we keep flocking our inground pool but it still keeps getting green. I'm thinking the sand needs to be changed in the filter but don't have a clue where to start. Any help at this time would be great.

The sand in pool filters typically needs to be changed every five years on average. The cause of your water turning green is probably not directly related to the condition of your sand. To prevent the water from algae blooms it is important to maintain the proper level of chlorine in the pool. Another factor to consider is the level of phosphates in the water. Phosphates are food for algae. A pool with high levels of phosphates (1000ppb or more) will turn green very quickly when the sanitizer levels are allowed to drop because the conditions are great for algae growth. To reduce the phophate level visit a professional pool store and inquire about Natural Chemistry products or something comparable. I agree that the use of the proper type of sand is essential. It is also important to run your pump enough for proper circulation and filtration. To clear a cloudy pool the pump may need to run continuously until clear. With proper water chemistry and filtration you will find your pool easy to maintain.
I hope this helps...

Remove the top from the sand tank. Note the level of the sand because you don't fill the filter tank to the top. Remember this is how high you will put replacement sand.
With a plastic cup dig out the old sand. When you get near the bottom you will find the plastic spiders that are like spokes attached to the center tube. Be careful not to damage the spokes. That is as far down as you have to go. The sand left in the bottom two or three inches can remain.
Be sure to buy pool filter sand. It is a special grit. Get it at a pool supply store. Don't take a chance - get the right sand or you will do this job again.
Put new sand to the level noted above and replace the filter top.
It isn't as hard as it sounds.

Is it getting green from improper chemistry? Changing the sand won't help this condition. Is it getting green from not being circulated long enough? Again, changing the sand won't help. If all the above is correct then by all means change the sand. Remove the filter top. Scoop out the old sand and replace with new. It isn't a hard job, but it's messy. Add water to the filter tank before pouring in the new sand to prevent damage to the laterals. The filter label should tell you how much sand is needed. Good luck.

Does your sand filter installation have a back-flushing function? If yes, do that first before changing all the sand. Back-flushing reverses the flow through the filter, and spews-out all the dirt and solids through a separate hose.
