PLEASE someone help me? I'm losing it. (Need pumps)
Go with the 3600, it's less that $200 online. I'm waiting for mine,
ordered it from pondliner.com. They were also the only place online I could find that had 2"x25' rolls of flexible PVC tubing which is all I needed.

It's a 2 speed pump (2400 gph and 5,000 gph) on 2.6 amps (low) for $199.95, including leaf trap. http://tinyurl.com/b3le Your limiting factor will be your piping: don't skimp if you want the maximum oomph from high speed. No less that 2", 3" would be better. Lee "Lisa" wrote in message om... Hi. I've spent 3 full days on this and still haven't made a decision so any advice would be SOOOOO appreciated. I want to build an approximately 1500 gallon pond (min. 1200). The pond is in a shaded area and at this time, I'm not interested in keeping koi. If I have any fish at all - perhaps some goldfish or native minnows. I want frogs. I also have a critter problem here and will have problems with keeping alot of plants. But I plan to have some. OK - My goal is to have a strong/loud waterfall spilling about 2' high from the pond surface. I want a biofilter in the waterfall head of about a 45 gallon size. My theory/desire is to have a nice roar/waterfall by day and be able to turn it down to basic "keep things alive/healthy" minimum levels by night/when away & not able to enjoy the pond. I thought of seeing if there was a variable or 2-speed pump for this, but the only one's I've found cost a fortune. So... I guess I'd like 2 pumps. One to run the biofilter 24/7, and one to turn on for drama to kick the waterfall into high gear when I'm outside/have guests, etc. I'm figureing this will save me a boat load of money over running a big pump 24/7 when I really don't need that. Since I want a strong/loud waterfall, I first thought of getting a total of 2400gph pump. Then someone suggested a 3600. I've been contemplating the pondmaster mag. The 3600 eats 380w. The 2400 eats 265w. 1800 145w, 1200 110w. I'm stil not quite sure how to calculate head, but I'm figuring the flexible hose between the pump & the wateroutlet/spill would be about 5-6 feet. So I know that a 2400gph pump won't REALLY be a 2400 when all is said & done. It would really be 1800. If I do the 2 pump deal.... How can I figure out the proper size to keep the pond healthy through the biofilter? I know you can't push too too much through the filter or it won't work right? So... Not only am I not sure if I need a total pump of 2400 or 3600. I'm unclear about the ratio I should split them up with. Say if I want 3600 total, should I get a 1200 for the biofilter and a 2400 for the waterfall drama? Or an 1800 + 1800? Or is 3600 total absolutely ridiculous? It's just that I saw the perfect waterfall at my local garden center and they had a 3,000 gph sump style pump running it. It looked perfect and I'd hate to have less than that look & am worried 2400gph worth of pump won't pull that off? This is such a nightmare for me. Hubby's out of town (he's the math expert of the house). My old preform is empty & ready to be ripped out. I have the liner and need to order the pumps ASAP cuz I can't stand looking at this anymore. So I'm anxious to place the order as my pumps might take at least a week to get here. What would you do? TIA |
