Yea, 400g/hr is enough you could have spray blowing down back wall and nozzle at each top corner of tank blowing towards front wall.
Thanks, Dave. Yes, I've been investigating spray bars. Guessing I'll need to jury-rig something since I can't find anything ready built that'd fit the outlet of my Jebo internal sponge filter. So does one need to add a t-junction to have nozzles at each corner, and would that mean placing it in the center? Need to measure the filter outlet, but am wondering if I could use some flex tubing held in place with suction cup brackets and experiment with hole size & spacing to get the desired flow. Then after some McGyvering I could replace it with something more permanent like PVC piping. Probably won't look that good, but the plan is to have the back of the tank fill in with the Crypt balansase, jungle val, etc anyway.
Been busy so haven't been posting, but here's a one week update:
Tank is still kinda yellow from the tannins from the peat soil, and starting to get a lot of algae. Got a shipment of plants Fri that I've planted:
- jungle val
- Bacopa monnieri
- Proserpinaca palustrus
- Ludwigia Mini 'Super Red'
- Crypt balansae
The H. polysperma 'Tropic Sunset' planted earlier is doing well, the Java fern ragged but hanging on, the H. difformis melted but the crowns are showing some new growth, as is what's left of the ambulia. The Java moss & red root floater didn't survive the week in a bucket while I was setting up. Trying to locally source some other floaters like water sprite or hornwort, but oddly the big box stores don't seem to carry it, and I'm leaving town soon so won't have time to order any.
Water parameters: seem to be holding pretty steady. Have been dosing ammonia & Seachem Stability daily the first week, and did a 30% water change yesterday.
Here are the pre-WC readings:
- pH: 6.0
- ammonia: 1.0
- Total Hardness 50 mg/l
- nitrate 10 mg/l
- nitrite 0 mg/l
I'm away a couple of days this weekend, so it'll be interesting to see what they are when I return tomorrow. Leave for another 2 days, home a day, then away for another 2 days. So will do a 20% WC and dose more Stability (and ammonia if needed) in between trips--so 3x WC in one week. Hoping the new plants--esp the stem plants--will kick in and start soaking up those nitrates & ammonia.
Surprised to see the pH & hardness so low when it's 8.0 out of the tap, but I used the peat soil & SafeTsorb with its high CEC for precisely that reason. Wondering if the low pH is why the ammonia is still measurable? We'll see if the more frequent WC raises the pH some that will allow the bacteria to grow better and bring the ammonia down to zero.
Lighting: shooting for 8hr/day at 80% power using the timer module I ordered with my Beamswork DA FSPEC LED. Hoping I got it programmed right before leaving for the weekend--the instructions are a bad Chinese translation and virtually unintelligible, so it may take some trial & error to get it right. Just hope they're not staying on 24/7 and making the algae grow out of control. The MTS & 1 or 2 ramshorn are loving it. Surprisingly, the local PetSmart has some decent looking oto cats for $2.99 each. I keep reading that most otos are imported and often starving when they hit the stores, but these seem healthy so maybe they're tank raised and acclimated to eating flakes or wafers? If the ammonia gets to zero & stays there, am wondering if it'd be worth it to throw 2-3 of them in to keep the algae under control while I'm away. Could they survive on that alone for 13 days? I know it's a bit of a risk, but want to keep on top of the algae so I don't come back to an overgrown mess that could take months to get back under control. Or maybe some ghost shrimp? Don't think I can find any amanos locally.
