I'm new to the forum and want to thank all you guys for great job. I've read plenty about not pouring MA through your skimmer because of potential damage to your equipment but I can't find anything about pouring MA into a venturi skimmer using no suction only return.

ps. I can't pour in front of a return because the returns are the infloor pop ups.

The type of skimmer you have is fairly different than our normal suction skimmers. It creates suction by using return flow through the device to create a venturi effect and pull stuff into the skimmer basket.

The danger with pouring it into a normal suction side skimmer is that it will damage the equipment it travels through before it has time to dilute.

With your style skimmer using return flow only and no suction flow to create skimmer action, I see no harm in pouring the MA into the skimmer and letting it disperse it throughout the pool. It's actually probably better than pouring it in front of a regular return as it will get better mixing.
