I've been using P D sand for the past 1 1/2 years in my sump and my main tank.There's no pollution or heavy metal detected.Try to collect the sand at BLUE LAGOON area during low tide.
There are few Islands that I know that are not packed with tourist and cheap.
1.Pemanggil Island(Johore)
2.Lang Tengah Island(Trengganu)
3.Pangkor Island Resort(Perak,very expensive but it is the best place for total relaxing like a KING)
4.Gems Island Resort(Trengganu)Private Island but affordable.
i have a 55 gallon reef tank mostly lps.it has been running for the past 7 months without any filter.i'm only using a 2012 weipro skimmer, 4 in dsb and around 40 to 50 kilo of live rock.but i have around 5 fish(1-3 in length) and the tank is full of LPS .nothing is dying or missing.i do change 25% of water once a month.
I only know the prices in KL for example
1.Weipro 2011-RM$100
2.Weipro 2012-RM$110
3.Cheapest live rock RM#4.50 a kilo
etc,etc,etc
but in Malaysia we don't have so much choice when it comes to marine equipment.
What is the best PH (L/HR) for a WEIPRO 2012?I've bought it last w'end for RM 100 and there's nothing in the collection cup.Water level is around 1/2 in before the collection cup.Right now I'm using a 1800 L/HR PH.
