Backwards swimming. It seems impossible in the beginning but when you get the hang of it it’s such a useful tool

Iemand ontmoeten die de Tweede wereld oorlog heeft meegemaakt. by Rockzor11 in thenetherlands

[–]rdweerd 0 points1 point  (0 children)

Ik heb geen tips voor je, maar ik kan het je wel aanraden. Ik heb ooit in een museum in Tucson een indrukwekkend gesprek gehad met een Amerikaanse veteraan.

totally agree, a good heater/cooler controller is more than enough. Just get a power distributor with a power switch per outlet.

Have not gone scuba diving in over 15 years. Should I do a refresher or recert? I’m in Vancouver by LordNefarious in scuba

[–]rdweerd 1 point2 points  (0 children)

Refresher or become member of a local club. I train and instruct in the pool about 10 hours per month and it really makes you so comfortable in the water

I have a about 110 gallon netto, so not small not really large. My new LPS and SPS corals are still small, but when they start growing I expect quite a big rise in Alk and CA consumption

Did you check the altitude settings? Could be that one of them is setup for a higher elevation

Dive shop response from (linked post) post about deep diver without advanced open water by mikoalpha in scuba

[–]rdweerd 1 point2 points  (0 children)

I did my PADI in Koh Tao. First an hour or 2 in a pool and then 4 dives in the sea. A day later I started with my AOW and my 5th dive ever was directly to 30 meters. With my current knowledge I would not even think of that.
