Thanks. I haven't been able to aim the PH
to the surface, and I noticed the air bubbles agitated the surface. I suppose I could just use a 45 degree elbow fitting. But for now I am going to use this setup as a wavemaker:
While I'm on the PVC
subject, is PVC
cement really safe in SW
? I found <<these>>
I ended up with a different product from the same company when I went shopping at Lowes this morning, "Medium Lo-V.O.C. clear cement". I emailed them, but based on my email experience with the lava rock(still haven't heard back...) I doubt I'll get a response. Any one have any insight to the difference/safeness of the stuff they sell in the pet stores to "Medium Lo-V.O.C. clear cement". On the label is says reduced solvent emissions.
Edit: I just read on my cement it says schedule 40 & 80 for potable water. So I guess the real question is what do these schedules have to say about the issue...
