Sorry it took so long for me to see this!

But, yes, I am familiar with it. And there are at least 2 solutions that work.
1) If you are using the FantaSea hoses that came with the system, standard hose clamps MAY work but it's tough to get in to tighten them AND keep them pushed snug against the underside of the panel. DeWalt makes a flexible nut-driver like this:

But I don't think that will work with the Fantasea hoses except where they connect to the return to the pool.

What will work with the FantaSea hoses is the following: you need two plastic clips per hose.

First, put a layer of Plumber's Dope, aka pipe joint compound either around the nipple on the panel or in the hose. Force the hose tight to the panel and put one the first clip, tight to the panel. You'll need a water pump pliers to squeeze it tight enough. Then put a second clip right against it, but with the clip going the opposite direction. This usually works.

2) You can replace the hoses with something like this, with the thick rubbery end, usually 3' length:

Then use a hose clamp and the pipe joint compound as described above. Use this kind of hose clamp:

I prefer the double clip solution for FantaSea hoses as it's inexpensive and works. In fact, if you complain loudly enough to PoolSupplies.com, who owns FantaSea, they may well send you the extra clips, all you need, for the good relations. That's what they did for me.

I only go to the second solution when a hose fails and I need a replacement NOW--and my local pool store has the hoses. I have a couple of those in my system and they are a permanent fix. The vast majority of my FantaSea hoses are still going strong as I disconnect key ones in the fall and blow them out with a shop vac. But EVERY FantaSea hose is double-clipped, with the joint compound. I get more leaks from the panels getting too much pressure. They are a high maintenance item.
