Taga-asa ka sa Cebu? (cebu pud ko ^ ^)
Anyway to answer your questions:
1. 10 gallon aquarium with sump
- will internal(built-in) sump do or is separate better?
Internal is fine if that's what your tank has already. I only even have a crappy canister filter. If you plan to use a skimmer, something to consider would be the size of the chamber in your internal sump. You will need to find a good nano sized skimmer that would fit in it.
2. Protein skimmer
- what are some good quality protein skimmer?
Go for the name brands (Reef octopus). I bought a resun skimmer and it was -meh-. You need a good skimmer if you plan to keep sps, but for softies and easier to keep LPS you can go skimmerless.
3. Pump
- how many do i need?
I have one koralia nano (you can buy this at Piper's). But how many will depend on your livestock (what corals are you planning to keep?). Try one k-nano, and if it's too gentle for you you can add another one.
I'm assuming your built in sump has a pump too? If not, you will need a small pump for your built in sump's return.
4. Powerhead
- do i need one?
I am assuming this is for flow reasons? Answer in #3
5. Heater
- is it still needed?
Nope. Chiller might be needed though if you plan to keep SPS. I have a fan for my bulbs and partly for the tank.
6. Lighting
- i plan to have LED, any recommendation?
PAR38 bulb from sir peter.
7. Test kit, hydrometer, live rock, live sand
-Anything else i still lack?
You lack tank build pics.
What media are you using in your sump? (I'm assuming you have activated carbon) I would recommend Seachem matrix (you can get this at Piper's...no, I'm not a Piper's employee). It's rocks (pumice I think) and it works the same way live rocks do. The rocks float though (very porous and can trap air) so you might need to put them in a bag in your sump (pantyhose works well.
). You can also try some purigen.
You will need some 5 gallon containers to hold your saltwater too. You can opt to make your own salt water using purified water or get natural saltwater.
-will 10k be sufficient for this setup?
more than enough in my opinion.
Now would be a good time to research on possible livestock. It would be best to start on the "easy" corals (mushrooms, zoas, etc..), but it's not easy to acquire these in Cebu.
I get mine from the beach. This is a good article from a fellow reefer:
http://www.chucksaddiction.com/reefcoll ... rtone.html if you want to collect on your own. Seth's advice is a good one too. Research on the kinds of fish you can keep in a nano tank and find how many you can keep in a 10 gallon.
Apologies for the wall of text, and happy reefing.
