Was considering switching from gravel to sand. So I need to know if this is alright with two external filters in my set up. Worried that the sand might clog them up.
 
We use crushed coral in all of our tanks along with some decorative natural rock. As long as you keep the intakes from the power filters 4" to 5" above the level of the sand you should be OK.
 
Also the finer the sand the more likely it will get in the filters... agaronite is better good and I hear pool filter sand works well.. I use play sand but I have not had a problem with my hang on the back filters...
 
Thanks... Figured it would proabley be alright. As you'll said if I don't use sand thats to fine and keep my filter intakes up. Planning of swapping out my current cheesy blue,red gravel combo.:screwy: To black and natural colored sand combo. To match my background. Just need to find some black sand.

I have had sand get in to my filters, but it just sits in the bottom. As long as you have a layer of filter wool in your filter sand should never reach the impeller motor if some does get sucked up.
 
tahitian moon sand is black most lfs have or can get from drfostersmith.com what kind of filters are we talking about here canisters I don't see any problem hot like ac110 etc after the water comes up the tube it goes right to the impellar so could be a big problem.... if you went to your local contruction yard and looked at yellow or brown concrete sand they would be ideal they are normally to course to float in the water column... I used brown for awhile then switched to bare bottom
 
I have a 100g with a sandy bottom (sounds kind of hot)...... 2 canister filters have no problems with it. Intakes are maybe 2 inches off substrate and directly over sand. Maybe 1 Tbsp. of sand per canister. No probs

With a canister filter, I agree here, but with HOB's, the the impeller is the first point of entry to the filter.
You could try "panty hose" or something similar (I use sponges) on the intake tube(s) which helps, but will need frequent cleaning.
In most canisters, the pump is the last point before returning to the tank, so the poly wool does work.
 
I have sand in both of my tanks and use an XP3 on both. I also use pool filter sand and stir it up when I clean it. Even if a little bit gets in the filter, the impeller is on the out take side, not the intake so the sand never even gets to the impeller. I only get a little bit of sand in my canisters
