[AquaClear 70 Power Filter]

@Lennie I absolutely do not mind at all. I could possibly make a video and send it to you or we can zoom/facetime so you can ask real time questions. Whatever works for you 

[AquaClear 70 Power Filter]

I clean hob’s with impeller once per month on all units, I’ve literally never had an issue. Not to say it’s the perfect filter because it doesn’t exist, but this is as close as I’ve found.

I have 6 110’s and 1 70 and I love them. I don’t even research anything else. Unless something is introduced that is a literal game changer, then I love/trust the tried and true. 

[KH/GH/pH Issues please help, fish shipment arrived today - thanks!]

I could be crazy, but I’m pretty sure you would be fine just using dechlorinator. I would buy locally and you’re most likely fine. Just my opinion. I’ve lived in a soft water state and now hard, I’ve never had an issue that a fish couldn’t acclimate to my water. I don’t keep sensitive fish like discus, do my regular maintenance and I’ve never had an issue. Over time, you’ll be able to notice things with a quick glance of your aquarium. I think you might be overthinking this a bit. If you want to tinker by all means, but as my doctor told me, sometimes it’s best to stay off webmd. 
ps that’s not discredit the fine advice you got above. If you decide to continue then you got some good stuff up above. 

[Moving aquariums twice in 2 weeks? Dumb or okay?]

I’ve moved with a 125 before and in my experience, as long as you take your time, go over everything as you’re doing it, then you should be good. The suggestions above are excellent and you should be successful.

Have you tried keeping Pygmy  Cory’s before and had bad luck? Or are you chasing numbers? Just curious. 

[KH/GH/pH Issues please help, fish shipment arrived today - thanks!]

What @Colu and @Tony s stated is what I do to the syllable. Personally, I’d get those fish out of those bags as soon as yesterday. Toss them in a tote with a sponge filter. 

[Old filters from 70’s]

This is fascinating, please keep us updated. 

[Paradise fish?]

Hey everybody, anybody keep paradise fish? I’m thinking of keeping either 1 or 6 in a 29. I prefer keeping 6 but have read males can be a bit aggresive at breeding times. Anyone have any personal experience with these guys? 

[In Search of a Good Algae Eater.]

Panda Garra is an excellent idea. Personally, I’d swap those mollies for some platies and amano shrimp. JMO

What size aquarium is it? 

[Broken impeller shaft on Fluval 407]

I’ve done this before and it works, you’ll be fine. I cannot tell you why or how, but I can tell you that afterwards, I had a mini bacterial bloom for 1-2 days and then all was well. I fed lightly until the canister was up and running again. I also seed my sponge filters by placing them in a stock pond with no air running through the ones to be seeded. I’ve pulled them out and have stocked an aquarium with them and never had an issue. Good luck, but I don’t think you’ll need it. PS awesome bala’s

[Steatocranus care?]

@T. Payne Since they move a bit clumsier than speedier fish, would you say they prefer a more sedate tank mate or either way works? You’ve got me curious. 

[Considering buying Co-Op live plants]

@Tony s my thumbs are as black as my x wife’s soul. All the plants in my aquarium go straight in. If they survive, cool. If not, I might try again. I’m definitely a fish first kinda dude. 

[Any other fish for this tank?]

Here’s the thing, you’ve posted about this before which tells a more experienced keeper that you’re a bit bored with your setup and would like to tinker with it a bit. More fish doesn’t necessarily mean more satisfaction. I suggest breeding because with these guys, you can use small totes/shoebox for fry. Once you implement an actual project, you’ll challenge your mind and get a bit more satisfaction out of it. Another reason I suggest this is I’m pretty sure your cycle is out of wack according to your previous posts as well. Become an expert with what you got and then stretch your tentacles once you master the tank/task at hand. 
This isn’t meant to be mean or anything, I just remember the same behaviors in myself and other newbie’s around me at the time. This is a big reason why people have many tanks. You could theoretically have a different tank to work on daily. However, when finances, space, or time is limited, I always look to get a project going in said aquarium. 

[Confused about minimum tank size]

6 is a number used for the high probability of getting a pair. It’s been stretched a bit to include schooling fish when in reality it is more like schools of hundreds. However that’s why 6 is used. 

[Confused about minimum tank size]

@gardenman I agree, however experience plays a huge factor in this equation. 

[Steatocranus care?]

Cory keeps these in a 40 breeder. Go to one of his last 6-7 videos and you’ll see how he has it setup and the tank mates that are housed with them. I wish I could recall and don’t quote me, but I’m pretty sure he’s got platys in there. 

[Any other fish for this tank?]

Breed the wcmm, then you’ll have more. 

[Confused about minimum tank size]

75 regular

40 short bodied but monitor and potentially move it up to a 55 if maintenance is too much or it looks cramped. 
29 gallon only for fry. I would never put anything that gets over 4” in a 29. 8” is just too big. 

[Confused about minimum tank size]

I had a flower horn in a 75 gallon. He wasn’t short bodied and he was quite large. Personally I’d never go with anything less than 75 for a full grown adult. With that said, a 40 gallon would be adequate for quite a while. 
When I would be looking to go bigger than 40:

1- it looks cramped and is bumping into stuff.

2- water parameters dependent on your indefinite water changes. If you can’t skip a water change because your parameters will go out of wack then I’d go larger.

I would approach this more of a see as I go, but I would not rule out needing something bigger. 

[Please help identify]

I could be totally wrong but the little guy tucked to the right make me say convict.

[Please help identify]

Looks like convicts to me. 

[Small pond newbie asking for stocking advice]

Tropical species won’t cut it with those temps. 

[Would this sand mix be potentially dangerous for future goldfish?]

Be vigilant with diet, all fancy type goldfish are susceptible to swim bladder issues that are almost always irreversible in the long run. Buy good quality to ensure better genetics, but honestly much like @Cory, fancy goldfish have me frustrated and stumped. They’re excellent and then they absolutely are not. For this reason, I keep Wakins. For the record, I adore fancy’s and hate that they have such health issues.
