Joshua J Denison

Hello,


I have been away and my Hot tub water is green. Will frog Maintain and a new frog Ease clean up the water

FROG Products

Hi there Joshua! The solution to green water depends on the cause of it. Check out our blog post on this very topic and detailed solutions: https://frog-old.local/blog/hot-tub/green-ht-water/

Tom Michels

I like this product and would like to buy more but no one has it in stock. Will it be available again? If so when?

FROG Products

Hi Tom! We are so sorry to hear it has been difficult to find FROG Maintain. Check out our selling partners on Amazon here: https://www.amazon.com/FROG-Maintain%C2%AE-Non-Chlorine-Shock-Treatment/dp/B0BF2ZFXWS/ref=sr_1_6?crid=23CJRS31YTFTY&dib=eyJ2IjoiMSJ9.LvbK2Y3FzSrQ480Ud1hrX_YI8lvI1on5SQW67sN3MqteiCSHVCcPSj32f1x-ARSN3du0xGvyfDZ-di6H3aHeAnL_JWXGmmSmECB3oo_5yBH0UKIPSCgEDzQhXHPE7iYGq2zfDZhrZsXLJJxV5xM1VOFXWbGJJitPrL5fi93VcmHf9BsZU-xF7_Ml1Up6XQ8jBR4DEZBaNEvYl-pJ2Ejl54lXE3rph6OEQ0llSEsa4n4.bWTweYHp1P-hXpOqTvSGnsr5hKfq_2yUXGJ55Dpcea0&dib_tag=se&keywords=frog+maintain&qid=1714486403&sprefix=frog+maintain%2Caps%2C90&sr=8-6

Nicole McClelland

I have had issues getting the water in my hot tub right since I bought it. I accidentally ordered this instead of the chlorine shock I was using. This stuff is great!!! I use this once a week and my hot tub water has never been more clear!

Deana Ruggiero

Why is this so expensive and it should come in a larger tub. It’s not that hard to measure it out. I wanna use your product but it’s so expensive to buy those packets. Please consider making a larger tub 🙂 we love our frog system.

Frank

Will the maintainer prevent brown scum? I'm using the @ease floating system.

FROG Products

Great question! FROG Maintain clears out contaminants like body oils, deodorants, and other organic contaminants that can result in scum if not treated. Usually, scum with a definitive color is a sign of other water balancing issues. In that case, a water test at your local dealer can be helpful for determining the water balancing issue.

John Dwyer

My Jacuzzi tub holds only 360 gallons, but your packets are designed for larger tubs. Do you have small quantity packs?

FROG Products

Great question John! Our FROG Maintain packets come in one size only to ensure that no one needs to measure or guess for periodic maintenance shocking. FROG Maintain is a non-chlorine shock, so it is safe and effective to use the packet for hot tubs of all gallon sizes up to 600 gallons.

Shauna Henry

Will the FROG Jump Start still be sold? It seems to not be in stock anywhere and where it is, the price is exoboritanty high. One place stated that Maintain is now being used in place of Jump Start. Is that true? If so, how do we get the right amount of chlorine in a newly filled hot tub. As it is now, my chlorine levels are always showing up low with use of the @ease system and the jump start. More information is needed please.
