have you considered trying out a t5ho retrofit for the 660?Apparently these Powerveg bulbs loose a lot of par over time. Ive had these what, a year and a half, close to 2 maybe? (not that that's a short time in T5 world) But check this out
Last week I'd checked Par in the dutch and it was about 80. wtf? Its supposed to be around 100. I assumed it was the old 3000K, probably 3 years old and normally a beast. Found the Plantmax brand that I wanted on at bulbs.com and they just happened to have the PVs.
So I decided to grab another 633 to replace a 660 in the farm tank, which I dont like with only 4 bulbs, too neony.
Well the new 3000K raised PAR about 5 points. Those things hold up VERY well.
Swapping out the PV 633 raised it....20!! And that was after a 1 hour warm up with a brand new bulb, hasnt even 'burned in' yet.
It must've gone down in a hurry over the last 6 months or so, because it was still around 100 then.
So Gregg you might wanna keep an eye on that 660...
Yeah those are intriguing, probably where we're all headed sooner or later. For me it'd all come down to color rendition, how the plants looked.have you considered trying out a t5ho retrofit for the 660?
there's probably a cheaper one on amazon
probably blasphemous in here lol
Yeah a digital ph pen, 20$-25$ off amazon is what I use. Just follow the instructions on storage and cleaning, and be sure to calibrate it often. You'll need to buy some calibration fluid/mixture as well. I use the little packets of powder and mix with distilled water.How are you guys measuring pH? Ph meter/pen? I'm realizing drop checker is not the most reliable way to measure c02. Thanks.
Seems my corner filter is a blessed thing, I dump everything in there! :grin2:So far Ive been adding it straight into the tanks, undiluted. As long as I pour it directly into the current from the filter outflows everything is fine.
No that was absolutely the BN pleco. Dont think I was even using HCL when that happened. Either way HCL melts plants. The tissue left on those was still strong and healthy. They were just chewed down to the nubs.A couple months back you made a post on Facebook I think or maybe I saw it in this thread, it was a bunch of staurogyne purple that got eaten up. You blamed it on bristlenose plecos. Do you think it was the HCL or is it still attributed to the plecos?

Well it turns out HCL can kill more than KH. It can also kill Dutch dreams. :nerd:

However, if I ever miss the center of the current stream the HCL just settles to the bottom, or wherever the side currents take it. You can see it travel due to the difference in opacity from water.
Ive burned up several plant groups being careless over the past couple of months. Melted an entire 12x6" wall of Buce mini coin in one tank, wiped out purple stauro in another, and several odd plants here and there along the way. Usually I dont notice until 3-4 days later when the plants start to melt. And melt they do! Completely.
Anywhoo, the latest casualty was about 3 weeks ago when I burned up 2/3 of the Blyxa novo in the Dutch tank. It's the lone specimen plant in a main focal point. Probably lost 75-100 leaves and what's left is pale and covered in fuzz algae. The contest deadline is next Sun the 15th.
Fortunately I have a couple of back up plans although Im not too crazy about any of them. So wish me luck...
Anything less than 'Best in Show' will be a disappointment! :bounce:
Edit: Oh and btw Im now adding the HCL to a 1 gal bucket of water first to dilute it before adding it to the tanks.
Damn, man. Sorry to see this. At least you have back up plans.Well it turns out HCL can kill more than KH. It can also kill Dutch dreams.
Thanks guys. Here's some light damage on Erio vietnam and Isoetes from a while back
Still have to be careful and not let it sit in one place. Especially the small tanks where it's more prone to happen for some reason. Im about to stop doing it, I believe. The vast majority of my plants dont need it. KH out of the tap is 6 which isnt very high in the first place. Just have to keep the true soft water species in the soil tanks.Wow that’s unfortunate, but at least it’s small enough for the plants to recover from. Have you found that the burning effect is eliminated when you pre-dilute the acid?
