This rotary feeder has solved my problem. Contrary to the installation instructions I have not integrated after the sand filter in the pool running, but simply equal to the drain. So I do not lose the flocculation of Multitabs and it is in principle nothing more than would admit the tablets in the skimmer, just with the ability to adjust the dosage.
I have a Intex Quadra II, which has a shut-off valve at the outlet. Then come ca 3 meter hose, the rotary feeder and then a check valve because my sand filter is above the garage. So I had only 2 sockets with 1 1/2 inch thread and 38er hose connection to order and had for nearly 20, - a super functioning dosing. Those who can not shut off before and / or behind the lock circulation, needs a stopcock for about 10, -
After installation I set the metering position to the 1/4, now it stands at a filling 3 of Multitabs per 200g between 1/8 and 1/4 and I have, at present open pool a constant value of 0.3 , If the pool extended period is covered with a solar film, the position reaches 1/8.
But on what you have to pay attention: When filling only the shut-off valve supply by the end and turn up the bleeder valve on top of the dispenser and hold your breath or take cover. The chlorine vapors that are discharged as formidable. But one sniffs only once, then you know it ... then unscrew the cover, Multitabs pure turn. Open water circuit, switch the pump and sit back. Despite new tabs, which dissolve slightly faster usually at the beginning, fits the chlorine value. The investment total pressure was not changed by the installation and everything runs fine. As I said: The installation into the end of the pool is not a problem, on the contrary.
I actually did not expect much for the money, so was very surprised at how well the lock works. I would buy them again at any time and it can only recommend. It saves chemicals and once it has been adjusted to the needs, you can also save the daily shows.
