Is this a symptom of a faulty air relief valve, and if so, would this be a cause of high pressure?
air relief slowly dripping water once pressure rises.

Welcome to TFP!!!Your signature is blank so I have no idea what filter you might be talking about.
Is the drip from the air relief valve itself or what that attaches to the filter body?
How much is your pressure rising? We recommend cleaning when it goes up 20-25% over the clean pressure.
Looks like the water is dripping from the actual air relief vale spout, causing me to believe that maybe it's damaged and not air-tight. I put a new gauge on it and made sure there was plenty of teflon tape , making it snug and tight. The air relief valve is a pentair ( here is a link to what it looks like https://sunplay.com/products/pentair-air-relief-valve-98209800?variant=6881570357283&gclid=Cj0KCQjw_ZrXBRDXARIsAA8KauSQKJUWfjFnKBkXm2nd-CUikP7A-DDvGqDKBRRFB3KX_MitSCL5QQ0aAiaMEALw_wcB )
This is an American Products Titan vertial d.e filter, by the way. When I start it fresh, the pressure is around 15/16psi. But literally not even 20-30mins later it will have jumped up to almost 30psi. I have tried pinpointing any air leaks and have found none. Just wondering if a faulty air relief could cause the psi to jump .

I discovered that mine drips a bit too when the pressure gets very high.
Your bigger issue is the algae in the water. You need to get it killed before you start to try to filter it out. Do you have a recirculate mode on your backwash valve?
You need one of the recommended test kits and to follow the SLAM Process.

Ok thank you. So , when I am killing off the algee, should I NOT be running my filter/pump?
It depends on your setup. You need to be circulating and mixing the chlorine in the water and brushing. But, if your filter clogs up too fast then you need to get around that problem.
How big is your pool? Add it to signature. You have a pretty small DE filter.

a lap pool , 7.5x42 .. average depth is 5ft. So should be right around 12,000 gallons
So your filter is reasonably sized for the pool volume ... when the water is clear 
Now that it is green, you will have your work cut out for you cleaning it up as the filter will clog very fast.
If you do not have a multi-port valve with recirculate option, I might suggest removing the DE grids and running the pump in that configuration until you have all the algae dead, and then filtering everything out.

Gotcha. Thank you for the very helpful advice.
So I should just remove the entire manifold and then put the lid back on as it usually is [assembeled]? That will keep the circulation going through the pool without clogging the filter grids, and then I can continue to kill the algee. Once the algee has been killed off, put the manifold/grids back on/in and run as normal to filter out the dead stuff? Just want to make sure i am correct. Because, no I don't have a multiport valve unfortunately.

Yes, that is exactly what I was suggesting.
You did not mention any other equipment between your filter and the pool (like heater or SWG or solar), so nothing should get clogged with debris. If you DO have any of those, then this may not be a good idea.

No the only other thing I have between the filter and the pool is a valve that allows me to open or close certain jets leading into the pool. There are 3 on the side of the pool, and 2 at the end, so that valve lets me run the sides, the end, or both ( if I choose ).
Thank you so much for your help. It means a lot. I will update my signature as well, sorry I am new to this site and had no clue what I was doing. Haha. - Benny 
Could be an o-ring too. I've had my plastic air relief valve leak because of a shrunken o ring. Lube the o ring with clear silicone lube.
