When the tank was running before I was doing 50% wc every week... 30 gallon a day works out to about 210 a week.... I did fix that leak in the bath tub tho so might not be a problem

Not really though because you're diluting not replacing. Dilution sees a portion of new water drain with the old. Most cold water drips work well if you place the drip emitter away from a drain. Cold water generally goes to the bottom of the tank so most of the new water is utilized.

I drip 50% volume daily on 3 tanks and see zero nitrates.

My drip has 1/4 line running around the room and either drilled drains or hobs to drain the tanks. You can use floats and pumps but I prefer gravity. Gravity hasn't failed me yet.

Gravity wouldn't really work for me it's got to go up before down, but I could just have the float ball thing in the sump and the return line in the main tank... Add that to a good refugium or algae scrubber I bet I could keep nitrates under control but it's something only doing would show

Absolutely. Scrubbers, pothos, plants are all good options. Drips work just fine if setup with floats and pumps but it's something you'll want to check and service often to make sure things are functioning properly.

Cold water does not go to the bottom of the tank in a drip system, if it’s a drip system, because there is no relative cold water. I currently drip 1 GPH on my 125G, but have done as little as 5-10 GPD.

I used a refrigerator ice maker tap to draw from the coldwater line, and an irrigation dripper to regulate flow:

Continuous water replacement is the best way to dilute/remove nitrates and keep a consistent balance of KH and GH in the aquarium (nitrAtes shouldn't be the only concern). However, specifically speaking to the nitrAte problem, if you have that problem, all that is necessary is a high porous bio media with a slow flow rate (see: #2 of the above-mentioned image).
