature, it is also much easier to align because the gasket moves with the motor rather than staying in place and bunching up.
I will monitor this one for a few days and if it continues to operate this well, I will do all the others. I am really pleased with the results so far, and because it is easier to align, I don't have the rattling typical of when I remove and the wet frames for cleaning.
