A new 12" or third 9" Matala rubber membrane disc? - 09/24/19 08:00 PM
Hi all!
Been way too long since I've checked into this forum.
To keep the math very simple and quick, I have a 100' x 50' x '6 little pond, COMPLETELY COVERED with thick FA. I have two Danner air pumps, one AP-60 (3.18cfm) going to a single Matala 9" rubber membrane disc diffuser (with weighted base – handles 1.4 – 4.2cfm) about 25' from pump, and a Danner AP-100 (5.29cfm) going to a second of the exact same diffuser setup at the other end of the pond, approximately 80’ away from pump.
My questions are:
1. Will the AP-100 damage the 9” disc by pushing too much air to it? Is there any loss of cfm given the distance?
2. What is more effective, one more 9” diffuser, totaling THREE diffusers for this size pond, or replace the farthest 9” with a 12” and only have TWO total diffusers in this little pond?
Three diffusers would be: Two 9” on the same air hose from the AP-100 pump, one at 25’, one at 80’. This would presumably provide only approximately 2.65cfm to each 9” diffuser – all things being equal. That in addition to the AP-60 pump satisfactorily pushing out to a 9” Matala diffuser only about 25-30’ from the pump.
3. If anyone has any suggestions on how to improve the condition of this body of water, I’m all ears. It is NOT downstream of any fertilizer-laden farm fields or anything of the sort. There is perhaps at least one foot deep of muck on the bottom.
*The “flow-through” of this pond seems as rather fast in my ignorant opinion. There are so many springs feeding this pond, I have yet to calculate the outflow, as it’s not as easy as putting a bucket beneath the drain. There are springs joining the same pipe below the pond before the outlet as well. It has one 4” drain pipe.
Oh, also on a related note of FA abatement, mid-June I put in a whole bottle of black pond dye (rated as one bottle for 1 ACRE, where this pond is 0.11 surface acre), and it flowed out and completely disappeared in about a month or less.
I eagerly await a helpful response, as I’ll wait to order anything until I learn what is the best-case scenario for me to implement. Please feel free to correct any math errors.
A HUGE thanks and appreciation in advance for any help.
Chuck
