Are two filters better than one?

One thing you can do also, when you vacuum, set the valve to waste. You do not need to be running that sediment back through a filter that does not work right. AT least with the vacuuming to waste, you are eliminating the stuff that settles

I used the vacuum to waste method, and felt that I was really losing a lot of water. I didn't think that I could get all of the "dust" out without going below my skimmer. I usually have the water level above the skimmer opening, too!

I'm not sure what could be wrong with the filter/pump in order to check things??? Any ideas?

I guess I will get to inspecting the pool sand filter next weekend. Just finished laying 14 palettes of sod. I was afraid there may be something wrong with the filter but i guess i'm trying to check everything else prior to tearing it down.

When i vacuum the silt, the water from the return is cloudy. When the filter is running (not vacuuming the bottom), the return water looks fine. Thats why i thought the silt was so fine that the sand couldn't contain it. Hopefully I will find out next weekend if i'm off. The water chemistry is good, and the water is clear, with the exception of grass clippings from mowing and the silt at the bottom.

Thanks for ya'lls help. Yes i'm from Texas.

Vaccum to waste so that it doesn't come back into the pool.

ummm I was wondering how this all turned out as I have the exact same problem with silt and fine dust coming back through the return jet when I vacuum. I am troubleshooting in another area of the forum but thought a reply here might yield a response from the person who started this thread.

I have same problem, but think it's from the street that runs parallel to my pool. It's about 15' from pool and separated by an 8' wooden fence. Problem is that it's a low spot where creek run goes behind my property and then under streets. Two streets actually, since it's a divided street and speed limit is 30. I think this because it collects on the coping--above ground pool.
Anyway, I'll try the DE thing, just to get better filtration. Also wondering how poolboy was doing w/ his problem.

Heres your two options that I know Of.

1. replace your sand with Zeobrite. Filters down to 1 Micron

2. Kind of a stupid looking product but it does work "Slime Bag"

Good luck

Even DE ONLY filters to abut 5 or 6 microns. The claims for zeolite are based on the 'pores' in the grains. However, the grains are about the same size as a sand grain and water is going to take the path of least resistance so most of the filtering will take place BETWEEN the grains, just like with sand. The filtering ability is only slightly better. It is good at ammonia scavaging, however, so it might help prevent the formation of CC. Zeolite is the new "craze" in the pool industry but it has been used in aquariums (primarily for it's ammonia scavaging properties and not for mechanical filtration) for many years now. As a mechanical filter is has proved to be not much better than sand. The "Slime Bag" is a micron filter bag. Once again these have been used in aquariums for quite some time now. They do work but have to be changed frequently and can create some (or quite a bit!) backpressure in a pressurized system. In aquariums micron bags are ususally used in non pressurized 'wet/dry' or sump filters with a low flow rate.

ok, I've noticed that the all around answer to this topic hasn't been answered, atleast not that I have seen . Does a "Duel" Filter system work or not? I.E. A Pool->Sand->Cartridge->Pool set up with a bypass between the Sand and Cartridge connection so its Pool->Sand->Pool. Right now I have a Cyclone 200 Cartrage with a 1.5 HP Dual Speed Pump (and to me, its a *****). I have been thinking about getting a BaquaPure 2600 Sand Filter System and start using Baquacil.

Keslongwood,

The answer seems pretty clear to me. Two filters ARE better than one. In fact, three filters are better than two. Come to think of it, four would be even better. Start with sand, then into a cartridge and then into a DE.

It can be as complex as you like but, simply, more filtration will result in cleaner water. Would I ever do it? Of course not. My pool is crystal clear with a sand filter.

As an aside, I noticed the filtration at one of those huge Ripley's aquariums is sand....I think they had three set up in series.

Now, the real point of my post. I would suggest reading on this forum the experiences people have had with baquacil. You may very well rethink baquacil as your sanitizer. I'm pretty sure others will opine soon....even tho we're sorta' hijacking the thread.

Using Baquacil is still in the air, I am however trying to get the filter for it, BaquaPure 2600 Sand Filter. Its basicly just like every other sand filter, cept its blue, and I like blue ^ ^. I did to a thread asking on where I can find one.
