Question Surface bubbles accumulating

We have a 36 gallon bow front tank with a bubble bar in the back. Lately the bubbles, when they all reach the surface, aren't popping. They accumulate in large groups. If I drop fish food on/in them then the bubbles start popping & most will disappear. If I stick my fingertips in the mass then they will also start popping & disappear. If I stick my metal tweezers in them nothing happens.

For filtration we have a canister that expels through spray bars. We also have a HOB. This tank has a pretty strong current and is pretty well planted. No co2. I fertilize randomly, iron & a general liquid fert (don't know the name atm because I'm not there).

Why are the bubbles sticking around, now? We've had this same setup for quite some time and this has never happened before. The only changes are that I have transitioned from plastic to live plants, and thus also the random fertilization. I'm hoping that someone here can shed some light on this for me.

Several report that this happens. Some call it "protein buildup". There are often suggestions that more surface movement will cure it but in my case, it did not and only created a bubble pile. For me the end solution was a surface skimmer. About a ten dollar item which connects to the intake of the canister and has a floating head on it to collect surface water. I found it very worthwhile.
