Wondering if anyone has experience with the Pacific hydrostar pumps from Harbor freight.They say for clean water only.I want to apply these 1 or 2 to a system consisting of 30 gal. FT,30 gal sump and 2-15 gal GB containers, pumps are rated at 140 or 190 GPH and are .3 amps witch sounds very efficient as opposed to the 400 watt larger pumps they offer!...Thanks.....Bill |

I am using one right now in my 10 gal aquarium system. They work okay for the short term, but I wouldn't rely on one for all that long. Mine needs to be cleaned relatively frequently (about every 1-2 weeks), so keep access in mind when designing your system. Best piece of advice for this pump: buy a spare. Good luck! |

The only pumps I've had good luck with from harbor freight are the little (like 258 gallon per hour) One Stop Submersible garden pumps (I remove the foam filter.) Those ones have been doing fine for me. They are good enough to run a barrel ponics system. I have one in the indoor aquarium system and one is currently running my quarantine wing. They hook up to a 1/2" threaded fitting and have enough flow at about 4 to 5 foot of head to kick over a 3/4" loop siphon on a barrel cut round the middle grow bed just fine. I've also been using one to run my solar hot water heater and it is surviving so far even though I'm subjecting it to rather hot water daily. They run some where around 20 watts I think. The Harbor freight in our area has mostly the chicago electric pumps I think and the one of those I got didn't last long. It is important to buy pumps that have only plastic or stainless steel touching the system water since any other type of metal will corrode causing the pump to fail. If the metal is anything bad for fish, not only will the pump fail but it could also build up the toxic metals in the water and be bad for the fish. Also make sure any pump used is oil-less since the seals eventually leak and oil is bad for fish too. |

TC, How much was the pump you are using? They have sone 1/2 horse float types for $39.99 I wonder if they are usable or just go with the mini submersible types they offer. |

a half horse power pump would likely blow the water out of your little 30 gallon tank before you could turn around and turn it off. The little submersible garden pumps I got, I think I got them on sale for as little as $15 each but I suspect they are normally around $30. Are you planning on using a timer with your little system or using auto siphons? |

I would have to read up on auto-siphons, I thought that was shown in the CHIFT-PIST diagrams I looked at, maybe not though.I'm thinking I can't use a glass FT and run a typical SLO set-up, or am I wrong? What would you recommend, timer or auto siphon? |

If the pump is rated for continuous running... then auto-siphon... if not, timer... |

I'm running no holes overflows with SLO attachment on my glass aquariums however the no holes overflows can be problematic as they can get air in them and loose their prime and stop working. one of those little duckbill air check valves can be used to suck them out but those little check valves can fail too. So you can do it but they then require regular checking and I recommend extra redundancy if using no holes overflows. I would use at least two of them and check them often. Have a way to re-prime them. However, it is possible to drill holes in glass if you have the right tools. |

I guess the solution would be to use the glass tank for the sump and use a 30 gal. plastic vessel for fish with a typical SLO set-up.I still need to get components and some uni-seals.Thanks again! |
