    Skimmer/ bottom drain question

    I am building a small goldie watergarden around 1200 gallons. I know it isn't ideal but because of space issues I would like to try and run a bottom drain to my skimmer instead of a settlement tank. I have an Oase biosys skimmer. Would if be better to run the line into the side or the front? There isn't a lot of room underneath the rigid basket. Will it just gravity feed or can I use a submersible pump in the back? Thanks!

    I don't think it makes much difference. I would put it where ever it will fit the easiest. What brand of a skimmer is it?

    It is an oase biosys. Another option I am considering is running the bd to a skippy stock tank filter/waterfall but I'm not sure if the settlement can also be your filter? With my last pond I just had a settlement pond for plants and gravity flushed the pond during my weekly cleaning so I'm at a loss. I was always planning to dig a pit with settlement but ended up moving to a new house before having the chance. I don't have the room to do much of anything now because my pond is squeezed between deck, sidewalk and garage with trees next to it. I love the site but it is tight! I want a bottom drain because I have seen all the nasty stuff it pulls from the bottom but **** my life would be so much easier if I could just slap a liner down lol

    The Oase Biosys has a very efficient skimming weir door. Are planning on plumbing a retro-bottom drain or a regular bottom drain? If retro, it'd be just as easy coming thru the front. If a regular bottom drain, I'd plumb it thru the side.

    The trick however, is IDEALLY keeping it above the skimmer basket. The Oase Biosys' leaf basket = the entire footprint of the skimmer & you'll need room to pull it out for regular maintenance. There's some give to the box itself, but not if it's 100% back-filled & packed on both sides (right & left).

    Thank you that was very helpful! I was planning on doing a regular bottom drain. So the issue would being able to pull the basket up with the bulkhead and valve in the way. Hmmmmm..... Is there a skimmer that would work better? One that is good to use with a bottom drain? I would like to use this one since I already have it, got it cheap and seems like a good little skimmer for my size of pond. Otherwise I'm not sure what I'm going to do. I'll have to ponder this some more Thanks!

    The valve can be on the outside of the skimmer box ... hidden inside a rectangular or cylindrical irrigation valve box. Then it's just the flange from the bulkhead that may be slightly in the way.

    The Oase Biosys is an excellent unit because primarily because of the entry-weir-flap is amongst the most efficient for true skimming. 100% of the water enters over the weir edge & 0% seeps in thru the sides of the weir.

    There are many others skimmers that can be plumbed for a bottom drain but the issue falls back to % of water capable of passing thru the weir & % of water capable of passing thru the bottom drain.

    This is one that's handy in smaller pond applications for easy external pump connection as well as easy bottom drain port connection.

    Wow that was even more helpful! Is that an easy pro skimmer for external pumps?

    If you are planning to undertake any work related to drain then the best option you have is to look for the best in class service providers available to help you get the best with minimal cost and long term quality assurance. So, make a search about the drain service providers available online.

    I think a spam post made it past the moderators?
