Most manufacturers suggest replacing the sand every 5yrs. when the corners wear off, the sand rounds and doesnt catch debris. it also packs faster.
if you are having short intervals between backwashing, it is a solid indication that sand needs replacing

Where do I begin when replacing sand filter with something great, very updated, but also user friendly & shiny & new. next what do i do about decor tiles falling off by handfuls daily?

Why replace a sand filter in first place. What is the last time you put a bag of sand avaluable at any pool dealer. I added a bag of approved filter sand and it was like I had a new sand filter.
You can also buy a bottle of sand filter cleaner. Put a bottle of it overnight with pool off overnite. Next day backwash and you will be amazed at green algae Walter coming out for first 30 seconds - then nice clear water!
As for why your tiles falling off, need more detaild

2hp Sand filter pump manual geting sand inside pool

The laterals inside the filter that hold the sand in and allow the water thru are failing and need to be replaced. For further assistance I'd need to know the brand and model of the filter. You may have some luck with a local pool store being able to help you once you have that information in hand. It is generally recommended that you replace the sand at the same time you replace the laterals since you need to get the sand out of the filter to change out the part anyway.

When I was filtering the pool the sand from the sand filter is blowing sand into the pool

That means that you have a cracked lateral in your pool filter. You will need to replace the lateral, which should stop the sand from entering your pool through the return line.

Sand Leaking From Filter into Pool. When my filter is running I am experiencing sand in the bottom of my pool from the filter. What can be causing that?

There is only one thing that can cause sand to come back into the pool from a sand filter. The internal assembly, called the lateral assembly, is either cracked or broken. This is an easy fix and should cost you around $70 to replace the whole thing. You need to unscrew the bottom drain cap on the filter to remove the water in the tank. Then, remove the multiport valve on top of the filter. Take a shop vac and remove the sand in the filter. If the sand hasn't been replaced in the last 3-5 years, this would be a great time to do that since you already have the sand out anyway. Then, remove the lateral assembly and inspect the entire thing. After you replace the lateral assembly, you'll need to fill the sand filter tank 1/2 full of water before adding fresh sand. This is done to cushion the laterals from the weight of the sand. Cover the hole in the top of the lateral assembly pipe with a cup or duct tape to prevent any sand from getting inside the pipe (the sand will come out into the pool if it gets into the pipe). Fill the tank 3/4 full of pool filter sand. Make sure it is genuine silica pool filter sand from a pool company. A lot of big box and home improvement stores sell play sand as filter sand. This will cause you more problems!

Water comeing out cloudy and makeing suds in pool

There could be a few things causing these problems. How old is the sand in the filter? Filter sand looses its filtering ability after 3-5 years and needs to be replaced. If the sand needs to be replaced, make sure you get actual pool filter sand. A lot of big box and home improvement stores sell play sand as filter sand. That will cause your pool to stay cloudy and never clear up. If the sand is less that 3-5 years old, you may need to clean it with a liquid filter cleaner that is poured through the skimmer. This works quite well!

Another issue causing the cloudiness and bubbles could be the type of chemicals you are using. I know that shock from big box and home improvement stores cause the water to be cloudy. Algaecides from these stores also cause foaming.

How do I put more media in my Hayward Sand Filter

To change the Media (sand, or zeolite sand replacement) you have to remove the top off the filter. There is a clamp that holds the top on. This is held together with two screws. If this is a top mount backwash valve you will have to remove the backwash valve. If you are lucky the person who installed it will have used unions so you can easily remove and replace it. If not you will have to cut pipes and re-plumb them when your done. If this is a side mount backwash valve then you should be just removing a top lid. Once you remove the top you can access the sand. You do not want to add sand without taking the old media out, and it doesn't do much good to replace only a portion of the sand. The label on the filter will tell you how much you need. Make sure you use #20 silica Pool Sand, and not any other type of sand. You can use Zeobest Zeolite sand replacement if you want a better filtration media. It cost a little more than twice the cost of sand, but you use half as much. It will filter better than cartridges, and almost as good as DE filters. You will want to "recharge" the media about once a year. this entails soaking the media in a solution overnight, then backwashing very well (another reason to use unions for the top). Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave good thumb rating if you found this helpful. Thanks, and good Luck!

Does the Hayward GM-245 Sand filter tank separate

I am not that familiar with the G series Hayward filters, but most sand filter tanks do not separate. It's a labor intensive job so think hard before trying it if you haven't before. If your backwash valve is on top of the filter, the plumbing will have to be removed. There are two ways that I have removed the sand. Scooping it out by hand or using a shop vac. Remember the sand is going to be very heavy when wet. You will need to go through the top. Some filters have a large drain plug in the bottom that "supposedly" you can drain the sand out through.I have done this once and it makes a big mess that you still need to clean up.

Be sure to buy replacement o-rings and gaskets as needed. There is also a product called a sand vac that is in essence a siphoning system.

Be careful not to damage the laterals it the bottom of the filter. When replacing the sand, I put small gravel (pea gravel) carefully under and partially around the laterals to help support them from the weight of the new sand.

When you are done, be sure to backwash the new sand to remove dirt, impurities, etc. This is a general overview. There are books online that give more detail or use a similar filter's manual...

I seem to have sand in my pool

If you are seeing sand in your pool, 2 things could be going on, first have you back washed filter, it could need cleaning, second you have a hole in one of the filter internal baffles letting sand in pool. I would backwash first, if still happens take filter apart clean everything, check baffles, if any holes replace them, fill with new sand, your filter cover has a tag on it and tells you how much sand you need. Then restart. You are done.

I need to change the lateral holder assembly and bottom screen on a Hayward S-200 sand filter. Will I need to remove the variflow valve or will it just come right out?

You will need to remove multiport valve and remove all the sand with a scoop. Not alot of fun. Think about replacing sand with ZeoBrite filter medium when you put it back together
