This is what I used I my 75 gal. Need a small pump and hang it off the back of the tank. I only ran it at night. I dosed hydrogen peroxide at 1ml per 10 gallons at night and microbactor7 in the morning. Took me about 4 months to beat dinos.
If they are only on OPs sandbed, is it likely those are the small cell amphidinium and UV doesn't work on those.
They are cool to have even if it ends up just being diatoms. Looking at all the different bacteria, copepods, etc is kinda cool under a microscope.I just ordered a microscope. It should be here by Friday
Should I still do my water change today or wait?
As long as the possible dinos are not smothering any corals, you could. It is advised no not do them when fighting dinos so you can starve the dino of a trace element they need to reproduce. Since you don't know yet though, one water change today should not hurt.
I have a 43 gallon red sea xl200. I believe the sump holds 8 or 9 gallons as well. Would the one you posted work for my tank? Also I assume you have to have a separate pump. What would work for that? I'm not really familiar with how they work. I know you adjust flow rates for whatever problem you're trying to solve. My husband said to just go ahead and order a uv because he's sure this will not be the last time we will need one.
You can always go bigger. It's too small you need to worry about. A 15W is the recommended size for your size tank.
I had a small pump laying around I used. Like the old mj1200. You don't need a lot of flow, 200 gph is all. Pull from the tank and back to the tank. I put a small cheap ball valve on the output side just to get some adjustment out of it.
What a differance from morning until after lights are on. I say it's Dinos. You also have diatoms but no worries about them. Need to get the dinos out first.
Alright these are with whites. The 2nd, 3rd, and 4th have the very tiny bubbles buts its only like 3 or 4 bubbles and very hard to see. You can also only see them with the whites on this morning. The other pictures are just other random spots of strands around the tank. I am about to start my water change and maybe see what I can get out with the siphon thingy. I thought maybe there were more short strands were bubbles yesterday but I'm not seeing them in the same places today. You'll also have to forgive the fact that I'm calling afternoon morning. My husband is a truck driver and our schedules aren't normal haha!
I bummed. I was really hoping not! How do I get then out? Should I wait until microscope comes Friday?
That will also kill your pods near that location and can cause macular degeneration if you look into it often enough. Contained units are much better.
