Thanks for the reply. I can give it a shot, but I haven't been letting it get so out of hand that it has significant "volume" for me to scrape up. I don't know if it ever got that thick. It lives in between the pebble-tek surface.

I'm not certain it's black algae, but it looks much like the pics on this site: How To Remove Black Algae From Your Swimming Pool | Kill Black Algae For some reason that Pool School link doesn't go through. It just goes to the main blog page... And no, I don't have the TFP kit, but I think...

I think what I have is black algae. It appears as small black spots or dark black areas within the texture of the pool walls. I've been fighting it for over a year now. And despite fairly constant attention it has at times been very bad, appearing as large areas (many square feet) where the...

My Sand Shark stopped working. I have replaced it with a robot, but would like to get it functional if possible so I can sell it. The symptom is that it no longer moves, even with high suction. If I look under it while the pump is running, the thing that normally clicks back and forth is...

I thought I replied once but it didn't show up (strangely, I also saw an email notification of a response that didn't show up either). Anyway, I did decide to go with a robot. My pool is small, 8000 gallons. The main issue I had with the suction one was that the pump seemed to vary...

I know this topic has been covered a lot... I'm trying to decide whether to repair a broken sand shark suction cleaner, replace with another suction unit, or get a robot. My main gripe with the Sand Shark is that I'm constantly having to adjust the suction so it doesn't either sit still, or...

I'm interested in partially draining my pool a few times because CYA is off the charts. Being new to all this, I thought I could just use my regular pool pump to drop the level a few feet, then refill it. This is an in ground pebble tec pool. When the water level got to the skimmer level, I...

Worked! Plugged the crawler into the vac port and adjusted the selector valve at the pump to direct most to the vac port but enough to the skimmer to reduce the suction to the right level. Both the skimmer and crawler can work at the same time now. Thanks.

Interesting. I'll see if mine can be part way on each. That would be ideal.

The vac ports look exactly like eyeball diverters. I unscrewed an eyeball and put on the door that came with the crawler. I guess my main limitation is that at the pump I have to throw the valve to either vacuum OR skimmer mode. I can't have both at once. The user manual expects the option...

The thing I have to plug in to the skimmer is way too big to allow the basket to go back on. I tried to install into the vac port last night but it has way too much suction and I have no way to reduce it. It seems to work okay plugged into the skimmer, but it is annoying that the skimmer is of...

Just bought a crawler for our new pool and the instructions for install don't seem to line up with what we have. We have two suction ports on the side of the pool. There is a manual valve that selects between the skimmer/drain and the two ports. I was hoping to attach the crawler to a suction...
