Well former 2JZGTE owner here...call me a purist but that ain't no Supra..i would have opened the bonnet to a Pinto and still parked beside it.
When they collaborated with bmw i was fucking shocked.

But call it what you may, to me it looks like a Z4, i know they mod well but i would take a MK4 anyday.
right there with you man lol they sure made a hell of an atrocity with the new platform. they're not alone though. Subaru did the same thing with the BRZ. I think Toyota is struggling to be competitive in the sports car market so they're reaching out to companies that have maintained a long track record of producing reliable platform for that niche. Doesn't make a lot of sense to me given the new Camry's are not to be fucked with lol fast little grocery getters.

although the plants, vpd and the rez levels are all on point, i actually think Cinderella is on lockdown.
Last night syrange test came to 4.5ec. I did take the sample from upper area of the rockwool but nevertheless 4.5ec is just insane.
I'm not sure how correct this can be but i have a feeling that she is not happy. I think another flush is coming up to get these levels in the rockwool correct.

I've also noticed that my EcoPlus pump which i believe is 158gph, is really not that strong. Although the bed has a 3/4inch waterline with valve to control the amount of water that comes through, i am still not getting much water flow in the inlines for top of the rockwool. After confirming with @Dirtbag I did order another pump that is 400gph and should be arriving soon. If the pump is not the problem than i will go back to the drawing board and inspect the design flaw. Currently, the pump has a 3/4 inch water outlet that also has a small hole for the small inline pipes to the top of the rockwool. Im just thinking there is not enough pressure build up in the small hole of the adapter of the pump since the main line is a 3/4 inch.

One thing for sure tho, some of the plants are eating. My rez nutrient levels was at 1ec and yesterday i filled the rez up with four gallons of tap phed water and the ec was at 0.7. That did cheer me up and soon will be doing a water change. I'm sure once the water system is fixed these girls are going to rock out.

yeah, that pump is a baby man. i use the same one for mixing the res when making up new batches. it's simply not powerful enough for the volume of flow you need.

I'm using a Seaflo 33 series pump for my setup. Has plenty of pressure to run an 8 port manifold w/ 8 drippers. It's also self priming. Haven't had an issue with it and it has been rock solid. Stay away from the Flojet stuff. I had to return 2 that just didn't have the pressure they claim. Just throwing that out there.

Ecoplus submersibles are pond pumps, they can have decent GPM but they all have abysmal head pressure. I could stop the flow from a hose with a kleenex.
For my 16 plant manifold I use the eco1000 and it's just got enough jam to do the job. Nothing like a utility pump which I use to transfer solution through my filters going into the res. Those have excellent GPM as well as pressure.

ya, i think im going to keep it to make the process of emptying the rez easier. In the rez i have a submersible fan that mixes the nutrients but that is a good idea too. Thanks!!

Awesome thanks for the heads-up. I ordered a EcoPlus 400 so will see how this plays out. I think @tobh has one too and he was happy with it.

I would definitely take this road when these pumps fail. although i think i can only have 4 plants in the water bed

i have a 300gph, forget the brand, but it has decent enough head pressure to feed a six port manifold. Also ran 3/4" pvc with about 2ft of 1/2" polytubing in the middle under the platform so that there's a flex section in the piping. will likely modify that after this run as I don't really like the flexing and I have some ideas to make the system more stable overall. I imagine with that 1/2" polytubing taken out the volume at the terminations will increase as well since there won't be that constriction right in the middle of the supply line.

Im wondering how good/bad it is for the drain to go back into the rez? Is this okay or do i need to put the drain line into a different buck?

are you able to sterilize the return solution? are you running sterile? i mean, it's kind of a crapshoot with rockwool imo. this isn't like dwc or rdwc, there's a lot of area and opportunity for pathogens to take hold. that's why @Dirtbag runs the UV sterilizer and h2o2. that's the only way i'd do recirculating myself, if I had the space for all that plumbing.

I use Z7 enzymes. Here is the link with the information https://www.flyingskull.net/Flying-Skull-Z7-Enzyme-Cleanser-8-oz.html

Z7 is a super concentrated, two-part, commercial enzymatic cleanser. For best results, use Z7 at every watering/feeding. If using a reservoir, be sure to reapply Z7 every 3 days to maximize the enzymes' effectiveness.

• Compatible with any plant nutrient line, organic or synthetic!

• Probiotic formula won’t harm beneficial microbes in your growing medium.

• Keeps roots healthy by eliminating unhealthy salt build up on the roots and in the growing medium.

• Eliminates the need for harmful chemicals like chlorine and hydrogen peroxide.

• Keeps irrigation equipment like sprayers, irrigation pipes/tubing, pumps, and reservoirs clean and working efficiently.

• Reduces maintenance costs by keeping equipment clean.

• Eliminates plant death from plugged sprayers/drip irrigation.

• Super concentrated and economical; It only costs 2.5 cents per gallon of treated water (calculated using the MSRP).

• Safe to use – skin safe!

Hydroponic Application:
Shake bottles thoroughly. Add ½ mL/gal of each part to the reservoir after the nutrient solution has been pH adjusted. Reapply every three days or whenever adding more water to the reservoir, especially for recirculating systems, to keep the irrigation system clean and plants healthy. Water temperatures over 82 degrees may require increasing the frequency of adding Z7 to your system, up to every day, until all signs of root rot disappear.

i guess i shouldn't let the drain mix with the rez since i got no uv light or running sterile

you could though since you're running enzymes. 3ml/gal 29%+ h2o2. won't fuck with the enzymes and will keep shit sterile. still wouldn't put runoff back into main res though.

i can add h2o2 with enzymes? I thought h2o2 would kill the enzymes

enyzmes aren't living, they're proteins. h2o2 doesn't interact with them in a way that causes a molecular change whereas pool shock will. i ran enzymes + h2o2 my last run without problems, i just don't think they warrant the cost when 5ml/gallon 34% h2o2 is pretty concentrated shit and performs a similar action in terms of decomposing dead organic matter. plus, when buying a gallon of h2o2 that tends to be active for six months max, you wanna go through that shit as fast as you can.

tobh is 50% isopropyl same as h2o2?

Yea, the thing you want to watch though is too much; too much pressure can be a trap in and of itself. Depending on the setup. I think good quality pumps should have a nice range to work within.

That's what I was missing on this setup; I realize I've come in late. Is the return line under some plastic in there? Is some of the hardware in there covered up with plastic?
