Simply Koi and More Koi

Hi all, Me again. I'm having problems choosing a suitable sealant to secure bottom drain to QT and for connecting solvent weld pipework, that is fish friendly. There seems to be a fair few out there, but do I need a certain type for the drain, and a certain type for the pipework or is there a sealan...

Hi,

Has anyone got one of these air pumps, or similar?

I'm trying to work out if they are particularly noisy to run compared to the Hailea diaphragm models.

Also, if anyone has got one of these types, are they any good?!

Thanks

Dave

Cheers Jules.

Also, how would you connect a grundfos 15-50 heating pump to the pressure pipe?

Is there certain connectors needed and is it easy enough?

Thanks
Dave

Hi all, I was just wondering whether there is any particular type of pipework you use when making a Q/T. I'm looking at 2" plastic but is it just standard waste pipe from a plumbing merchant or a special kind? Also, where do you get the shut off valves and things for the particular pipe. Cheers...
