Dolphin T55i/30i/S300i

[Exlonghorn]

Looking to move from the CC Plus to the T55i. I’m attracted to the T55i brushes rotating 2X the speed of the drive treads as a way to brush off light algae growth. The CC brushes are more for locomotion than actual scrubbing. Any T55i owners have feedback on this?

Welcome to the forum!
Algae is a chemistry problem, not a cleaning or filtering problem.
I suggest you read ABC's of Pool Water Chemistry and consider reviewing the entire Pool School eBook.

Algae is also circulation problem

Algae is also circulation problem

Algae can be a circulation problem, but not always. Lack of circulation in an area of the pool can create a space where chlorine gets lower than it should and allow algae to grow in that area. We tend to find that this condition is rare, and as Marty said - for 99.99% or pools, algae is a chemistry problem.

Absolutely agreed. Latest tests using Taylor K-2006 kit...pH=7.3, TA=80, CYA=130, FC=8-ish
Need to get the CYA down before SLAMing so I'm working on that now (partial drain and refill). Pretty sure I had my automatic chlorinator set too high using Trichlor tabs (only had this pool for a few months so still trying to figure things out). As for the T55I, I'm just not a fan of brushing the sides of the pool (which I know will be less necessary once I get the chemistry straightened out) It's a pretty light algae problem, and I"m figuring that the high CYA levels are interfering with the sanitizers ability to do its job properly. The cartridge filters were just deep cleaned a couple weeks ago and I clean out the skimmer baskets every day or two (and they have pool filter socks in them as well) Any additional feedback is appreciated.

Start a thread in Algae Prevention and Treatment. You need to SLAM Process. You need a proper test kit for that, see Test Kits Compared. I suggest the TF100 from TFTestkits.net

As Marty said, we need test results we can trust and you need them to complete the SLAM you need.
Order a TF100 test kit.

The only other real option for a test kit is a Taylor K-2006-C. Be careful comparing prices because the K-2006 comes in sizes, designated by a letter. The basic K-2006 has .75oz bottles. You need to get the K-2006-C to get the larger bottles that you want. Even then it is a little short on the reagent & powder for the FAS/DPD test.

While entirely optional, I also have the SpeedStir and Sample Sizer. They speed testing and accuracy.

Thanks for the pointer on the K-2006-C. Since I'll need a new kit anyway, I'll get the larger test kit. The TF-100 is 1oz bottles for $70. The K-2006-C is 2oz bottles for $107. Seems like the Taylor kit is the more economical option?

To be honest, I get everything from TFTestkits.net mainly because they pay the bills here if donations come up short. While the forum is a
IRS 501 (c) (3) charity and accepts donations, sometimes they don't cover the bills

Good enough reason to me. Subscribed to PoolMath app as well. Happy to help those who are happy to help.
