First 75 Gal Saltwater tank almost complete. Any Suggestions for improvements?

75 Gal Tank home made stand housing a 3 chambered 20 Gal sump (1- Protein skimmer, 2-heater, Baffle w/ foam mesh stuff & round rocks, 3-return pump) Guy who had the sump before me plugged the holes so it looks a little janky, but at least it doesn't leak!

So Far:
Marineland Biowheel 330
700 GPH Overflow
Quiet One 2200 Return Pump
Odyssea PS 75 Protein Skimmer (Being Shipped)
Aqueon 300Watt Heater

To Come;
50Lbs Live Rock
2 1/2" Sand Bed
Odyssea 48" 216W (4x 54W) T5 HO Light 4 LED
(1 or 2) Koralia 400gph
Air Pump For Skimmer

Any suggestions on what I could improve on?? This is my first saltwater tank and want to try and do it right with a reliable clean tank. Planning on doing a FOWLR but maybe switch to reef when i get the hang of it and a little more money to sink in my baby.
Let me know what you guys think!
Also what would be the best way for adding water? ive heard using tap water and letting it sit overnight with conditioner works ok but will the other elements in the tap be a problem later with algae or something??

 

Looks good so far.

The best way to add water is to use R/O water. I have been using it for about 6 months, but I didn't start out with it. You could get buy with tap , but R/O makes all the difference in the world IMO.

The 1 or 2 Korlia's would get you buy for now, but if you plan on switching to a reef you will need way more flow. I have 2 Korlia #2's and 1 Korlia #1 on my 55g now. I will be switching out the Korlia #1 for a #2 very soon.

The 50lbs of LR will be fine for now. But again, if going with a reef you may need a little more rock.

Everything else looks good. Keep the pics comming!

 

+1 on the RO water. You'll head off much of the headache before it starts.

You can get some dry rock to add with your live rock. Over time, the dry rock will become live.

 

At first glance the biowheel is unnecessary, your biological filtration will happen in your sand and rocks.

+100 on RO/DI water, look into getting at least a 4-stage RO/DI unit from bulkreefsupply or spectrapure or something.

Do you have a refractometer? They are one of the basic essentials IMO and are relatively cheap. Much better than swing arm hydrometers. Make sure you get some calibration fluid as well. www.bulkreefsupply.com has them.

Do you have test kits for ammonia, nitrite and nitrate at least so you can monitor your cycle?

I would look into an auto-topoff system as well, they really make life a lot easier because you don't have to topoff water every day, just make sure it has redundant failsafes and isn't hooked up directly to your RO/DI unit because it's one of the easiest ways to get a flood.

Things to look for upgrading, I would look at upgrading your skimmer and lights but just based on the fact that they are on the lower end of quality they will probably be fine for a while.

 

yeah i am working on kinda a budget right now i just wanted to get a cheap skimmer for now to get it up and running and stuff. Im hoping to get an ASM Mini-G or G-1 maybe and some beter quality lights a little later on.

Also if i was to get on R/O how would I go about using it or hooking it up? I havent looked at them a lot yet so i dont know too much about them

 

That depends entirely on your house/apartment setup. You can use a variety of adapters to splice it into a water line. You can throw it on a faucet several different ways, you can put it under a sink and throw in an adapter between the shutoff valve and the supply line to the cold water faucet, you can use a saddle valve to pierce a cold water copper pipe.

Here are some options, some of them are extremely simple.
Reverse Osmosis Valves and Adaptors - English

This is what I use under my bathroom sink.
John Guest Angle Stop Valve 3/8" x 3/8" 1/4 push connect - English

 

That way you use looks like what i probably would use. Looks simple enough. hopefully ill be able to have this thing up and running by febuary lol

 

Yeah it's really simple, requires no permanent modifications, can be easily switched on and off (get an auto shutoff kit as well so even if you forget the unit will shut off!) and is easy to install. I would recommend it if you have room under your sink or if you don't mind having RO tubing running out from under the sink.

Good luck!
