With your HOB filter here is what I would do... You need the flow as you have no powerheads, in a reef aquarium you want to shoot for 5 to 10 up to 20 times turnover so in a 150 up to 3000 gallons per hour. In my 65 gallon I have 1015, but I keep a few sps corals. (they require massive intermittent flow) You really need flow to ensure that everything moves good and you keep debris from sinking to the bottom of the tank, It needs to stay in the water column to be filtered out by the skimmer or filter. In my HOB filter I keep Cheatomorph a macro algae to suck up excess nutrients. But as large as your tank is and with so little livestock you should have no issue so far, however, a good floor lamp placed over the filter and a little bit of plastic egg-crate in the overflow to keep the algae in and you will have a HOB DIY refuge.
As for you DIY rock, you have to use portland cement so that it is nothing but cement and no rock/sand... The sand in the rock you have already made will have silicates in it which will promote algae growth. But by looking at your pictures you already have tons of diatoms or slime algae and maybe some dinoflagellates.
You are off to a great start in the DIY section of the hobby, and the bargain hunting side. Even if the pump craps out on that cheap skimmer it is much easier to replace and the expensive part is the acrylic caste that makes up the actual removal and collection of skimmate. The next real step in equipment is either more water flow or lighting, but remember the e-bay is the place to go, that's where I've bought 90% of my equipment, such a wonderful place. Hit me up either here or in PM with the dimensions of your tank and I'll try to help you find more good cheap equipment
