I think you're wasting your time, coming onto the forum, since you really aren't taking our advice.

I've often noted over the years that pools aren't that hard, but they aren't forgiving, either. That's doubly true of Intex pools. Their filters are just barely big enough to manage if you do everything right. Once something has gone wrong, clearing the water again tends to take weeks, not days.

You don't probably don't need the polyquat. You don't need an algaecide. (Chlorine is the best algaecide.) If you have the Robelle pH Rise (washing soda, available in the Walmart detergent section for 1/2 to 1/3 the price), you don't need the borax. It's just a better way to raise the pH, but washing soda will work.

You DO need a reliable way to test, which you don't have. The SSR handles CYA levels for about 2 months by 'dead reckoning', but you're probably too late for that. So you need some form of the Taylor CYA test.

I understand the whole, "I already blew my budget" thing. But the problem is, a single episode of algae can cost as much as a month of normal pool care. The algae could care less what your budget is -- it just wants to grow, and will do so if your chlorine gets low. It sounds like your chlorine has been low. Pseudomonas is possible, if not entirely likely, in a pool that's operated for 3 weeks with intermittently low chlorine. If you DO have Pseudomonas, to get rid of it, you need SUSTAINED high levels of chlorine. It's capable of growing when the chlorine is low, and protecting itself with slime when it's high. (Mustard algae does the same.)

FWIW, if you're trying to diagnose yourself, Psuedomonas characteristically is more likely to appear in areas (a) covered by a swimsuit (trapping the bacteria against the skin) and/or (b) areas exposed to pressurized flow for a period of time. But that's not an absolute thing.

Good luck!
