That's great, nice to know that others don't use pH+ when doing an AA

I use a large pond aerator I was just concerned that it wasn't ideal when doing an AA treatment

Hi I need to raise my pH after AA treatment I don't want to raise my TA as well Is it OK to just aerate ( which I normally do) to just raise pH My pH is quiet stable and doesn't require much adjustment

You are correct about the discolouration of the plastic and they weren't like that from new but I can remove the discolouration with my fingernail The failure is at the exact same spot on all of them, some have shown signs of being bent at the failure point but haven't failed yet All the...

That’s about right

Probably about 5 years I haven’t switched the MPV with the pump running There were more broken and bent laterals I was just concerned how the damage occurred

That wasn't the case as I had water in and the media went in slowly

The only problem I see is that you can suck in air

In the UK we get 14-15% sodium hypochlorite

Definitely a suction side air leak Check and lubricate your pump basket O ring, pump drain off plugs and inlet union There could be a leak between the pump and skimmer / main drain
