My first post...
Issue: My tank sounds like a waterpark in my living room/foyer - water rushing from the overflows/durso pipes and the air entrainment in the siphon PVC pipes that are under the tank and ultimately head to the basement sump.
I have a couple seasoned friends who have gotten me interested in salt tanks (I have has freshwater tanks for 20 years). I have worked on the siphon, return and closed loop pump pipes and pumps, drilled the tank, all ready for the water test...
I am similar in features to the basic setup of a friend's successful tank just on a modestly larger scale. I am about ready to throw in the towel though, but I wanted to cast my issues out to the collective knowledge here.
I have a 120 gal tank built in on the rear and one side in my foyer with a 75 gallon sump in the basement (about 11 feet of head). I am running a Panworld 200 pump for the return (may be one size too big, but it flows about 1250 GPH at the current head)
Anyhow I am struggling to get any semblance of quiteness out of the tank. I have twin "mega" overflows with the All-Glass kits durso-type siphons flowing through a 3/4" (or 1"?) bulkhead connector. They each have a ~1/4 hole in the top of them for the siphon break. The siphon lines upsize to an 1 1/2" pipe and then collect into a 2" pipe to head to the basement (I later added a valve at the basement in hopes of allowing more filling of the siphon)
Mods I have tried:
1. I put airline hose on the standpipes and that helped the gurgle and whistle sound somewhat
2. I have the standpipes adjusted to the top of the overflows
3. I removed most of the grates in the overflow
4. I have tried pinching off the siphon air holes to reduce the air entrainment, but then the siphon gets stronger as expected and I easily overcome the overflows and later break siphon
5. I have significantly reduced the pump output
6. I partially reduced the sump siphon downpipe in hopes of reducing its strong capability
I know you cannot run a full siphon out of the tank, but I cannot imagine people living with this sound (like a continuous toilet flush). I can attach a link to video or add pictures of the setup if you like.
I look forward to your help! (otherwise it is back to a freshwater canister filter and guppies! :roll: )
