I'd be very happy if my DC-1 was producing like Jonny's but after 6 weeks, still pulsing like an old steam engine. You can see it below the needle wheel and in the bubble column height at the cup. Sometimes, I can get the pulsing to subside for a while but it returns. Anything over level three. As I've posted before, it appears like a cavitation or as if the pump wants to pull more than the structure will allow, sucks more air than it can handle and ...burps? Cutting back air at the muffler can smooth it out, but skimming performance goes out the window. 6 weeks on and best I can get is tea. Hope parts arrive soon...this is hard on the reef and inmates.
Marc, is your skimmer sitting flat on the sump? Have you tried raising it somewhat, but ensuring there is enough space between the body and the floor?
It sits on egg crate fixed to a PVC stand. And, I've held it above the stand with no change to this condition. There is nothing inhibiting water flow into the venturi.
The original theory about break in for this condition was all wrong. I understand the issue related to "seasoning" the plastics and the implications to the bubble column being able to adhere waste particles, though I wonder if German made skimmers suffer even that problem. My US made skimmer was fully up to production in less than a week.
With this skimmer malfunctioning, I'm having to lean on carbon dosing and water changes to mitigate organics.
water level is measured where on the gate valve, middle, bottom or top ?
I have 10-1/2" of water in sump, so would I build a 4" stand? Put's the water in the middle of the gate valve?
need advice.... I have a 170 heavily stocked, with 60 gal sump...mixed reef...which one should I buy...
POV DC 2
OR
POV DC 3
Thanks
Dc2 it's performed well for everyone and performs above its spec in some regards . It's a great skimmer. The 3 is an unknown, could be the best. Uses the same pump but I'm not sure if the POV assembly is the same. It could be the best we just don't have many owner's sharing their experiences.
That's where ur decision is tight tho, I personally don vn't believe in "overskimming" I think the more organics, dyes and bs you can export do it. The whole foam head will collapse is negated by the DC uhigh water pressure column should presumably manifest burp-watery skimmate). Not one problem; skimmate level slowly rising every night or hospital visit never an overflow skimmer is just dead on. ~ 9-10". to each his own. Just feel bad for the DC1 issues.
I think it's time to go above " Jeremy " . My thoughts are, If I'm going to buy a " NEW"
skimmer for $550.00 and it doesn't perform , give me a refund, or replace the whole dam thing
Mine still, is all over the place. One minute's it's over flowing, next min it's not building enough head pressure to the 6" body
I have to set my alarm clock every night at 3am, to check it, cause I don't want it overflowing
Today for the first time, I'm getting a small amount of skimmed water filling it slowly
I was dumping it twice a day for the past 10 days
