Sand and Tunze?

[siskiou]

I put the sand in last night, and this morning the Tunze flow bouncing off the mid front of the tank had dug a nice whole and left the rock lifts there totally exposed.

 

How do all you owners of tanks with sand and a strong pump deal with the blowing sand?

Are there better ways to direct the Tunze output?

 

Mine is in the left back corner, about 7 inches down from the top, pointing diagonally to mid front of the tank.

Should I bring it up higher?

Hang it on the side and have it point toward the opposite side?

 

When I had no sand, the pump never seemed quite as strong!

Its all about positioning. Just gonna have to mess with its position and direction and maybe add some rock in spots its too strong to defuse the flow.

i mix in some coarse sand, it helps keep the finer stuff in place, about 1 part coarse to 2-3 parts fine stuff, and where it does dig the rough stuff stays so it keeps it from diggin holes that are more than half an inch to an inch

If you're using sugarfine like my silica sand...good luck. My unmodded MJ1200's have to point at middle of glass or higher to keep sand from blowing around in piles. My solution is to suck out a little sand with each water change and eventually put something heavier in its place down the road. I have some "t"'s connected to mine with hose out each end so I can direct the flow easier.
