How to measure cal reactor effluent with dhk ~25 with Hanna whose range is up to 20dhk max?

I did remove the head and just let the main unit run. Noise was still present.

My Cole Palmer Masterflex L/S digital pump has a slight metalic grinding noise coming from inside of the main unit. The noise occurs only when speed goes above 35 ml/min. It is present even when it runs whitout the external pump mounted. Does anybody notice this noise too, or I need to...

I have a kessil 360. I live in fremont near frys.

I can help if it is at or after 7:30pm.

I am thinking to buy a fish later today from Matt at Violet Sea Fish and Coral. Given my quarantine tank (IM 20G) has bubble algae, could the fish living there for a 2~3 weeks carry bubble algae into my display tank later on? I am willing to take the chance and put this new fish into the DT...

Boun11 - great to see you back in action!

I use a sharp knife to cut from their bottom. I do not know they have roots? The infested areas are in multiple new locations. What fish eat them? Thanks!

I picked off bubble algae from 2 disks a month ago. Unfortunately just noticed today that there are multiple places inside my IM 20g infested. Some are even on the surface of the sand. What should I do now? Is it time to remove all content, replace with new stand and new rocks, only transfer...

Do bubble algae know how to aim for the eye too? I plan to remove a few of them later tonite.

Are these the dreaded bubble algae? Luckily seen in my QT. To rid of them AND save the clovers, can I just pry them off the disk and rinse with salt water before putting back the clover/disk back to QT?

Just setup my calcium reactor. Wonder what is considered a good time for the solenoid to cycle on and off? Currently it is about 1.5 hours between two shut offs. To increase the duration of the solenoid cycle time (less frequent switch on and off), I am thinking the following: 1. Increase...

My heaters cluster draws just shy of 5 amp. It is currently plugged inoutlet #7 on EB8. No issue so far but thinking to relocate to outlet #4 or #8 which can sustain up to 10amp. Then I read some low power devices may not start correct in outlet 1-3 and 5-7. So shouldnt’t I keep heaters at its...

@lbn why not use rocks in place of marinepure blocks? I ended up putting in just a few weeks ago one 4x4x8 block and 0.5 cubic feet 2”x2”x2” cubes in my sump. I considered siporax then read about it may lead to elevated silica level. That was when I had a mental breakdown :-)
