will it empty a 300 gallon spa?

While I'm sure it would, I don't think that is the purpose for this pump. It is a condensate pump that takes out relatively small amounts of water generated by an air conditioner or a dehumidifier. I would consider a sump pump for emptying a spa.

No, this is not that type of pump. You will need a transfer pump with more hp than this one.

We have it installed to pump away condensation from large commercial a/c units. I'm no expert but I think it is too small to handle that much and would probably burn out fairly quickly. I'd go to a spa or pool store, find the right unit then shop for it online. The markup on these things is ridiculous.

Not sure how it works. But the spa started leaking again after three weeks. 6ft gunite spa losing 1" in 3 hours. Might work better on a smaller leak. Good luck!!

spa choice bromine works great and at a great price. I own a dynasty imperial 450 gal 3 pump tub good luck.

I do not know. I only use this and a mineral stick and my spa is crystal clear.

Not sure because I have a 500 gallon tub. I use one capful Of non-chlorine After each use or once a week. Try calling the manufacturer for an answer or your local hot tub specialist good luck

Not this model but the Blaster 3000 Automatic Pool and Spa Cartridge Filter Cleaner should be able to handle it.

It should. The bag is bigger than the flushable loo and folds down over the outside edge. Then the ziploc bag holds the whole thing when you're done. You need more chlorine granules than they provide in the bags. I just use the chlorine granules from my hot tub. It's a cool system!

Probably would damage the sand filter. I had to remove my cartridge filter before I poured this in my spa.

I have a pool with a spa with small waterfall, however I brought this product to get rid of small amounts of algie I never saw form. Just dont put right where water is running. I hope i helped also just start with small amounts. I used a forming one in another home and i hated it. I think this one is non foaming

Yes but you have to cut it to fit. You should be able a size closer to the size of the spa.

Hi Mary Lou, after installation, just add a little over a tablespoon of chlorine to activate Nature 2 about every 2-3 days depending on spa usage, and you're good to go! Also, I use test strips to gauge how often I need to add tablespoon of chlorine for correct alkalinity, ph etc. BTW, this is based on a 300 gallon spa, yours could be more or less... :)

I've had mixed instructions on that issue--yes and no. If used for hot tub, then no, just clean the filters; otherwise, daring and refilling is probably best. I was told to allow it to sit up for at least a week before refilling and allow the jets to run as much as reasonably possible. This stuff does work, although in my case the hot tub leak did stop but has started to leak even worse, not FIX A LEAK's fault. Bill Hilly

The filter is not going to be a problem. I have this on 9000 gal with 3/4 hp just make sure you leave filter on enough to filter whole pool. Figure gpm that pump does.

I have the Sundance Optima and I just use the Sun Purity that has a slot for it near the filter and AquaChek brand test strips that tests for monopersulfate which covers ph and alkalinity, the unit has an ionizer in it. I don't have info on the Marin spa

this is mainly for spas or small areas it only has a 2 inch nozzle so yes it will work but not for large areas. thanks

yes, you will need to empty but its well worth it. we emptied, cleaned it and re-filled it. keep in mind you will most likely have to prime the pump again or you will end up with air pockets in the line. if that happens, you can actually stick a hose into where the filter is and force water through. that will get the air bubbles out of the line as well. for a 200 gallon tub (we have a small one), we added 5 1/2 cups of salt. don't over salt. we also set our timer to 5 and it is working perfectly. the larger the tub, the higher the number so a 400 gallon hot tub should take about 8 to 10 hours per day. yes, you will need to empty but its well worth it. we emptied, cleaned it and re-filled it. keep in mind you will most likely have to prime the pump again or you will end up with air pockets in the line. if that happens, you can actually stick a hose into where the filter is and force water through. that will get the air bubbles out of the line as well. for a 200 gallon tub (we have a small one), we added 5 1/2 cups of salt. don't over salt. we also set our timer to 5 and it is working perfectly. the larger the tub, the higher the number so a 400 gallon hot tub should take about 8 to 10... » Read More yes, you will need to empty but its well worth it. we emptied, cleaned it and re-filled it. keep in mind you will most likely have to prime the pump again or you will end up with air pockets in the line. if that happens, you can actually stick a hose into where the filter is and force water through. that will get the air bubbles out of the line as well. for a 200 gallon tub (we have a small one), we added 5 1/2 cups of salt. don't over salt. we also set our timer to 5 and it is working perfectly. the larger the tub, the higher the number so a 400 gallon hot tub should take about 8 to 10 hours per day. « Show Less
