Welcome to TFP!
The main problem is your Cyanuric Acid (CYA) is too high so with your low Free Chlorine (FC), algae is able to grow faster than chlorine can kill it and that is clouding the pool. Your pH is too low as well so I suspect between the high CYA and low pH that you have been using Trichlor pucks/tabs. These lower the pH and TA and increase the CYA over time.
I suggest you start by doing a partial drain/refill to lower your CYA level. Start with at least a half drain/refill. While that is going on, get yourself a proper test kit, the
TFTestkits TF-100 or the
Taylor K-2006 where the former had more volume of reagents you use the most (see also
Test Kits Compared). You could also add either some pH Up (if you already have it) or 20 Mule Team Borax to the pool to raise the pH at least to 7.0 but not more than 7.2 for now (it may change when you do the partial drain/refill of water and you'll want it lower when you start the shock process).
I'd stop using the Trichlor pucks/tabs and add some chlorinating liquid or bleach to raise the FC level to at least slow down the algae growth while you are doing the partial drain/refill. Get it up to at least 10 ppm -- that's no where near shock level, but it should take the edge off the algae growth since apparently it didn't get started until the CYA level got this high. This is just until you replace water to get the CYA lower. At that point, you'll shock the pool as described below.
Also while you are waiting for your test kit and are doing a partial drain/refill of your pool, you can start reading the
Pool School. When your CYA gets lower, you'll shock the pool with chlorinating liquid or bleach to kill off the algae. This is described in the Pool School articles
Defeating Algae and
The Shock Process.
If the numbers you reported were from the pool store and not your own test kit (those numbers look like pool store numbers), then you could wait for your test kit to verify the high CYA, but I suspect it is indeed high.
